SQB Square Fan Applications
The SQB Type "B" 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" wheel is ideal for custom applied corrosion resistant coatings. The SQB is also suited for high temperature gasses and air to 650° F. For greater safety in explosive environments, spark resistant construction is offered. The versatile SQB Square Fan is furnished in 14 sizes in Arrangements 1, 9 or 9H and in three classes of construction.
