The Fernco AirSure AAVs allows air to freely enter the sanitary pipe work system and prevents the escape of foul gasses into the building.

This product is suitable for domestic and commercial applications, and air sure provides several benefits to the user:

  • Removes the need to penetrate the outer roof shell
  • Prevents the loss of water from traps and seals
  • Saves on cost of additional pipes and fittings
  • Labour cost savings
  • Environmentally friendly - no foul gases emitted

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, Fernco air sure will prevent the loss of water from trap seals due to induced siphonage.

Each air sure 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 air sure 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.
