Forced Ventilation Units (FBI)

In most areas in the modern electric drives electric motors controlled by y frequency inverter are used. At frequency ranges down to zero the self-ventilation is non-existing and thus a forced ventilation is required.

We offer our external forced ventilation units from frame size 56 up to 560. This forced ventilation unit consists of a axial driven fan which is integrated in a fan cowl for protection against damages.


In addition to our standard series which are available from existing stocks we supply also forced ventilation units customized to be assembled on all available OEM-motors.

Our company´s strength is the flexibility and the realization of our customer´s requirements.
