This Baxi pressure switch is designed for use in Performa, Main Combi/ Combi HE, Main HE, Combi and System IE boilers.
A vital safety device, an air pressure switch ensures the boiler fan is working correctly and prevents a build up of toxic gases with no means of venting them in case of a fan failure.
The unit’s PCB closely monitors the air pressure switch to ensure it’s fully functional before firing the system up, keeping the appliance from starting without the presence and operation of key safety features.
