4" Spirovent Senior VSR400-MT Air Eliminator, Male Thread

Spirovent Senior VSR400-MT Air Eliminator eliminates air from the system, increases component life and heat transfer abilities, reduses oxygen-based corrosion and pump cavitation, and eliminates annoying urgling, cascading, and other air-related system noises. It has 4" Male Threaded connections.

The Spirovent Air Eliminator has unique construction that allows not only for the removal of entrained air, but also for the countless microbubbles. Consisting of a woven copper wire configuration soldered to a copper tube, the patented Spirotube creates a low velocity area in the Spirovent that scrubs the bubbles from the water. The air bubbles rise and collect in the air chamber before they are vented from the system via an integral automatic valve. The Spirovent VSR400-MT Air Eliminator scrubs out 100% of the free air, 100% of the entrained air, and up to 99.6% of the dissolved air in the system.

Commercial units are fabricated steel and available from 2" through 36" pipe size and flows to over 30,000 GPM.
