Overview
The Worcester Bosch automatic air vent is a pressure safety mechanism in the central heating unit. They work by using buoyancy to release an accumulation of air. As water circulates through the heating and cooling system, a float within the automatic air vent opens or closes depending on the water level. If the system contains only water, the float will be pushed to the top and the vent will be closed until the water level drops.
- Comes with O-ring and Clip
- Fits a number of Worcester appliances
