WF 150A-04 BB
The WF axial fan is designed for forced ventilation in indoor spaces. The model is intended for window mounting. It can be installed in rigid partitions with a thickness of 4–32 mm, walls, window frames with single glazing of 4 mm, or multi-layer glazing up to 32 mm thick.
The fan housing is made of ABS-plastic. The unit is equipped with automatic louvers that open a few seconds after being switched on. When switched off, the louvers return to the closed position. Thanks to the ball-bearing motor, the fan maintains its capacity and service life regardless of its orientation when installed in the window structure.
The operating speed is switched using the built-in pull-cord switch.
