Product Description

The Jet Automatic Air Vent (AAV) range has been designed for use in sealed heating systems to continually remove air during the initial filling and subsequent operation of the system. As water circulates around a sealed heating system, it begins to evaporate and separate after a period of time. If the air is left within the system, this can cause phenomena such as noisy pipework, cold spots at the top of radiators and an overall decrease in system efficiency. Jet’s Automatic Air Vent eliminates these problems by allowing trapped air to escape the system without the need for constant manual venting of radiators. This particular Jet Automatic Air Vent features an innovative vacuum break at the base of the valve to prevent an air lock forming and to encourage air to be released. The AAV also benefits from being supplied with a check valve; enabling the AAV to be removed from the system without the need for time consuming drain down - making it the perfect choice for professional installations.
