For the axial fans, protection flaps are available.
With these weather protection flaps the ventilators are protected against weather influences such as rain, snow, wind. Furthermore, the housing is protected from rain and wind when the ventilator is not running.
Application:
Blow-out protection grilles are available from stock for the axial fans in the add-on version. These can be screwed onto the discharge flange or onto the mounting ring.
This prevents the fan from reaching into the running fan in order to comply with the Machinery Directive in conjunction with DIN EN ISO 13857.
