Materials of Construction
Built for heat, corrosion, abrasion, and continuous-duty service, we match materials, structural design, & protective features to the needs of your application.
AirPro // Features
Industrial-Grade Fans & Blowers Designed for Continuous Operation
At AirPro, we focus on industrial customers who need centrifugal fans and blowers that run reliably in demanding environments. We design, build, deliver, and service heavy-duty equipment used worldwide across a wide range of industries, handling clean air, saturated air, and material-laden air and gases.
Heavy-duty construction is not just about making something thicker. It’s a full approach that considers size and scale, materials, wear features, and the accessories required for your specific duty. With decades of application-driven engineering experience, we build fans and blowers designed for long service life and built to hold up over time.
The Breadth & Depth Of Our Focused Product Line
While our range of expertise is vast, our focus is tight. Our products are designed with maximum reliability in mind, and that influences every aspect of our manufacturing process. We are innovative and possess unique expertise in a variety of industries, creating custom solutions for just about every customer project. After all, doing so is generally a requirement, as each application and installation has characteristics completely unique to its organization or environment.
Fans & Blowers Built for Your Environment
Material selection is a critical part of centrifugal fan design. The right materials affect corrosion resistance, durability, sanitation, maintenance requirements, weight, cost, and even the finished appearance of the fan.
AirPro offers a wide range of material options for fan wheels, housings, airstream components, and complete fan assemblies. Whether your application involves elevated temperatures, abrasive or corrosive contaminants, sanitary requirements, or hazardous operating conditions, our engineers help specify the best-fit materials for long-term performance. Available material options include:
- Aluminum
- Carbon steel grades
- Monel
- Nickel-based alloys, including 625, C22, C276, etc.
- Stainless steels
- Titanium
Because every application is different, it is not practical to list every possible material combination here. Instead, the examples below highlight two commonly specified fan material categories and the types of applications they support.
Aluminum Fan Application Example
AirPro builds fan components in a variety of aluminum grades when the application calls for it. While aluminum is not typically used for full fan construction, it is often used for critical components such as the wheel and housing.
As with any fan design, heavy-duty construction depends on more than material alone. Fan size, operating conditions, features, and accessories all contribute to long-term durability and performance.
Spark Resistant Construction (SRC)
Aluminum is commonly used in spark-resistant fan construction when required by the application. In environments where dust, fibers, gases, vapors, or liquids may create an explosion risk, AMCA spark-resistant construction requirements or recommendations may apply.
Spark Resistance Overview
Stainless Steel Fans 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).
Scrubbers
Scrubbers commonly require fans to handle caustic materials. These fans are frequently built with 316 Stainless Steel materials and other alloy options.
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.
Material Selection Is Application Specific
Choosing the right material depends on the full operating environment, including temperature, corrosion potential, sanitation requirements, abrasion, and safety considerations. AirPro’s application engineers evaluate these factors to recommend the best material combination for performance, service life, and cost-effectiveness.
If you are unsure which materials of construction are best for your application, AirPro can help you determine the right solution for your process and environment.
