  • Air Vents And Eliminators

    See all 7 items in product family.
    Air Vent Eliminators Allow For Heating System Maximum Efficiency.

    Air Vent Eliminators are constructed with a bronze body and stainless steel concentrator for long lasting durability. Conventional automatic air vents installed in Hydronic heating systems can leak and cause inefficient system operation. To effectively eliminate air from system without bleeding, air bubbles need venting. Honeywell SuperVent purges air through no clog vent assembly controlling dirt and debris to minimize air vent fouling. 360° adjustable collar ring provides installation flexibility. Concentrator eliminates gurgling noise. Threaded connections allow tight fit. Connection types are Female and Sweat . Color is Bronze . Available sizes are 9 in. L x 6.5 in. W x 4.5 in. H, 9.5 in. L x 4.75 in. W x 2.88 in. H and 10.25 in. L x 7.25 in. W x 4.5 in. H

  • Enhanced Air Separators

    See all 4 items in product family.
    Bell and Gossett Enhanced Air Separators Are Ideal For Residential, Institutional And Light Commercial Applications.

    These air separators are engineered to remove entrained air from hydronic heating and cooling systems, providing superior air removal compared with other devices. Enhance air separators are built to last using rugged two-piece cast iron body and cap construction. Internal parts are all stainless steel. Vent has a brass body and non-ferrous internals. These air separators are easy and convenient to install; requires no minimum pipe run. Features straight or angle pattern installation capability. Usable for systems with either steel compression or diaphragm expansion tanks. Includes a removable and replaceable 3/4" high capacity vent.
    How it works:
    As system fluid enters through the inlet, (either straight or angle) the diffuser distributes flow evenly across the stainless steel, wire brush-like medium. Air bubbles, even micro air bubbles, stick to the brush filaments. Trapped air rises above the diffuser through a baffle where the air is then released through an opening at the top. De-aerated water then goes back into the system.

  • Taco® Tank Drainers

    See all 3 items in product family.
    Taco® Tank Drainers Provide Effective Air Control In Hydronic Systems.

    Tank fittings maintain adequate air cushion to provide sufficient pressurization against all fluctuations of water volume. Tank drains maintain collected air within the pressure tank and allows air to pass freely into the tank. Restricts gravity flow of water between the tank and the system, resulting in lower tank temperature that minimizes re-absorption of air. Includes a single handle shut-off.
