Worcester Bosch Automatic Air Vent 87185050140

The Worcester Automatic Purger is a genuine air vent designed for use in the pump section of Worcester Bosch heating systems, including Greenstar, RD Series, Novatherm, and Greenstar ErP boilers. This central heating safety device automatically releases built-up air as the system operates, helping to maintain reliable performance and correct appliance operation. The vent uses a float mechanism that responds to water level: as water flows through the system, the float opens or closes the vent accordingly. When the system is full, the float rises to the top and the vent closes, remaining sealed until the water level drops again. The unit fits directly onto the expansion vessel and is supplied as a brand-new Worcester product, covered by the manufacturer's guarantee. This component supports efficient operation, long-term durability, and manufacturer-approved system protection, contributing to dependable heating and hot water performance.

The purger is compatible with a range of Worcester Bosch boiler models and is sold as a genuine replacement part to help maintain optimal system function.
