- • Best for: Small bathrooms, toilets and ensuites needing automatic moisture control
- • Not ideal for: Large wet rooms or commercial washrooms requiring high-capacity extraction
Delivers steady extraction at 78 m³/h while operating quietly at 26 dB(A). Runs on a 240V motor consuming just 7W, with humidity activation and an adjustable 2–30 minute run-on timer.
Automatic moisture control – With humidity sensor and humidistat
Humidity sensor monitors relative humidity and triggers operation when the set level, between 60% and 90%, is reached. Electronic control keeps the fan running until the target humidity has been lowered.
Prevents condensation and mould by switching the fan on automatically when needed, removing the guesswork after showers.
Quiet running – Thanks to low-noise design and efficient motor
Aerodynamic airflow path and an efficient 240V motor achieve extraction while keeping sound down to 26 dB(A). Low power draw of 7W contributes to smoother, quieter operation.
Suitable for installations near bedrooms or open-plan areas, where minimal appliance noise matters to household comfort.
Energy-saving operation – With 7W motor and adjustable run-on timer
Low power consumption limits electricity use during continuous operation, and the run-on timer can be set between 2 and 30 minutes to control post-use ventilation. Requires mains switched live, permanent live and neutral connections.
Keeps running times short while ensuring adequate extraction after use, helping to reduce running costs and wasteful over-ventilation.
