The Fan 1900 W100 bathroom fan is the perfect solution for your bathroom to effectively combat damp, unpleasant odours and mould. With a diameter of 100 mm and activation via the light switch, this powerful yet particularly quiet bathroom fan creates a pleasant atmosphere in the room. The bathroom fan operates at a remarkably low noise level of just 28 dB(A), with an air flow rate of 75.4 m³/h. Handling is extremely convenient, as the fan is activated directly via the light switch. Thanks to the integrated non-return flap, the exhaust air is reliably transported to the outside, while the ingress of outside air is prevented. Installation is also straightforward: Using simple standard tools, the fan can be attached to both the wall and the ceiling. The elegant and timeless design in the exclusive Bosch style fits perfectly into any bathroom and provides an aesthetic upgrade.
