Caleffi 502343A Air Vent (150PSI, 1/2in)

Automatic air vents are designed to remove trapped air that accumulates in heating and air conditioning systems automatically. Air removal enhances performance and life of a system by reducing the affects of:

• corrosion due to the oxygen
• pockets of air trapped in the heating emitters
• cavitation in the circulation pumps

Operating mechanism The air is vented by means of a stem mechanism protected against debris from outside. Chamber The height of the chamber for float movement is designed to collect high air volumes from water. Hygroscopic cap A safety hygroscopic cap automatically closes the air discharge in case of contact with water.
