Everything About Blower: Functions, Types, Benefits

People new to industries take time to comprehend the differences between a Blower and a Fan. While everyone is busy launching or marketing innovating Blower Fans, we will provide you with factual data on Blower and its versatile uses, types, features, and benefits. 

Brief introduction on Blower’s Working Principle and Applications

A blower is a fan-type apparatus designed to provide high-pressure “blow-off” (airflow) that is focused. It cycles airflow for cooling, heating, exhausting, sucking, and drying. While some of its types are used as industrial blowers others are used as commercial and residential blowers. 

A blower is a mechanical device which consists of an impeller, rotating blades, and an electric motor. Like a fan, the blower uses its rotating blades to take air/gas inside the spinning impeller. The impeller’s motion and blade’s kinetic energy help to increase the pressure and velocity of the air at the outlet. The inlet pressure is low and outlet pressure is high. 

The types of blowers, industrial or domestic, vary on the basis of size, body design, blade design, power capacity and application. Types of the basis of airflow direction are: Centrifugal blower and positive-displacement blower.

Types on the basis of blade’s designs are:

• Forward-curved blades

• Backward-curved blades

• Radial 

Applications: Industrial Blowers, Equipment Blowers

To understand in the simplest way, let’s take an example of your hair dryer. It is a type of blower that is used for drying purpose. A leaf blower, for instance, is used to provide powerful airflow to clear the garden off leaves. Here, we found out two types, one for drying and another for leaf blowing. 

In factories like manufacturing industries, their processes generate lots of dangerous fumes and hazardous chemicals that are needed to be expelled outdoors to maintain indoor air quality. A suction blower is used to take in all air impurities and convey it to a storage bag. It is also used for effective cleaning and dusting in unreachable areas like windows edges and CPU cabinets. 

There are cooling blowers designed for cooling industrial equipment under operation. For ex, it is mounted to heatsink to dissipate heat from laptop or PC; it is used as HVAC component. 

Difference Between Blower v/s Fan 

Both are used for circulating air but their purpose differentiates them. A fan uses its blades to move a large volume of air to all corners of a space (for ex, a ceiling fan), while a blower consists of a fan housing using which it takes in air and directs it to a specific area or single-point location ( for ex, a heat sink in electronic device). 

A blower focuses outgoing air at a specific direction to provide powerful and focused airflow for the purpose of heating, drying, cooling, or exhausting. A fan uses less pressure to produce a large volume of airflow, while a blower uses high pressure to produce a focused amount of airflow. 

The fan’s pressure ratio is 1:1 whereas the blower’s pressure ration is from 1:1 to 1:2. The former can be categorized as axial flow fans, centrifugal fans, and cross-flow fans; and the latter can be categorized as centrifugal blowers and positive-displacement blowers.  

Purchasing Criteria Of Blower 

When it comes to buying Blower in bulk, you need to consider a few important factors such as: 

• For small tasks, choose a battery-operated blower which is small in size and light in weight.

• Choose electrical blowers for covering a large area. 

• Make sure the device does not produce any mechanical sound when operated.

• Determine blower’s energy efficiency 

• Considering operational cost and maintenance duration

Some industrial fans are centrifugal fans and others axial fans, which means different applications have different requirement for which manufacturers and designers work together to produce an ideal product. Get into depths of this product before beginning with smart dealing.

How do Axial Fans work?

Axial Fans suck air inside the fan housing in the axial direction and force the air to exit the housing in the same direction, which is parallel to the axis where shaft is situated. The fan usually has 2 to 20 blades connected to the shaft. In a nutshell, the air enters and exits the fan in one direction which is axial direction – parallel to the shaft. 

Components, Designs and Characteristics 

The fan’s blades can be forward curved, backward curved, or straight – these special designs aid in high airflow with low air resistance, which increases the axial fan’s performance. The blades are usually made of aluminum.

