Centrifugal Fans

Comet Fans’ range of centrifugal units includes fans with housing, plug-fans and open/free-running impeller fans.

Backward-curved, forward-curved or flat blade impellers are available on all series and can be manufactured from carbon steel, stainless steel or aluminium alloy, which allows Comet to offer the most suitable solution for environmental, mechanical, or noise requirements.
