Amtrol 2" Air Purger, 1/8" Threaded Vent (125 PSI, Cast Iron)

Designed to separate air from water in a closed heating system so that it can be properly vented. Baffles inside the purger cause dissolved air to be separated from the water as it flows through the purger. The elimination of air improves the performance of the system and helps prevent harmful corrosion. Available in 1” through 3” sizes. Use with 700 Series Automatic Air Vents and Extrol® Expansion Tanks.
