Backward Inclined Centrifugal Ventilators

Product Image

Backward Inclined Centrifugal Ventilators are available with three wheel designs. Airfoil blades are the most efficient with the lowest sound levels. Curved blades are idea for high-volume, low-pressure applications. Single thickness is best suited for airstreams with light material. Two fan lines, General Purpose and Square Fans, utilize backward inclined wheels.
