Caleffi 502610A Automatic Air Vent 1/8" NPTM

The Caleffi 502610A Automatic Air Vent 1/8" NPTM is used to remove trapped air in HVAC systems. Works by using a float that detects if there is air inside the system. When there is more air, the float goes down and the valve opens to let air out. The air is out, the float goes back up, making sure the valve stays sealed and fluid does not leak. This ongoing process makes sure that air bubbles are quickly removed from the heating and cooling pipes. The main advantage is that fluid moves smoothly, heat is transferred better.
