We designed this custom backward-curved tempering air blower on a skid with a 75 HP IEEE 841 (Institute of Electrical and Electronics Engineers) severe duty motor.
Backward Curved Fans
Backward Curved Models Now Offer Smaller Fan Sizes
We are excited to announce the expansion of our Backward Curved models to include fans with wheel diameters below 27 inches. Combustion Air and other Forced Draft applications often require fans designed for low airflows at higher pressures, and we have traditionally supplied our high-pressure blower models for these applications. But our customers started asking us for fans with lower horsepower requirements, and our product development team set out to expand our offerings with more efficient options.
AirPro Customer Story: We recently got some great feedback from one of our customers in the Powder & Bulk Processing industry on how AirPro managed the quote, order, & installation phases of their project which, incidentally, included a few hiccups.
AirPro received the OEM order for four tempering blowers built for a glass manufacturer here in our home state of Wisconsin. The fans are installed on the back end of the glass oven, providing supply air for the tempering process.
