Food-Grade Cyclone Exhaust Fan

Paddlewheel Exhaust Fan

We designed this paddlewheel exhaust fan for a food-grade cyclone application. Basic features included a slip-fit inlet, outlet transition to a round slip fit, spring vibration isolators, and an Arrangement 1 belt drive with a unitary base. Making this fan food-grade required a full complement of custom components, finishes. and materials of construction, including:

  • 304 stainless steel on airstream parts and a tri-clamp ferrule drain
  • Bead blast finish of stainless steel parts
  • 3A (180 grit) polish of housing interior and wheel
  • Epoxy coating on the mild steel parts
  • Teflon shaft seal
  • Nitrile gasket material
  • Clean-in-Place (CIP) nozzles
  • Continuously-welded airstream interior

Specializing in material-laden air, the heavy-duty industrial exhaust paddlewheel fan pulls the heavier particulates out of the food processing airstream in the food-grade cyclone separator. It then feeds the air through the industrial air filtration system without compromising the integrity of the food being processed or the fan wheel.
