Baxi Main Potterton 248043 Automatic Air Vent (AAV) Boiler Vent

The Baxi 248043 Automatic Air Vent (AAV) is a replacement boiler component suitable for selected Baxi, Main and Potterton boilers.

The automatic air vent releases trapped air from the central heating system, helping maintain proper water circulation, improve efficiency and reduce unwanted noise within the boiler and heating system.

A worn or faulty air vent may cause airlocks, circulation problems, noisy operation or poor heating performance. Replacing a leaking or damaged vent can help restore reliable boiler operation.
