Air Admittance Valves

The AirSure Admittance Valves (AAV) allow air to freely enter the sanitary pipe work system and prevents the escape of foul gases into the building. They are suitable for 32-110mm waste and soil pipes.

This product is suitable for domestic and commercial applications.

The 32mm, 40mm and 50mm air admittance valve provides a universal connector for waste pipes, and the 82mm to 110mm air admittance valves are ideal for soil pipe systems.

When installed into sanitary pipe work systems, AirSure air admittance valves will prevent the loss of water from trap seals due to induced siphonage.

Each AirSure product is manufactured from high gloss white plastic that provides a modern, clean aesthetic look. Every product is individually tested and numbered prior to despatch thereby ensuring that the end user can install the AirSure range with added assurance and confidence.

They also carry the British Standards Institution (BSI) Kitemark (KM512474) as having met the performance requirements of BSEN12380 : 2002 and have been designated with an A1 rating.
