How to Choose the Best Axial Flow Fan for Industrial Use

When it comes to industrial ventilation and cooling, axial flow fans are a go-to solution for efficient air movement. These fans are widely used in factories, warehouses, HVAC systems, agricultural buildings, and more. However, selecting the right axial flow fan isn’t always straightforward—it depends on various factors specific to your application.

At Perkins Blowers, one of India’s leading manufacturers of high-performance axial flow fans, we understand how crucial it is to choose the right fan for optimal efficiency, reliability, and cost-effectiveness. Here’s a comprehensive guide to help you make the right choice.

1. Understand Your Application

Begin by identifying the purpose of the fan:

Is it for general ventilation, spot cooling, exhaust, or air circulation?
Are you dealing with clean air, dusty environments, or corrosive gases?

This helps determine the fan design, material, and motor protection level required.

2. Calculate the Required Air Volume (CFM)

CFM (Cubic Feet per Minute) is the volume of air the fan needs to move. To calculate:

Assess the size of the area (length × width × height).
Determine the number of air changes needed per hour (ACH).

Then use this formula:

CFM = (Area Volume × ACH) / 60

At Perkins Blowers, we offer fans ranging from 1000 to 1,00,000+ CFM to suit diverse requirements.

3. Determine Static Pressure

Static pressure is the resistance the fan must overcome to move air through ducts, filters, or louvers. It is measured in inches of water gauge (in. wg). Higher pressure requires fans with stronger blades and motors.

Tip: For applications like dust extraction or filtered air systems, static pressure plays a bigger role.

4. Consider Fan Size and Blade Type

Axial fans come in various diameters, from 300mm to 1500mm or more. Blade type also matters:

Aluminum or FRP blades for corrosion resistance.
Aerofoil blades for high efficiency and low noise.
Cast aluminum blades for durability in heavy-duty environments.

At Perkins Blowers, we customize blade materials and shapes to meet the demands of your industry.

5. Choose the Right Drive Type

There are two main types:

Direct Drive Fans – Compact, lower maintenance, and suitable for limited space.
Belt Drive Fans – Allow flexibility in speed adjustment and are suitable for higher loads.

Let Perkins Blowers assist in selecting the best configuration based on your operating environment.

6. Evaluate Noise Levels

Axial fans can be noisy depending on speed and blade design. If noise is a concern—such as in commercial or residential ventilation—choose fans designed for low-noise operation. We offer acoustic enclosures and optimized blade profiles to meet such requirements.

7. Check Energy Efficiency

Choose motors with high efficiency (IE2, IE3 standards) to reduce power consumption. Variable frequency drives (VFDs) can also help regulate speed based on demand, cutting down operational costs.

8. Look at the Build Quality & After-Sales Support

Finally, ensure your fan is made from durable materials, complies with industrial standards, and is supported by a reliable after-sales service team.
