Reliance Brass Automatic Air Vent 3/8 in BSP

High quality automatic air vents for use in heating systems to vent air when commissioning a system. The device consists of a polypropylene float connected to a simple valve. When the build-up of air within the float chamber exceeds a certain level the float drops, opening the valve and releasing the air trapped within the chamber. As the air is released, water replaces it, and moves the float back into the up position, which closes the valve

Air Vents

Air vents automatically remove air and other incondensable gases from steam systems, reducing heat transfer and affecting steam temperature. They improve heat transfer, while saving energy, and maintain process performance where temperature is critical. Their use reduces corrosion and maintenance costs, promotes even heating and improves product quality.
