Key Features
Low-Velocity Separation Chamber
An enlarged internal chamber drops fluid velocity so entrained air rises and heavier particulate settles, both continuously removed in service.
Blowdown Drain and Air Vent
An integral brass blowdown valve clears collected sediment and an automatic air vent discharges separated air without shutting the system down.
