Description
The Armstrong International D41790 Air Vent is a pressure-rated venting Unit used in HVAC systems to remove trapped air from hydronic heating and cooling circuits. It is applied in piping networks, boilers, and chilled water loops where accumulated air can disrupt circulation and reduce thermal transfer efficiency. The vent connects through 1/2″ female pipe threads and 3/4″ male pipe threads, allowing integration into existing line configurations while operating up to 150 PSI. It is typically positioned at high points in piping systems during maintenance or setup to ensure smooth fluid movement and balanced system operation.
