Other setups are possible on request.
The standard versions of these units are powered with single-phase or three-phase alternating current (see motor technical data
sheet for more information). Other ventilation methods can be studied on request.
Radial electric fans incorporate a washable filter to prevent incoming particles from damaging the motor. This filter requires
regular maintenance (see subsequent sections). This type of fan can include, (as an option on request) an anemostatic relay
(pressure gauge) with a set of NC/NA contacts that open/close when the airflow is insufficient.
