  • All models available with housing 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 promote long equipment life.
  • Blower housings can be rotated in 45° increments to provide increased configuration flexibility in the field.
  • Removable inlet & drive side plates allow for removal of blower wheel or motor, or shaft and bearings on belt driven models, without disconnecting inlet or discharge connections.
  • Inlet side support assures a minimal vibration housing.
  • All fans receive a mechanical run test to ensure proper balance and alignment before shipping.
  • Belt driven models include heavy duty, grease lubricated, self-aligning, cast iron, and pillow block bearings selected for optimal performance.
  • Fan shaft on belt driven models is turned, ground, and polished and receives a high-quality rust preventative coating before shipment.
  • Arrangement 8 units come standard with shaft/coupling guards.
  • Arrangement 9 and 9CB units come standard with belt guards.
  • Arrangement 10 units come standard with weather cover.
  • All models are also available in aluminum or all stainless steel construction.


  • Multiple Wheel Selections: A shrouded wheel is standard on all models and series. An optional, open, radial wheel is available on sizes 7 through 21, in series 18, for applications where material is being conveyed through the blower. Each size and series is available in multiple widths from 50% to 100%, in 5% increments, to deliver the exact performance you need with a direct driven blower. (Contact our sales office, for your area, for this option). Complete design flexibility.
  • Rugged Construction: Housings are 10 or 7-gauge steel depending on model and series, 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.
  • Rotatable Housings: All models have housings that can be reversed and/or rotated in 45° increments in the field. However, open wheels cannot be reversed. Allows for field conversion without replacing the blower.
  • Ease of Maintenance: Replacing a wheel, motor, or shaft and bearings on belt driven models, is easily accomplished without disturbing the inlet and/or discharge connections. It minimizes extended downtime.
  • Quality Components: All belt driven models have self-aligning, cast iron, grease lubricated, pillow block bearings sized for a minimum 150,000 hours average life. All fan shafts are turned, ground, and polished and are coated with a high-quality rust preventative before shipment. Long dependable service.
