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: Housings are heavy gauge steel and are continuously welded to prevent leakage. Fan bases are 7 and 10 gauge steel with internal bracing to prevent pulsation at all conditions. Less field problems.
EASE OF MAINTENANCE: Replacing a wheel or motor, or shaft and bearings on belt driven models, is easily accomplished without disturbing the inlet and/or discharge connections. Minimizes extended down time.
QUALITY COMPONENTS: Belt driven model has 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.
