Saunier Auto Air Vent (Aav)
The automatic air vent is a pressure safety measure the central heating unit. They work by using buoyancy to release accumulated air. As water flows through the heating/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.
