Potterton 642236 Air Pressure Switch

£57.98 ex. VAT

The air pressure switch enacts safety checks which ensure the fan is fully functional. It ensures that, if the fan fails within the boiler, there would not be a build up of noxious fumes with no means of venting them. The PCB closely monitors the air pressure switch to make sure it is fully functional before the unit is fired up, preventing the appliance from starting without one of its key safety features.
