Fan Materials are a major component of engineering and manufacturing a centrifugal fan. The materials of construction can affect weight, cost, sanitation, durability, maintenance, and appearance.
Materials of Construction
AirPro offers a wide range of materials to construct the fan wheel, airstream accessories, or the entire fan. Whether your application involves high operating temperatures, caustic contaminants, or explosive environments, AirPro has the most appropriate, highest-quality materials, including:
- All carbon steel grades
- All stainless steels
- Nickel-based alloys (625, C22, C276, etc.)
When our engineers are working on a consultation to determine and design the right fan for your application, they will specify the best materials for your unique situation. It’s not possible to detail every choice or combination here, but instead we will cover two types of preferred fan material as an example.
We often build our fans using different types of aluminum. While not used to build the entire fan, aluminum can be used to build some of the most critical fan components – the wheel and housing.
It is important to note that heavy-duty construction includes size and scale, as well as materials of construction, features, and accessories. We build our fans to work hard and last for years!
Aluminum Fan Application Example
Spark Resistant Construction: Spark Resistant Construction (SRC) is the technical term for industrial fans classified as explosion-proof. Spark Resistant Construction including Aluminum is an AMCA requirement or recommendation when dust, fibers, gases, vapors, or liquids could cause an explosion in the case of any kind of spark.

Stainless Steel Fan Application Examples
Food & Dairy Processing: The majority of dairy and food processing applications require stainless steel fans. For some, only the fan airstream parts are stainless, while others dictate the entire fan be stainless steel, including the motors and safety guards. Induced Draft Fans, often used in Dairy applications, process the hot air at the outlet of the dryer using 304 Stainless Steel airstream parts (APIC).
Corrosive gases: These are common in applications for biomedical, pharmaceutical, fume exhaust, and many other industries. Depending on the corrosive properties of the gas stream, the industrial fan can be built with an epoxy coated carbon steel, stainless steel, titanium, or a nickel alloy.
Scrubbers: Scrubbers commonly require fans to handle caustic materials. These fans are frequently built with 316 Stainless Steel materials and other alloy options.