The fan housing is usually made of steel, aluminum or alloys, which protects all housed components from spillage, vibration, shocks, external damage, and so on. The impellers are made of black-coloured aluminum, steel, or thermoplastic, and built to resist high corrosion. However, the thermoplastic impellers are specifically used for residential-grade axial fans. The fan is designed to resist corrosive materials, extreme temperatures, flames, vibrations, shocks, etc.

What are the Applications of Axial Fans?

• Cooling of work areas, buildings and large spaces

• Spot cooling of industrial equipment, transformers, and generators   

• Process cooling in machinery or systems, such as computer’s CPU

• Ventilation in factories, automobile workplace, warehouse, equipment rooms, garages, etc.

• Removing toxic, hazardous or/and flammable fumes or gases from paint spray booths, welding booths, steel mills, paper mills, industrial washing, etc.

Benefits of Using Residential/Industrial Axial Fans

Axial Flow Fan: Working Principle, Designs and Benefits

There’s a reason why typical industrial fans are not being used for residential purposes. A fan can serve both the applications but can still differ on grounds of airflow rate, velocity, and volume. For ex, an Axial Flow Fan serves both the applications as it is designed for cooling machines, equipment's and a confined space. There are both AC and DC axial flow fans.

The basic components of an Axial Flow Fan include the motor, blades, ball bearings, impellers, and the fan housing. High-quality materials are used to design a strong, durable, and energy-efficient fan. To gather more information on product description, characteristics and benefits, contact India’s leading axial flow fan manufacturers, suppliers and dealers at Tradeindia.

The fan housing or enclosure is made of steel, aluminum or alloys, which protects the main components from external damage, spillage, vibration, shocks, and so on. The impellers are made of black-painted aluminum, thermoplastic, or steel, and built to resist high corrosion. The thermoplastic impellers are specifically used for residential-grade axial fans. 

There can be 2 to 20 blades that are connected to a shaft, containing a motor, which is placed parallel to the direction of airflow. The blades are usually made of aluminum. The overall structure of this fan is built to resist extreme temperatures, corrosive materials, flames, shocks, vibrations, etc.

What is the Working Principle of an Axial Flow Fan? 

An Axial Flow Fan causes air or gas to flow through it in linear direction or an axial direction, i.e. parallel to its axis where a shaft is present about which high-spinning blades rotate. In simple words, the air enters and exists the fan in same direction i.e., horizontally through the axis, which creates air flow with high flow rate and a large volume.  

The blades can be forward curved, backward curved, or straight. This special design aids in high airflow and low air resistance, increasing axial fan’s performance. The blades throw air against the resistance of all other components and provide high airflow for intended use.

What are the Applications of Axial Flow Fans?

Because of its rigid construction and long durability, it is used for:

• Process cooling in machinery or systems (like CPU)

• Cooling of work areas, buildings and large spaces

• Spot cooling of industrial equipment, generators, and transformers  

• Ventilation in automobile house, warehouse, factories, garages, equipment rooms, etc.

• Removing toxic gases and hazardous fumes from paint spray booths, steel mills, welding booths, paper mills, industrial washing, etc.

What is the Difference Between Centrifugal Fan v/s Axial Flow Fan

In an Axial Flow Fan, the air enters the fan’s main housing in an axial direction i.e., parallel to the shaft about which curved blades rotate. Also, the air exits the fan in the same direction without any deflection. On the other hand, the air enters a Centrifugal Fan from sides but the direction of airflow turns complete 90 degree (right angle) when exits the fan. This is the main difference between an Axial Fan and a Centrifugal Fan.

Benefits of Using Residential/Industrial Axial Flow Fan

1. Efficient Airflow: The industrial axial flow fan offers efficient airflow with increased velocity and volume, and that is it is used as a cooling tower and an exhaust fan too. These fans produce a large volume of air and even air distribution due to specially-designed curved blades. 

2. Increased Durability: Most axial flow fans are made from high-quality steel or aluminum material, which make them reliable, durable, lightweight, and user-friendly simultaneously. Their durable construction is the reason why they are being used in aerospace, ships, and hydrofoils.

3. Quick Maintenance: As these fans are compact and lightweight designs, they are easier to inspect and maintain than other industry fan types. Their simple design helps user to detect defects easily. 

