Description
Baxi 720777601 Air Vent Valve | AAV for Ecoblue, 600, 800 & Duo Tec
Ensure your heating system runs quietly and efficiently with the Baxi 720777601 Automatic Air Vent Valve. This essential component, also known as an AAV, is designed to automatically release trapped air from inside the boiler pump and heat exchanger circuit.
Air trapped in the system can cause noisy operation (gurgling sounds), reduce heating efficiency, and accelerate corrosion inside the boiler. If your current valve is leaking water or fails to vent air, replacing it with this Baxi part is the solution.
This valve is a direct replacement for the air vent found in the latest generation of Baxi, Main, and Potterton boilers, including the Ecoblue Advance, Baxi 600 & 800 series, and Duo Tec GA models.
