Baxi 5137531 Air Pressure Switch

£33.20 ex. VAT

The air pressure switch Is a safety mechanism that checks the fan is working correctly. It ensures that, if the fan fails within the boiler, there would not be a build up of noxious gases with no means of venting them. The PCB closely monitors the air pressure switch to make sure it is fully operational before the unit is fired up, preventing the appliance from starting without one of its key safety instruments.
