The water that is used initially to fill a hot water heating system contains dissolved air. Make-up water added at a later time will similarly have a high air content. Heating this water releases the air and permits it to be circulated in the system, which must be vented. The purpose of an Air Purger is to continuously separate and collect any air from the water as it circulates so that it may be vented automatically by a float air vent without the necessity for frequent manual venting.

Standard Features:

  • Installed horizontally on main as close to boiler as possible
  • Tappings for installation of air vents
