Worcester Bosch 87161021200 air pressure switch

Product Description

This Worcester Bosch air pressure switch is designed for use in CBi Series 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. We carry over 300 of the most in demand parts in-branch and stock over 25,000 spare parts available for next-day timed delivery.