4. Less Noisy Operation: These fans produce low mechanical noises like rattling sound as compared to conventional fans. Therefore, they are an ideal choice for applications where noise tolerance is zero or quite necessary.

Which Ventilation Systems for Home and Industry? Know Types, Benefits

Even lying down to spend time with self is a job! Looking after home, working nine hours a day, and daily travelling is enough to take up all energy a person stores when he sleeps at night. In this busy schedule to keep up with the basic lifestyle, some of the health tips are being gradually underrated – one of which is fresh air ventilation in your personal rooms.

Proper air ventilation of home via Ventilation Systems or Natural Ventilation will not only move fresh air inside the whole house but also impart freshness to furniture, curtains, hanging and laying household items, helping in extending their lifespan. 

So, there’s a package of benefits that will cater both to human beings by providing fresh breathable air, as well as, to non-living items by diluting the pollutants originating indoor and impacting items’ properties. In case of technical information or purchase, contact Tradeindia’s Ventilation Systems manufacturers, suppliers and dealers.

Moreover, the structures were historically supposed to be ventilated through natural means, like opening a door or window to allow fresh air into the space. But, with such growing world and greater advancements in air-sealing methodologies for buildings, mechanical ventilation is the best way for removing stale indoor air out and bringing fresh air. 

Basically, Ventilation Systems apply a method of using ducts, exhaust systems, or sensors for moving fresh outdoor air into the space and distributing it in the area. This system is required for spaces like homes, residential buildings, offices, storage rooms, chemical labs, pharmaceuticals, manufacturing industries, and other applications where it is important to remove hazardous indoor air to protect life and property.

Types of Ventilation Systems

Typically, there are three types: Natural Ventilation, Mechanical Ventilation, and Mixed-Mode ventilation. Let’s have a quick glance to decide which Ventilation Systems is best for what application and why. 

1. Natural Ventilation

It follows the natural process of outdoor air flowing into a building through planned openings, such as doors, windows, and louvers. The effect is intensified with physical phenomena, such as high wind pressure. When the flow of air from outdoors to indoors is achieved through air leaks, cracks or other accidental openings, it is called as infiltration.

2. Mechanical Ventilation

It follows the process of using mechanical devices, such as ceiling fans and exhaust fans, to drive air from outdoors to indoors into a building. The system may employ filtration systems to remove harmful microorganisms. This type can be categorized into:

a. Exhaust ventilation systems: It works by depressurizing the room or a building, relatively lower than outdoor air pressure. It causes outdoor air to enter a building through leaks (infiltration process) and passive vents. 

They are inexpensive and easy to install as it consists of a single fan attached to a central exhaust point. Ducts in each room can enhance the overall performance. It is perfect for cooler climates.

b. Supply ventilation: The system consists of a fan and duct system that pulls fresh air into one or more rooms of a building through ducts. This is achieved by pressurizing the building and, therefore, may have the potential to cause moisture issues in winters. 

c. Balanced ventilation: Neither pressurizing nor depressurizing, it works by exhausting polluted inside air and simultaneously introducing equal quantities fresh outside air. This system has two fans and two duct systems to achieve distribute fresh air in each room through connected ducts. It is appropriate for all seasons.

d. Energy-recovery ventilation: It is controlled way of ventilation while reducing energy loss. Though it costs more to install than any other similar systems, it attempts to recover all the energy to reduce monthly electricity bill. It can nicely fit with the existing ductwork system with just the need of correct size of duct. 

There are two types of energy recovery systems: Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs). Both include one or more fans and a heat exchanger. The models include: small wall-mounted, window-mounted, and whole-house ventilation.

3. Mixed-Mode Ventilation 

It uses both natural and mechanical components at the same time, or at different timeframes, or in different seasons. For example, the use of fan (mechanical components) in summers to move a large volume of air because simply opening doors and windows was not sufficient to move air. 

