Air Release Vents
Air release vents, also called hydronic air vent valves, connect to high points of hydronic HVAC systems and help to prevent air locks by venting unwanted gases. They are commonly used to vent the bulk of the non-condensable gases while air separators can filter out the smaller, entrained air bubbles that do not collect in the high points of the system.
