Industrial fan designs are engineered to meet specific performance requirements while maintaining structural integrity. Different industrial fans applications have unique flow and pressure requirements. Application conditions also vary, with fans being subjected to high rotating speeds, corrosive materials, abrasive air streams, and extreme temperatures. The right fan choice is based on these application requirements and the environment in which the fan or blower will be used.
Fan and blower wheels are used in fans to produce air at high volume and low pressure. Air is discharged at 90 degrees out through the discharge of the housing. There are a variety of blower wheels or centrifugal impellers used in industrial fans and blowers. Here are the 8 basic types of wheels used in industrial fans and blowers:
Shrouded Radial Blade blower wheels are designed to deliver higher pressures for pressurizing, blow-off systems and long duct or pipe runs.
Open Radial Blade with Back Plate blower wheels are designed for conveying powdery or granular material and long stringy paper trimmings or fibers.conveying powdery or granular material and long stringy paper trimmings or fibers.
Open Paddle Wheel is primarily for conveying powdery or granular material.
Backward Inclined blower wheels are available with a flat blade design. 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.
Backward Curved blower wheels provide high efficiency and low noise. They are typically used for general ventilation, dust collection where the fan is on the clean side of the dust collector, combustion air, and drying.
Airfoil wheels incorporate a blade design with the cross section of an airplane wing. They are the most efficient design for moving large volumes of air. They are commonly used for ventilation, forced cooling at higher pressures, and on dust collectors, where the fan is on the clean side of the collector.
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.
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.
