Mixed Flow Fans
Mixed Flow Fans

Mixed flow fans are more efficient than comparably sized inline tubular centrifugal and vane axial fans, operating at a lower sound level, reduced motor horsepower, and lower operating costs. Mixed flow inline fans are used for supply, exhaust, or return air installations indoors or outside.

QEID

Model QEID is the direct drive version of the QEI with the mixed flow wheel direct connected to the motor. The QEID has the same construction options as the QEI, but with better performance and higher efficiency by eliminating losses through belts, pulleys and fan shaft bearings. Plus, as a direct drive, the QEID has the added benefit of reduced maintenance by removing these same components. The design is more compact for space critical application.

  • 700 to 88,000 cfm
  • Up to 10 in. wg
  • Spark B and C resistant construction available
