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.
