Centrifugal Fans

Airfoil Plug Fans: Model CPAF

• All models available with two airfoil wheel types and multiple wheel widths from 50% to 100%, in 5% increments, to deliver the performance you need with a direct driven blower.
• Extended fan shafts extend the wheel through insulated oven walls up to 6” thick.
• Insulated plug boxes, up to 6” wide are available.
• Inlet bell for smooth air entrance into the wheel and maximize efficiency is standard on all units.
• Continuous welded housings are available.
• Heavy gauge steel fan frame and bracing, maximizes rigidity and assures long equipment life.
• Multiple lifting points for easy installation.
• Available with AMCA Type C spark resistant construction.
• All fans receive a mechanical run test to assure proper balance and alignment before shipping.
• Belt driven model includes heavy-duty, grease lubricated, self-aligning, cast iron, pillow block bearings selected for optimal performance.
• Fan shaft on belt driven model is turned, ground and polished and receives a high quality rust preventative coating prior to shipment.
• Arrangement 9 comes standard with belt guard, extended bearing lube lines and four- point motor adjustment base for proper belt tension.

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.
