Honeywell EA122-AB Automatic Air Vent with Adaptor

The Automatic Air Vent EA122 is designed for heating systems and closed-circuit hot water systems to efficiently expel trapped air as the system fills with water. By removing air quickly, it helps prevent airlocks and supports optimal system performance. The vent can be installed on the positive pressure side of the system and includes a built-in vacuum break to aid the release of air bubbles. An integral stop valve allows easy cleaning and maintenance without draining the system, minimising disruption. The expanding disc beneath the cap creates a tight seal to prevent leaks and maintain system integrity. The EA122 provides a reliable solution for maintaining the performance and longevity of heating and hot water installations.

The device is suitable for heating and non-potable hot water systems, though it is not intended for potable water. The vacuum break on the bottom helps prevent air locks and facilitates the release of trapped air, while the integral stop valve enables servicing without draining the system. For practical installation, the vent is designed to be fitted on the positive pressure side of the system and should be placed in an accessible area for visibility and servicing.
