Thrush Air Separators

Sizes range from 1.5” to 6” Rated for 175 PSIG working pressure

Size range from 8” to 16” Rated for 150 PSIG working pressure

Even minimal amounts of air and dirt in a hot water system can cause major issues affecting efficient operation, maintenance costs, and corrosion. The Thrush Aar-O-Vent® air and dirt elimination technology has been independently proven to remove:

  • 100% of free air
  • 100% of entrained air
  • 99.7% of dissolved air
  • 99% of dirt particles as small as 17 microns 

As a result, your hot water systems can operate at peak velocity with virtually no corrosion or water flow issues. All models are designed and manufactured to ASME Section VIII, Division 1.
