The Fan Material Guide | Industrial Fan Construction

10.08.2025

When it comes to industrial fans and blowers, performance is not only determined by design but also by the fan material used in construction. Selecting the correct material ensures durability, resistance to harsh environments, and safe operation across different applications. At Fans and Blowers, we engineer our centrifugal and axial fans using carefully chosen materials to meet the specific demands of each industry.

Why Fan Material Matters

The material used to build a fan’s impeller, housing, and other key components directly impacts:

Corrosion Resistance – Preventing damage in environments with moisture, chemicals, or abrasive particles.
Strength and Durability – Withstanding high rotational speeds, pressure, and mechanical stress.
Temperature Resistance – Maintaining integrity in high-heat processes.
Hygiene Standards – Ensuring compliance in industries like food and pharmaceuticals.

Choosing the wrong fan material can lead to premature failure, contamination, or costly downtime.

Common Fan Materials in Industrial Applications

1. Mild Steel

Widely used for general-purpose fans.
Strong, cost-effective, and suitable for standard air-handling tasks.
Often coated or painted for additional protection.

Best for: HVAC systems, general ventilation, and non-corrosive environments.

2. Stainless Steel

Excellent resistance to moisture, chemicals, and high temperatures.
Ideal for industries with hygiene requirements.
Available in grades such as 304 and 316 for enhanced corrosion protection.

Best for: Food processing, pharmaceuticals, chemical plants, and marine applications.

3. Aluminium

Lightweight yet strong, reducing strain on the motor.
Naturally corrosion-resistant and suitable for portable fan units.
Performs well in medium-duty environments.

Best for: Lightweight construction fans, blowers, and HVAC applications.

4. FRP (Fibre-Reinforced Plastic) & Composites

Highly resistant to aggressive chemicals and corrosive gases.
Lightweight but durable.
Non-conductive and often chosen for safety in hazardous environments.

Best for: Chemical plants, wastewater treatment, and corrosive fume extraction.

5. Specialised Coatings & Linings

Epoxy or polymer coatings can extend fan life.
Provides an extra layer of resistance against abrasion, moisture, or corrosives.

Best for: Dusty environments, spray booths, and industrial drying systems.

How Fans and Blowers Select Materials

At Fans and Blowers, we don’t believe in one-size-fits-all. Each of our centrifugal and axial fans is built to specification, with fan material chosen based on:

Operating temperature
Pressure requirements
Gas or air composition
Expected wear and tear
Industry-specific standards

For example, our BSNZ Centrifugal Fan may be constructed in mild steel for general duty, while our GXZ Gas Exhaust Fan can be manufactured in stainless steel for handling hot, corrosive gases.
