Chicago Blower Fans
Airfoil SQA Square Fans
We are proud to be one of the world's leading centrifugal fan suppliers and our SQA Square Fan is our pride and joy. The SQA Square Fan is Chicago's most popular fan because it fulfills most commercial, and general industrial air moving needs. With its airfoil wheel and square housing design, the SQA is efficient, economical, and versatile. It is also quickly available through Chicago's Quick Ship Fan program. "Packaged" fans, those furnished with motor, V-belt drive, belt guard, and other options, are factory aligned, run tested, and shipped ready to install. By eliminating job site assembly, the packaged SQA fan can substantially reduce overall installation costs.
Pressure Blower D38 Cast Aluminum
Chicago castings blend aluminum with high-strength alloys to create strong, corrosion-free housings and wheels ideal for adverse industrial environments. Aluminum also stands up to sub-zero ambients without material deterioration. Since aluminum is non-magnetic and non-toxic, Chicago's cast aluminum pressure blowers are recommended for both electronic and food related applications. The non-sparking properties qualify Chicago's cast aluminum pressure blowers for AMCA spark resistant construction, earning an AMCA Type B spark resistant rating.
Packaged Forced Draft (PDF 4)
Initially developed 30 years ago for packaged boiler systems, Chicago's Packaged Forced Draft fan has earned a reputation as the industry standard. The PFD is a compact, direct-connected, airfoil-bladed fan offering exceptional reliability. To afford the highest efficiencies throughout the performance range, there are three wheel diameters available for each fan size. Fan and wheel width can also be varied to obtain maximum performance. For systems design versatility, seven standard discharge positions can be specified in each rotation.
