Ventilation fans

For OEM’s as well as for the electric motor repair industry motors we supply PPN and aluminum fans in sizes from 56 to 355. The ventilation fans are universally used for nearly all electric motor brands.

Within our plastic range, we offer PPN ventilation fans for temperature ranges from – 20 ° C to + 90 ° C and in Ultramide / Polyamide for ambient temperatures from – 30 ° C to + 170 ° C.
In the aluminum section, finished machined ventilation fans and unmachined ventilation fans are available.

Our ventilation fans are available with keyway or clamp. (Aluminium ventilation fans – unmachined with 10 mm raw bore for customers own processing.

 

For increased airflow and quiet operation we also offer ventilation fans with uni-directional axial wings in plastic or aluminum. Due to the pre-selection of different profiles and angle settings, individual air outputs can be achieved. The advantage over conventional ventilation fans is that they have very high efficiency with low power consumption and noise level.
The aluminum hub is manufactured to your specifications. Different airfoils and diameters allow outer diameters from 120 mm to 2745 mm.
The wings can be made in fibreglass , reinforced plastic as well as in aluminum. Operating temperatures from – 40 ° C to 110 ° C for aluminum up to 150 ° C / 245 ° C * (* – 60 ° C to 245 ° C depending on profile for aluminum fans)
