* without filter, using as outtake ventilation

Our new family of ventilation fans is primarily suited for industrial applications, above all in distribution boxes, server rooms, i.e. all places where permanent ventilation is needed for proper operation of the built-in devices. Our fans can be simply and quickly installed, without screws, by flipping ears.
The IP54 protection level of the fans (against raindrops and dust particles large than 10 μm) is ensured by extra thin filter inserts. The direction of the air stream can be selected by inversion of the fan.
For proper performance, the fans shall be installed in the lower third of the distribution box, exits protected by filter insert. Automatic ventilation can be provided by thermostatic control.