The reason why ventilation of a house, chemical lab or industry is necessary is that air pressure builds up in a confined space, where hazardous or flammable components of air can potentially spark fire after a point. So, it is important to exchange indoor polluted air and fresh outdoor air.

The Ventilation Systems can be semi-automatic or fully-automatic design with warranty of a few years. The benefits are guaranteed as they are designed using cutting-edge technology and under guidance and supervision of technical experts, as well as, according to the national and international quality standards.

Disposable Medical Device: Sterile, Reusable or Not?

When it comes to reusing a medical product or disposing it, the healthcare professionals usually recommend single-use medical devices. However, the definition of Disposable Medical Device varies on two categories:

1. Single-use devices for one patient only, and 

2. Disposable medical products that are intended for temporary use by a single person for a limited period of time. 

The hospital products in the first category come sterile i.e., they are sterilized by the manufacturers and then packaged before they are delivered to concerned medical facility, healthcare institute, clinic or nursing homes. They are not intended for reuse or re-sterilization process as they are mostly used for diagnosing, assessing, monitoring, and treating patients. 

Oral and surgical products, for instance, are used for single time. As they come in direct contact with one patient’s blood, radioactivity, infection or tissues and therefore must be disposed to eliminate risk of cross-contamination and spread of diseases. 

Disposable Medical Devices have shorter lifespan and are limited to one patient. The main reason for manufacturing and using disposable products is infection control. Some most common examples include:

1. Internal devices: Syringes, hypodermic needles, suction catheters, tubes, etc.

2. External devices: Drug tests, surgical gloves, bandages and wraps, surgical face masks, and surgical sponges, etc.

They are cost-effective and defined by the FDA organization as single-use, single-patient to maintain contamination-free and hygienic healthcare facility environment. Also, they are meant to reduce time and energy wasted in re-sterilization procedure, as well as, the concerns regarding unsafe re-decontamination or re-disinfection not as effective as the first time that tend to spark hazardous reactions.

Are Disposable Medical Devices Sterile?

As they are meant for single-time use, they come sterile that means they are sterilized by the manufacturers using advance technology, like moist heat (steam) vaporized hydrogen peroxide, radiation or dry heat method. 

Are Disposable Medical Devices Reusable or Not?

They are manufactured with such material, like polycarbonate, that makes it impossible to properly disinfect, sterilize or decontaminate the product, which could possibly be unhygienic and life-threatening if reused and cause cross-contamination. 

Is Mineral Water Healthy & Safe For Drinking?

 With 71% of the earth’s surface covered with water, only 3% of it is fresh. The immense development in the industrial sector, as well as, the ever-increasing population across the world adds to the excessive water consumption. This implies the expansion, progress, and growth are directly proportional to the increasing need for water.

We, being a part of the rising culture, have sought ways for Sustainable Development to secure our next generation and others. Mineral Water is one of the determining missions to ensure our next generation wouldn’t have to compromise. Life is precious and so does water! However, people have raised questions due to their insecurity whether Mineral Water is safe for drinking or not. Find the best solutions to your queries in this 3-minute-read blog.

Is Mineral Water Safe?

It is approved by the European Union (EU) and the U.S. Food and Drug Administration (FDA) and considered as healthy drinking water because it naturally contains essential minerals that are required by a human body for healthy living, recovery from disease, and full-fledged growth. 

Brief Introduction 

Mineral Water is the freshwater that is obtained from different underground water sources, which are physically and geologically secured and protected to provide a stream of natural drinking water for drinking purposes, as well as, for therapeutic usages.

As it is obtained directly from the mineral spring, it is bottled at the source for consumption and distributed consumption. People can't travel to the mineral water site for direct access to this water, therefore, several brands commercially manage to bring it, package it, and further sell it at a good price.

Composition 

Mineral Water naturally contains several essential minerals, including salts, sulfur components, calcium, chloride, magnesium, sodium, and potassium, and therefore no minerals are added to it. No mineral is added into the water by any means, as well as, doesn’t have to go through the disinfection treatment procedure. 

