COLASIT radial fans

COLASIT radial fans are used wherever a greater pressure increase is required for the same air volume compared to axial fans. The air is drawn in axially, deflected through 90° by the rotation of the radial impeller, and blown out radially.
Casings and impellers are available in a range of different materials while drive motors have various efficiency classes to choose from. 

The radial fans are also available in an ATEX-compliant design for zone 1 (category 2) and zone 2 (category 3).

The air volumes of COLASIT radial fans range from 150 - 132,000 m3/h with pressures from 50 to 7,000 Pascal.

The latest product line CMVpro sets new standards in the field of efficiency of plastic fans and reduces your operating costs by up to 15% compared to the closest competitor.
