Potterton Automatic Air Vent 5122330

The Potterton Automatic Air Vent 5122330 is a replacement boiler component designed to release trapped air from within a compatible central heating system.

Fitted at the top of the boiler, the automatic air vent uses a float-operated mechanism to detect changes in water level. When air accumulates inside the vent, the float drops to open the valve and release the trapped air. As water returns and raises the float, the valve closes to prevent water escaping.

This component helps maintain proper system circulation and supports the efficient operation of the boiler.
