The Built In Wall Fan is what the name implies, the unit is built into a brick wall making both the inlet and discharge side flush with the wall.
The fan characteristics are similar to the series Vitro9A and Vitro12A. Both models are speed controllable and reversible by means of an optional speed regulator. The speed regulator allows the air direction to act as an intake or extract fan and the speed to be regulated on both directions.
The louver shutters open automatically when the unit is switched on and close when the unit is switched off.
Two models are available 230mm and 300mm with a wall opening of 370mm x 370mm being the same for both models.
The 230 volt 50Hz motor is protected to IPX4
