Centrifugal Fans

The centrifugal fans operates by throwing air away from the blade tips. The blade wheel are mounted in housing and the blades can be forward curved, straight, or backward curved.

centrifugal fan

Backward curved blades are generally more efficient but forward curved blades are more "self-cleaning" and should be used in applications with high dust-concentrations, or where materials are conveyed by the air.

The centrifugal fans are preferred before axial fans where high airflow rates and high static pressures are required.

Axial Fans

Tube-axial fans consists of propeller-shaped blades and a drive motors mounted in tubes. The fans are in general build to be implemented in the duct work.

Vane-axial fans are variations of the tube-axial fans with air straightening vanes added in front of or behind the propeller blades.

axial fan

A propeller-axial fan consists of a a propeller-shaped blade and a drive motor mounted on a flat frame. The construction is often build to be installed in a wall or located individually in the room.
