We are proud to be one of the world's leading centrifugal fan suppliers and our SQA Square Fan is our pride & 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 jobsite assembly, the packaged SQA fan can substantially reduce overall installation cost.
