Caleffi 502115A MINICAL™ Automatic Air Vent with Check Valve, 1/8" MNPT

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

The check valve on the 5021 series allows for easy replacement of the air vent without purging the system.