According to data, this water contains at least 250 parts per million total dissolved solids (TDS). It goes through a few treatment processes, such as flocculation, sedimentation, and filtration processes that help to treat the water and removes all the impurities to make it available for drinking. 

How Mineral Water is Different from Tap Water?

Tap water is comparably less pure and hence, it undergoes a chemical disinfection process for the removal of non-healthy and toxic components. Furthermore, it goes through a process during which essential minerals are added to it to make the water suitable for public consumption and other necessary works.  

On the other hand, Mineral Water is already mineral-rich as it is obtained from underground water sources. Therefore, no minerals are added to mineral water. Also, it does not undergo disinfection treatment. This makes it more pure and safe than purified water too.

The lifespan of Mineral Water

Though natural water never expires, bottled or packaged mineral water can. The minimum lifespan of these is about two years from the date of manufacturing. 

Health Benefits of Mineral Water

Mineral Water contains several nutrients like magnesium, chloride, sulfate, calcium, iron, etc. All these nutrients are essential for the human body to function at its best pace. 

It helps to regulate oxygen in the body.

It regulates and maintains the acid in the stomach and intestines which help in good digestion and prevent stomach- and kidney-related diseases.

It helps to reduce stress and strengthen the immune system.

Also, it helps in strengthening bones, reducing bad cholesterol, maintaining healthy digestion, enhancing skin texture, and preventing muscle cramps.

Benefits of Hypodermic Needle in Medicine

According to research data, the use of a Hypodermic Needle to inject liquid medicines into the body or to extract body fluids enables various benefits as compared to a regular needle. Since hypodermic needles come with a smaller diameter, it causes no or less pain for the user. Also, the data suggest its utilization has less vein damage.

Structure and Material 

A Hypodermic Needle is the widely trusted medical needle used across the world by doctors and nurses at medical facilities, nursing homes, and clinics. It is a thin and hollow tube with a sharp tip; the whole body structure is constructed from high-quality stainless steel. The hollow tube is made by the tube drawing process which uses a special type of dies to form sharp needles.

Main Purpose of Hypodermic Needle

This needle got its name from Greek words, where Hypo means ‘under’ and derma means ‘skin’, which means this needle penetrates the skin for two main purposes:

1. To deliver a medicinal drug into a vein or in the muscle.

2. To extract fluids, like blood, from the body. 

Hypodermic Needle v/s syringe

These needles are detachable and thus, always used in combination with a syringe. A syringe is a hand-operated device with a sliding plunger inside its cylindrical tube. When this sharp needle is fixed onto the given port in the syringe, the plunger inside the syringe body is pulled back to draw in a liquid drug. Then the needle is inserted into the skin while the plunger is pushed in to deliver the medication into the body, under the skin.

In a nutshell, both are two separate devices where the needle is the detachable part. One can use a single syringe with many needles of different sizes. The Hypodermic Needle is fixed on to the tip of a syringe.

Size of Disposable Hypodermic Needle

This needle comes in different sizes that are measured in Birmingham gauge (G). The classification is done according to:

1. Common medical purpose: The smallest needle’s size is 33-G while the largest size is 7-G. 

2. Blood test purpose: A needle of 21-G in size is used to extract blood from the fingertip for blood test.

3. Blood donation purpose: 16-G and 17-G sized needles are used for blood donation. 

 The smallest size of the needle is 33-G with a diameter 0.159 mm and the largest size is 7-G with diameter 3.810 ± 0.076 mm. The size varies from 7-G to 33-G.

Reusable or Not?

As these needles come in direct contact with the person’s body fluid, the risk of cross contamination increases. Therefore, they are intended for single-time use to reduce risk of cross-contamination and promote infection control and hygiene.

Why Doctors Trust Disposable Hypodermic Needle?

As much hygiene is important in-home, it is widely practiced in medical facilities. Keeping in mind the need of maintaining a safe surrounding for people, doctors emphasize the use of a Disposable Hypodermic Needle. This sharp needle is detachable; it is fixed on to the top section of a syringe for two main purposes: 

1. To supply medicinal liquid or fluid into the vein or under the muscle of a patient for treatment purposes.  

2. To extract body fluid (blood, tissue or cell)

A Disposable Hypodermic Needle is a thin and hollow tube with a sharp tip that makes it easy to penetrate through the skin. It is the most common needle used in medical facilities, nursing homes and clinic across the world to either deliver a liquid medicine or to extract blood from the body. 

