The Potterton automatic air vent is a pressure protection mechanism in the central heating unit. It works by using floatation to release built-up 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 contains no air, the float will be pushed to the top and the vent will be closed until the water level drops.

A Potterton brand replacement part, this 3/8" automatic air vent can be used in Combi, Puma and Ultra 2 boilers.  A central heating safety device, the automatic air vent releases built up air. As water flows through the system, a float opens or closes the vent depending on the water level. When the system is full the float is pushed to the top, closing the vent until the water level drops.
