Chicago Blower's SQB fan is regarded as a high performance, trouble free fan proven in a myriad of industrial applications. With its backward inclined fan wheel and square housing design, the SQB fan is efficient, economical and versatile. It is also quickly available through Chicago's Stock 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 SQB fan can substantially reduce overall installation cost. The SQB Type "B" fan wheel has backward inclined blades designed to handle corrosive or dusty airstreams. Typical applications include oven circulators, dust collector exhaust fans, fume exhausters and emissions control system. Since the blades are solid steel, the "B" fan wheel is ideal for custom applied corrosion resistant coatings. The SQB is also suited for high temperature gasses and air to 650°. For greater safety in explosive environments, spark resistant construction is offered. The versatile SQB fan is furnished in 14 sizes in Arrangements 1, 9 or 9H and in three classes of fan construction.
