Spirovent Large Air Eliminators

Spirovent Air Eliminators eliminate air from the system, increase component life and heat transfer abilities, reduse oxygen-based corrosion and pump cavitation, and eliminate annoying urgling, cascading, and other air-related system noises. They crub out 100% of the free air, 100% of the entrained air, and up to 99.6% of the dissolved air in the system.

Spirovent Dirt & Air Separators are combined units with unique construction that allows for the removal of both entrained air and dirt particles. The patented Spirotube, the core of the Spirovent units, causes dirt particles of all sizes to sink to the bottom of the unit and collect in the dirt chamber, eliminating any blockage concerns. The dirt can be flushed through the drain while the system remains fully operational. Flow always remains constant, without high pressure drop. There are no strainers, filters or replacement parts to get clogged.
