The centrifugal impeller has backward-curved plastic blades that are pressed directly onto the motor and dynamically balanced as a unit. The fan is low-noise and highly efficient. It has a single-phase AC external rotor motor in a closed design, is maintenance-free and has built-in thermal contacts as well as sealed, low-noise ball bearings with long-term lubrication. The power is regulated by means of an electronic controller, step transformer or in two-stage operation with type DS 2/2 (accessory).
