Spirotherm 3/4" Spirovent Jr. High Temperature Vertical Air Eliminator (Threaded)

Unlike conventional air eliminators or air scoops, the Spirovent 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 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. Air problems become a thing of the past. Features High temperature design for solar applications (“HT” models only)  Maintenance free.  No venting required.  Vent head is designed to stay dry. Dirt and leak resistant.  Quiet operation.
