An Experience
A good number of years ago I visited Pittsburgh for a long weekend with my wife. While there, we visited the Andy Warhol Museum. After turning 30, I found myself drawn to art museums—perhaps a promising sign of maturity. Before that, I had little interest in art, and even now I’m not entirely sure what caused this shift besides the passing of time. The Warhol Museum provides visitors with an up close and personal view of Warhol’s life as it pertains to his artwork. One interpretative exhibit resonated with me more than the others.

This fan is a critical component of a dual-fan scrubber skid, designed specifically for environmental remediation. The end-user deploys it at contaminated sites to harness heat which penetrates deep into the earth to release harmful toxins in vapor form. The fan provides powerful vacuum extraction, pulling these vapors through the scrubber system, where they are treated and safely released into the atmosphere.
With its rugged construction and unmatched functionality, this powerhouse fan is the ultimate solution for providing the pneumatic conveying air necessary for moving trim and scrap materials.

Introducing the ultimate workhorse for low volume pressurized lines—the BCLS 182 Arr 4 fan from AirPro. We built this fan to provide pneumatic conveying air for a trim and scrap handling system requiring peak performance and durability and engineered it to tackle low pressurized volumes while maximizing efficiency. Check out the key highlights:

The Other Guys
Sometimes researching a manufacturing company to purchase goods from exposes marketing language that conveys an air of having “arrived,” as if the brand operates on a higher plane. The implication is that owning their products grants access to this exclusive realm of rarified air. This approach can feel off-putting, though the specific reason for this reaction can be difficult to articulate—the undeniable sentiment it evokes just feels off.
In industrial settings, fans designated as explosion-proof require careful consideration of which components meet the criteria to ensure safe operation in combustible environments.
TodaToday, we spotlight a uniquely engineered swingout BIHS fan, custom-designed by our engineering team for an automotive plant in the Midwest. This fan features a quick-release access door positioned at 9 o’clock on the fan housing, with a flush interior surface that allows easy wheel access. Constructed with stainless steel AMCA C spark-resistant materials free of any silicone, grease-lubricated bearings, and precision laser cutting, it delivers exceptional efficiency and power without sacrificing durability and reliability. We also equipped this fan with a Formsprag backstop clutch to keep the wheel from rotating when not in operation.
The shipment of any industrial fan represents a crucial last step in the manufacturing process because the customer desires timely delivery and an undamaged product. In this video we explain AirPro’s two options for managing shipping.

In 2002, AirPro began with a toolbox and three engineers who faced many challenges—including welding: welding fell outside of our founders’ expertise. Because of this, our initial fan orders required partnerships with local weld shops, often resulting in quality below our standards. To address this, we hired a welder (who happened to be my uncle) and tasked our sales department with ensuring a consistent workload for him. Recognizing that welding expertise would drive our future success, we prioritized developing the best welders in the industry.
Tim Siverhus is no stranger to the industrial fan industry. This 20-year fan veteran has sold industrial fans since graduating from Minnesota State Mankato with a Bachelor of Science degree in Engineering. And, despite owning two industrial fan companies in Southern California, he still finds time to captain sailing yachts. But let’s not jump ahead.
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.
