Filter installation

  • First fit the filter to the ventilator. Make sure the filter covers the ventilator housing and the rubber seal all the way round.
  • Then press the ventilator and filter into the pipe.
  • If you have installed correctly, the rubber seal will hold the ventilator properly in place in the pipe without having to use screws.


We provide a 10-year warranty for our thermostat bulb.
