Intermittent Fans - Centrifugal

For use in residential applications

Intermittent extract fan - Centrifugal

Ideal for air-extraction in bathroom and small premises. A powerful extract fan, designed to overcome the resistances of long ducting systems. Units can be wall/panel and ceiling mounted: designed for surface or flush (plasterboard) installation.


Humidistat-timer - The fan is provided with an electronic circuit having a humidity sensor on board (adjustable from 50% to 95% RH) and a timer, adjustable from ± 1’ to 25’. Operation: when the percentage of relative humidity is higher/lower than the pre-set threshold, the fan is automatically activated/deactivated. After switching off, the fan continues to run for the pre-set period of time.
