Direct-drive fans feature the impeller mounted directly on the motor shaft, removing belts, pulleys, and associated maintenance requirements.
This configuration improves mechanical efficiency by up to 5%, reduces vibration, and extends service intervals by eliminating belt tension adjustments and replacements.
They are available in axial and centrifugal formats—flow rates from 1,000 to 200,000 CFM at pressures up to 6 kPa—and can be paired with VFDs for precise speed control.
Compact footprint, sealed bearings, and premium motors make direct-drive fans ideal for HVAC, process ventilation, and dust collection applications seeking low maintenance and high reliability.
