At AirPro, we take pride in designing and manufacturing custom fans tailored to our customers’ specific needs. The fan pictured in the video is still in production: but this gives us an opportunity to highlight some of the specialized features we integrate into our custom fan designs. AirPro designed this particular fan for an API 673 application.
Application: High-Temperature
We produced this high-temperature burner fan with an efficient backward-curved design and a max temperature of 800°F. The custom design includes thermal insulation for a safe skin temperature and a heavy-duty fan base to prevent vibration.
We designed a high-temperature purge fan for this regenerative thermal oxidizer (RTO) system application. The purge fan blade profile is backward curved to process high airflow at medium pressures. Customized to handle high temperatures, the application called for inlet and outlet expansion joints, and 2” thick insulated housing and inlet box, and an Arrangement 8 direct-coupled drive motor.

Air and heat are two essential components of industrial process manufacturing. Air serves as the conveyor, and heat is a transformer. In applications using high-temperature blower fans, both processes are happening together or in close proximity. That means the fans in these applications need to be able to take the heat, and in many cases, accompany corrosive gasses.
The following plug fan was rebuilt for a US steel company that heat treats customer supplied castings for automotive companies. After this user’s fan from another fan supplier failed, AirPro was asked to produce a dimensional & functional match. AirPro’s engineers reverse engineered the “model fan” and produced a “match.”
