Backward Wheel Industrial Blower

RXB & SXB Series

backward wheel industrial blower

The backward wheel industrial blower can be used for many types of applications but they are mostly typically employed for the displacement of air, for moving and conveying light materials and particulates.

The SXB Series industrial blower ranges in sizes from 12¼" to 44 ½" and includes a square housing and a backward inclined wheel. Various volumes, pressures and class’ are available. They are made of mild steel construction and are capable of up to 50 000 CFM, 15” H20, & 650°F

The RXB Series industrial blower ranges in sizes from 22¼" to 44 ½" and includes a Scroll type housing and a backward inclined wheel. Various volumes, pressures and class’ are available. They are made of mild steel construction and are capable of up to 50 000 CFM, 15” H20, & 650°F

How it Works

backward wheel industrial blower

A central shaft, about which a set of blades are connected to, is linked to and driven by a motor. Air is drawn into the fan near the shaft as the impeller rotates. As it turns, air is blown at right angles to the intake of the fan and is spun outwards to the outlet by deflection and centrifugal force.
