More About Axial Fans: Function, Designs and Characteristics

Whenever the mankind is attacked, it overcomes with unique discoveries and inventions. Similarly, when industries and businesses come face-to-face with an issue, they come up with new ideas. To cater to your business and support new ideas, Tradeindia presents highly-demanded Axial Fans offered by India’s leading manufacturers, suppliers and dealers at best deals.

Why Axial Fans? Because as the world is developing, there is a need for innovations. 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.

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.
