CALEFFI 502015A Minical Series Automatic Air Vent

Automatic air vents are designed to remove the air that accumulates in heating and cooling systems without the need for manual intervention. This prevents harmful air that may compromise the life and the performance of the system which includes: corrosion due to the oxygen; pockets of air trapped in the heat emitters; cavitation in the circulation pumps; noise from air passing through the pipes. The accumulation of air bubbles in the air vent body causes the float to drop and thus the vent valve to open. The air vent functions correctly as long as the water pressure remains below the maximum discharge pressure
