Aerodynamic single surface blade shape of backward curve wheel offers alternative selction points to the Airfoil wheel and also provides stable operation from wide open to closed-off. Square Fans incorporate non-overloading BI impeller desings: the motor can be sized for the operating horsepower of the fan and not oversized, thus increasing motor efficiency.net/quality.

Three different wheel designs on CB SQB Square Fans provide the widest choice in applications suitability, efficiency, sound, and cost.industrialblower. Typical uses include pneumatic conveying, product drying, process cooling, and exhaust on clean-side of dust collection systems.industrialblower. This feature allows maximum brake horsepower calculation and motor selection that prevents electrical system overloading even if system pressure changes. Arrangement 4 direct drive square Wiper Motor fans are ideally suited for a wide range of clean-air applications reuiring a tight footprint. Flat, single thickness backwardly inlined plades are suited for applications from clean air to those where dust and limited material is present in the airstream and where airfoil shapes are not recommended due to material build up that closes unbalance and vibration. now offers a new design of a centrifugal general ventilating fan - Square Fan, in direct drive and belt drive configurations.html

Industrial Blower Co. Heavy gauge spinning inlet with airflow diverter permits smooth air flow and close wheel tolerances.

Industrial Blower Co.net/fabricated-components. All of them feature the backward inlcinged non overloading horsepower chracteristic, where the horse power curve reaches a peak and then decreases even as air flow increases.

True aerodynamic airfoil blade shape allows stable operation from wide open to closed off; ideal for clean iar applications such as building ventilation with variable air volume system control or clean industrial gas handling.

Some design features of the CB Square Fans include:

The following accessories are avilable:
 Clean-out door - available as a quick opening latch type door that swings open on hinges after cam levers have been turned, or flash bolted type with closely spaced studs to keep door securely sealed with Neoprene foam tape gasketing

Outlet damper - single or multi blade, parallel blade or opposite blade designs, manually operated or complete with mounted electric or pneumatic actoator, for on / off or modulating air flow control Inlet volume control with variable inlet vanes - external or nested in the inlet cone, for manual or automatic air flow control
Housing drain - tank flange furnished in scroll of fans with down blast discharge, half couplings in housing drive side on all other discharges

* High temperature fan construction with a shaft China Motor For Car Sunroof Manufacturers cooler assembly and high temperature paint
* Flanged inlet and outlet
* Stainless steel construction of SST 316, SST 304 or SST 347 stainless alloy are available for corrosive applications