It is always used in combination with a syringe, which consists of a sliding plunger inside its cylindrical tube. When this sharp needle is fixed on to the given port in the syringe, the plunger inside the syringe body is pulled back to draw in a liquid drug. Then the needle is inserted into the skin while the plunger is pushed in to deliver the medication into the body, under the skin. 

Is Disposable Hypodermic Needle reusable?

The Disposable Hypodermic Needle is only intended for single-time use and for one patient only. As it gets in direct contact with the patient’s body fluid, like blood and tissue, it is necessary to dispose it after one-time use to prevent cross-contamination.

It is non-reusable for infection control, hospital hygiene maintenance, and safety of patient. It comes in direct contact with human blood, tissues and infection, and must therefore be discarded after one-time use. They must not be reused as it has potential to spark cross-contamination. 

Material of Construction 

A Disposable Hypodermic Needle is typically made from a stainless-steel. The tube is made through a process called as tube drawing – the process in which the tube is formed through dies to make the sharp needle. 

Size of Disposable Hypodermic Needle

It is available in different sizes that are measured in Birmingham gauge (G). The smallest size of the needle is 33-G with diameter 0.159 mm and the largest size is 7-G with diameter 3.810 ± 0.076 mm. The size varies from 7-G to 33-G.

Duplex Steel Plates: Everything You Need To Know

Duplex Steel Plates (short form of Duplex Stainless Steel) are the widely used products in most of the applications. It is a unique combination of high strength, hardness and excellent corrosion resistance. This is a result of its metallurgical structure which consists of two phases i.e., austenite and ferrite. This special structure provides better strength and enhanced corrosion resistance property than stainless steel and mild steel.

Chemical composition of Duplex Steel

20-28% Chromium (Cr), up to 5% higher Molybdenum (Mo), up to 9% Nickel (Ni), and 0.05-0.50% Nitrogen (N)

“At Tradeindia, check out latest online price details of Duplex Steel Plates & companies selling them at best prices.”

Stainless Steel v/s Duplex Steel Plates  

The main difference between duplex steel and stainless steel (SS) is in their chemical compositions. The duplex has higher chromium (up to 28%) and molybdenum contents than that of SS containing only 11% chromium and lower molybdenum.

The higher the chromium content, the higher the yield strength. Thus, this difference in the composition makes duplex-grade steel better corrosion-resistant material than stainless steel. Though both the materials have similar toughness and durability, the former has higher resistance levels to chloride stress corrosion and chloride pitting corrosion and twice the stronger than the latter.

Super Duplex v/s Duplex Steel Plates 

Super duplex, as the name implies, is superior than Duplex Steel Plates because of the higher contents of Cr, Ni, Mo, N and even W which endorse the formation of intermetallic phases, making it more resistant to impacts and stronger than duplex steel.

Features & Properties

1. Excellent resistance against corrosion, intergranular corrosion, chloride pitting, stress corrosion, cracking.

2. Due to high chromium content, Duplex Steel Plates can withstand high temperature of 300°C and above.

3. Machinability & weldability

4. High tensile strength and yield strength

Oxygen Generator: Economical Source of Oxygen

An Oxygen Generator is the soul of multiple industries which require oxygen (O2) as a main component to operate, aid other equipment, & produce beneficial results on daily basis. From small-sized like a soda can to large-sized like a bus, this device is manufactured utilizing cutting-edge technology to ensure demands are met as per national & international quality standards.

How Does An Oxygen Generator Work?

The working principle of an O2 generator is to supply oxygen-rich gas after compressing & filtering the ambient air, followed by adsorption of nitrogen onto zeolite mineral (an adsorbent) that acts as a “molecular sieve”.

