Benefits

Increased Efficiency: Airfoil wheels provide the highest efficiency of all centrifugal fan designs. The static efficiency of an airfoil wheel versus a backward inclined wheel can easily exceed 10%. This benefit results in lower brake horsepower consumption and a reduction in sound levels of 2-6 dBA. Less expensive to operate and quieter.
Multiple Wheel Selections: Each size and class is available with two airfoil wheel types and multiple widths from 50% to 100%, in 5% increments, to deliver the exact performance you need with a direct driven blower. Complete design flexibility.
Rugged Construction: Fan frame is heavy gauge steel with bracing to prevent pulsation at all conditions. Less field problems.
Quality Components: Belt driven models have self-aligning, cast iron, grease lubricated, pillow block bearings sized for a minimum 150,000 hours average life. Fan shaft is turned, ground and polished and is coated with a high quality rust preventative before shipment. Long dependable service.
