Description
The Armstrong International D502278 is a manually adjustable air vent used in a variety of HVAC systems to regulate airflow. Its orifice size is 5/32 inches, and its connection is a 3/4 inch National Pipe Thread (NPT). Usually, the vent is placed directly to the ceiling or wall or fitted within ductwork. You may control how much air enters or exits a room by setting the damper, which helps to maintain acceptable interior temperatures and enhances air quality. When air builds up in the system, the air vent causes it to rise to its highest position. By letting the trapped air out, the D502278 vent avoids airlocks, lowers system noise, and preserves ideal flow.
