Vaillant Air Vents

Vaillant Automatic Air Vents also called AAV's, or Air Admittance Valves are a device often fitted internally to
Vaillant boilers which allow air to be discharged automatically from the boiler and or pipework systems. Air within
boilers and plumbing systems can cause problems such as excessive noise and poor thermal efficiency.
All our Vaillant Automatic Air Vents are new and genuine manufacturer spares.
