Air and Dirt Separator

Thrush’s Aar-O-Vent air and dirt separator is designed for corrosion protection in hydronic piping systems. The device uses a stainless-steel coalescing filter medium to separate air and dirt from water in systems that can cause damage to pumps, seals and valves. Features include a gauge tap on the inlet and outlet connections, a removable bottom cover for cleaning the coalescing medium, and a blow down valve for flushing collected sediment. Available sizes for the separator range from 1.5- to 24-inches.
