MINICAL™ Automatic Air Vent - NA Market

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.
