SPIROTHERM® VJV Series VJV100FT Spirovent Junior Microbubble Air Eliminator, 1 in, NPT, Brass

Noisy pipes, valves and other air-related noises are often accepted as the signs of a functioning system. Excessive pump noise, cavitation and cascading in terminal units are considered normal. But air in system water can cause corrosion, reduced efficiency, poorly heated or inadequately cooled rooms, accelerated component wear and on-going complaints. There is a device that will keep your system-free of air permanently. Less maintenance, quiet operation, fewer costs!. Unlike conventional air eliminators or air scoops, the spiro vent completely eliminates 100% of the free-air, 100% of the entrained air and up to 99.6% of the dissolved air in the system. Consisting of woven copper wire soldered to a copper tube, the patented spirotube creates a low velocity area in the spiro vent 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. Air problems become a thing of the past.
