Honeywell Home Automatic Air Vent EA122

The Honeywell Home EA122 automatic air vent is suitable for heating systems and other closed circuit hot water systems that require efficient, automatic removal of air when filling with water. Fitted anywhere in the positive pressure side where air is likely to be trapped, the vacuum break on the bottom of the valve prevents an air lock forming and encourages air to be released.
