Overview
The Potterton automatic air vent is a pressure safety mechanism in the central heating unit. It works by using a float to release accumulated air. As water flows through the heating and cooling system, a float within the automatic air vent opens or closes depending on the water level. If the system is full of water, the float will be pushed to the top and the vent will be closed until the water level drops.
