Fans

Our fans can be found anywhere there are people. We have a vast product range to meet virtually any application or requirement. Our fans can be used for heat recovery, for supply and/or exhaust air, and for the secure transport of explosive gases.

Our fans are available with AC or EC motors, which are external rotor motors with maintenance-free double-sealed ball bearings and a galvanized steel casing. Nearly every fan in our range has a swing-out design, making them easy to service and clean. All of our fans are extremely high-performance and high-quality. Our fans meet the requirements of the EU’s ErP Directive.
