This Honeywell Home automatic air vent with integral shut-off and leak protection includes an integral vacuum break, float housing, lid, float, seal can with expanding discs and valve seat seals. A central heating safety device, the air vent releases built up air. As water flows through the system, a float opens or closes the vent depending on the water level.
