Large Axial Fans (all metal) also known as External Rotor Motor Fans are extensively used in Ventilation, Clean Room Technology, Refrigeration, Heat Exchangers, Welding Equipment, Condensing Units, Cold Rooms etc. These external rotor motor fans use minimal space and are hence used in conditions with space restrictions.

The Axial fan, the function of which is similar to a propeller, moves the air axially, parallel to the revolving motor shaft. The external rotor motor is integrated directly into the axial impeller, forming a compact axial fan unit.

Axial fans prove their reputation as space-saving wonders by moving air for hot or cold air exchange in a wide variety of devices and systems.
