This 100mm Airvent extractor fan is a smart and simple solution to improve ventilation in bathrooms, cloakrooms, or downstairs toilets. It features a 2615 rpm motor that delivers an extraction rate of 76m³ per hour. The fan is IP44 rated for use in bathrooms and cloakrooms, and is constructed from high-quality ABS moulding with a gloss finish for a practical and attractive installation. It is suitable for wall mounting with an appropriate kit and meets the requirements of Building Regulation Document F and L. The timer function operates with the room light switch: when the light is switched on, the fan comes on, and when the light is switched off, the fan continues to run for a pre-set time. Please note: the timer function requires permanent live, switched live, and neutral wires (3 wires excluding earth) at the fan position to operate correctly.
