Spirotherm PJR000HA Vent Head (4.72 x 3.31 x 3.19in)

Vent Head for Jr. Series Air Eliminators PJR000HA

Vent head is designed to stay dry and is dirt and leak resistant. 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. Even the smallest micro bubbles coalesce and rise. Air is eliminated, component life and heat transfer abilities are increased; oxygen-based corrosion and pump cavitation are reduced; and annoying gurgling, cascading, and other air-related system noises are eliminated. Unique valve mechanism is guaranteed not to leak and cannot be shut off. Standard thread for vent pipe connection or pressure testing. Specially constructed air chamber to protect the valve mechanism from dirt. Sufficient volume to handle pressure fluctuations. Includes only the Spriovent Vent Head for Junior Series Air Eliminators Designed to stay dry Vent head is dirt resistant Vent head is leak resistance.
