The Automatic Air Vent EA122 is suitable for heating systems and other hot water systems (not potable water) which require the efficient automatic removal of air from water. The vacuum break on the bottom of the valve prevents an air lock forming and encourages air to be released from water. The air vent can be fitted anywhere in the positive pressure side of the system where air is likely to be trapped.
