The Worcester Bosch 87185050140 Automatic Air Vent is a genuine replacement component designed to remove unwanted air from your central heating system automatically. As air naturally accumulates in radiators, pipework and boiler circuits over time, it can create noise, reduce heating efficiency and cause cold spots because trapped air disrupts water circulation. This automatic air vent allows those air pockets to escape without manual bleeding, helping maintain smooth water flow, stable temperatures and efficient system performance.

This automatic air vent is compatible with Worcester Bosch Greenstar and RD series boilers that specify part number 87185050140 in their technical documentation. To ensure correct fitment and dependable operation, always verify the part number on your existing vent or consult your boiler’s service information before installation, as vent designs and connection sizes vary between systems and models.

Supplied ready for direct replacement, the 87185050140 Automatic Air Vent installs into the designated vent port and integrates with your heating system’s pipework when fitted by a qualified engineer. Choosing this genuine Worcester Bosch component helps maintain efficient circulation, reduce air-related noise and support dependable heating performance across compatible Greenstar and RD boilers.