A oxygen concentrator consists of an air compressor, a pressure equalizing reservoir, two cylinders filled with zeolite pellets, and some valves &tubes. It uses Pressure Swing Adsorption (PSA) technology – a highly efficient & reliable technology for small & medium capacities. 

It takes in ambient air, compresses & filters the air. Then the compressed air enters the first column filled with the adsorbent (zeolite) which traps nitrogen & some other gases, leaving oxygen as the primary gas remaining to flow through. When the column is active, the second column works to regenerate & switch place with the first one at the end of the cycle. This makes the device to produce a constant flow of purified oxygen.

The produces 90-95% pure oxygen gas. Repetition of the process can be done to generate over 99% pure oxygen. On the plus point, this same device can also be used to generate nitrogen by using PSA technology. 

Vast Area of Applications 

The Oxygen Generator is used in an extensive range of applications, including medical, pharmaceutical, gold mining fish farm, aquaculture, sewage & waste water treatment, oil refineries

It is an economical source of oxygen.

Portable oxygen generator is used as medical device in hospitals & homes. It is used in steel manufacturing industry, glass blowing, pulp & paper manufacturing, welding & several other industries.  

Features & Benefits

How Oxygen Cylinder Is Different From O2 Tank?

Have you ever wondered how your body functions like a 24x7 machine to breath in Oxygen (O) & breath out Carbon dioxide (CO2)! The nature is unexplainable. But when it comes down to machinery world, it requires a set of equipment & procedures to do so.

Atmospheric air is the natural source of oxygen, containing 20.8% oxygen. This concentration is enough for animal breathing process, fueling, & metal corrosion. But there are numerous applications that require concentrated amount of oxygen to operate & that’s when Oxygen Cylinder comes into the play.

Constructional Material

This lightweight, portable & circular-cylindrical high-pressure container is manufactured by hot forged seamless steel. The standard pressure is 200 (3000 psi) bars. It’s being used in the manufacturing of welding & cutting, steel & monel, medical breathing gas, scuba diving, & emergency backup in aircraft. 

Carbon steel is also a good corrosion resistant material that is being used. Brownmillerite-type materials are also used. Other materials include glass-reinforced plastic, polyethylene & thermoplastic.

Difference Between Oxygen Cylinder & Oxygen Concentrator

You will always find the use of terms oxygen cylinder & oxygen concentrator interchangeably. In contrary to that, they aren’t same. 

Oxygen Concentrator: Using rapid Pressure Swing Adsorption (PSA) mechanism, the concentrator separates oxygen from the gaseous mixture. It uses zeolite mineral as adsorbent to adsorb nitrogen from the atmospheric air, leaving other components to pass through, leaving oxygen as the only remaining gas component. It supplies oxygen on continuous flow.

Oxygen Cylinder: It is a medical oxygen tank that contains a specific amount of oxygen & can run out after a while. These cylinders can be refilled & reused for multiple times, however, may require periodic maintenance service. 

Types of Oxygen Cylinders

• Compressed gas system: It’s an O2 concentrator that is widely used as a stationary & portable medical oxygen provider at medical facilities & homes. It supplies O2 on continuous flow. 
• Unpressurized oxygen cylinder: It aids in breathing at high altitudes & in emergency situations too. 
• Cryogenic storage tank: It’s a vacuum-insulated flask that contains liquid oxygen. It is used in gas industries, submarine & aerospace. 
• This system delivers O2 to the users via oxygen mask, oxygen tent, nasal cannula, full face diving mask, diving helmet, built in breathing system (BIBS), oxygen rebreather, demand valve, & hyperbaric oxygen chamber.
• It contains about varying purity of compressed oxygen. Its durable in nature, however, require inspection & pressure test to ensure its structural & functional stability. It is supplied in various sizes & pressure capacity, depending on the application. 

Area of Application

An oxygen cylinder is commonly used in medical facilities, homes, aircraft emergency breathing, diving, welding & cutting, metallurgy, aquaculture industry, military or disaster situations, fuel gas cutting, lampworking torches, etc.
