Blower WheelsNOTE: For propellers (props or fan blades), see Propellers page. There are 6 basic types of blower wheels used in industrial blowers. They are:
Type 1, Shrouded Radial Blade blower wheels are designed to deliver higher pressures for pressurizing, blow-off systems and long duct or pipe runs.
Type 2, Open Radial Blade with Back Plate blower wheels are designed for conveying powdery or granular material and long stringy paper trimmings or fibers.
Type 3, Open Paddle Wheel is primarily for conveying
powdery or granular material.
Type 4, Backward Inclined blower wheels are available with a flat blade design or a more efficient airfoil design blade where each blade has a cross section similar to an airplane wing. These wheel types are commonly used for general ventilation, forced cooling at higher pressures and in dust collection systems where the fan is on the clean air side of the dust collector.
Type 5, Forward Curve Multi-vane blower wheels are for moving large volumes of air at lower pressures. Typically selected for general ventilation or forced cooling at slower speeds.
Type 6, Backward Curved Radial blower wheels are a modified version of the Open Radial Blade wheel. It is designed to expand the performance ratings of open radial bladed wheels in some direct driven fans. In some cases, it can be used to convey granular material but should not be used to convey powdery or stringy material.
