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

1. Efficient Airflow: Axial Fans provide efficient and high-volume airflow – that is why they are used as cooling towers and exhaust fans. Their cooling, ventilating and exhausting efficiency is higher than any conventional fans. They evenly distribute air with using its specially-designed curved blades. 

2. Quick Maintenance: As these fans are compact with no heavy components, they are easier to maintain and repair than other industry fan types. 

3. Improved Durability: Mostly, Axial Fans are made from high-quality steel or aluminum, which makes them sturdy, durable, reliable and user-friendly, simultaneously. Its durable construction is the prime reason why it is being used in aerospace, ships, and hydrofoils.

4. Quite Operation: These fans produce no or low mechanical noises, like rattling sound, as compared to other industrial or commercial fans. Therefore, they make up to an ideal choice for applications where noise tolerance quite necessary.

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.
