External fans

In many branches of the modern drive technology industry is where frequency-controlled electric motors are found. Frequencies can get close to zero and the normal ventilation of the motor does not provide adequate cooling and thus cannot be guaranteed.

We offer Force ventilation units FBI in the sizes 56 - 560. These units consist of a special axial external driven fans that are integrated in the external fan cowl in order to protect the drive.
