The Aar-O-Vent™ (patent pending) high-performance air and dirt separator is designed for corrosion protection and increased performance in hydronic piping systems. It uses a stainless steel coalescing filter medium to separate the air and dirt from the water in these 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 this separator range from 1½ to 24 inches, and larger. According to the manufacturer, the Model 720 high-capacity air eliminator provides the air elimination for this unit and will not allow air back into the system even if a vacuum occurs.
