Air & Dirt Separators

Air and Dirt Separators

Air & dirt separators are designed to eliminate entrained air and separate debris associated with start-up and maintenance of any hydronic system. The design incorporates a skim valve, used to eliminate floating debris, a removable end cover for coalescing medium access, and an air vent to automatically release air from the separator.

WVA Air & Dirt Separators

Air separators are typically used in hydronic heating and chilled water piping systems. WVA air & dirt separators are built with a removable cartridge and to ASME code. ASME code models with non-removable cartridge and non-ASME code models are also available.
