Airfoil Blowers: Model SQAF

FEATURES:
  • All models available with multiple width housing, two airfoil wheel types and wheel widths from 50% to 100%, in 5% increments, to deliver the performance you need with a direct driven blower.
  • Continuous welded housings, instead of lock seams, eliminate air leakage.
  • Heavy gauge steel bases, with internal bracing, maximize rigidity and assure long equipment life.
  • Four discharge positions and two rotations available.
  • Available with AMCA Type C spark resistant construction. For AMCA Types A and B, see Model "SQBI" Backward Inclined Blowers.
  • Removable inlet & drive side plates allow for removal of blower wheel or motor, or shaft and bearings on belt driven model, without disconnecting inlet or discharge connections.
  • 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 and two support legs for shipping and mounting support.
BENEFITS:
Benefits of Model "SQAF" Airfoil Blowers are:

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.
