Sime Air Vents

Sime Automatic Air Vents also called AAV's, or Air Admittance Valves are a device often fitted internally to
Sime 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 Sime Automatic Air Vents are new and genuine manufacturer spares.
