Application
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.
