Description
The Amtrol 443 1-inch In-Line Cast Iron Air Purger removes trapped air from circulating water lines to maintain steady fluid movement within hydronic heating equipment. Its internal separation chamber directs entrained air upward for discharge while allowing water to continue through the piping circuit without interruption. The purger is installed along supply lines in boilers, radiant heating assemblies, and hydronic HVAC systems where air elimination is necessary for balanced circulation and heat transfer. Continuous air removal assists with the reduction of flow restriction, minimizes noise within piping networks, and improves circulation efficiency throughout closed-loop heating operations.
