The Simply Silent™ C4HTSR 4"/100mm extractor fan  effectively eliminates humidity, condensation and odours to improve air quality in bathrooms, shower rooms, cloakrooms and toilets. It uses advanced Ghost Air Movement Technology to deliver near-silent running. Suitable for wall, ceiling, panel and window fitting, C4HTSR range has two speeds selectable at install. To maximise customer choice, the C4HTSR comes complete with both square and round baffle covers in the pack.

C4HTSR is a Humidistat / Timer fan. This means that the fan can be activated by either reaching a threshold of humidity or via an external switch (such as a lighting circuit). The fan will continue to run until the humidity has returned to threshold level or for a  period (can be set between 30s and 30mins) after the Timer overun has elapsed (whichever is the longer).
