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.

Forced - Blower - Integrated  (short and simple FBI)

 

In addition to our standard series of Force ventilation fan units which are availabe in short delivery times,  we supply units specially designed and produced for original equipment manufacturers (OEMs) as well as for retrofitting to all electric motor brands on the market.

 

With reduced motor speed due to frequency operation , our forced ventilation fans increase efficiency and service life of your electric motors.
With Speeds above the synchronous motor speed, forced ventilation fans are used to reduce noise levels.

 

We are also happy to manufacture external fans according to your specifications. With our inquiry sheet you can simply send us your dimensions.

Contact us by e-mail or phone for the design of your external fan unit. Our technical sales team will be happy to assist you with any questions around our products.
