E121 Automatic Air Vents are ideally suitable for hot water heating systems, radiators. Inside the automatic air vent there is a floater which operates a lever according to the water level. When there is no water in the housing, then the floater opens the valve. Air can therefore be vented from the heating system during filling. When the heating system has been filled, the inflowing water closes the valve and the vent is shut off. Water usually contains oxygen which bubbles off during operation of the system and collects at the highest point. The automatic air vent must therefore be fitted at the air collection position
