Safe, reliable belt drive centrifugal fans Ideal for use in average length and average resistance duct runs.
An aluminum, backward-inclined centrifugal wheel generates high-efficiency and minimal sound. Matched to the venturi for maximum efficiency, each wheel is robotically welded and statically and dynamically balanced for long life and quiet operation.
NEMA-1 switch is factory mounted and wiring is provided from the motor as standard (other switches are available). All wiring and electrical components comply with the National Electric Codes (NEC) and are either UL/cUL Listed or Recognized.
