DW Air Release 11/4

Deep Well Air Release 1-1/4″
This Deep Well Air Volume Control prevents tanks from becoming air bound by maintaining proper air volume. Float operation opens the air valve on water level drop (increase in tank air), and permits air to bleed from the tank to the atmosphere as the tank refills. Internal parts are constructed of brass to minimize corrosion. High impact plastic body is resistant to mechanical damage and corrosion.
