Ideal automatic air vent is a safety device within the central heating unit. They work by using floatation to release an accumulation of 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 only water, the float will be pushed to the top and the vent will be closed until the water level drops.
Fits the Ideal domestic Mini C24, C28, S24 and S28
