Adapt-Air is the pre-assembled ducting to airbrick adapter set from Timloc that helps to meet Building Regulation Part F.

The cost-effective ducting to airbrick adapter kit is delivered pre-assembled, ready to fit straight out of the box – it saves time, reduces costs and minimises the need for external fitters, core drilling and specialist tools, when connecting to an internal fan to duct through to an external wall.

Adapt-Air has been designed to be built in as part of the brickwork package and terminates at an external airbrick, removing the need to use unsightly gravity flap vents and avoiding the unsightly re-works of cutting a hole through brickwork.


  • Use at:
    • Floor level voids
    • External walls
  • Suitable for round and rectangular rigid extraction ductwork from:
    • Bathrooms
    • WC cloakrooms
    • Utility rooms
    • Kitchens

  • The installed position and level of the set is determined by the extraction fan connections.
  • The set can be flush or project beyond the inner wall leaf to allow for the fitting of additional ducting or an extraction fan.
  • The cavity wall construction will determine most suitable option length kit required.
  • As with all through cavity wall components install a DPC cavity tray, with wall weep and stop ends, above the installed adapter set to collect any water ingress. – We recommend the Inter-loc 4 horizontal cavity tray and 1143 or InvisiWeep, the almost invisible wall weep.
  • Timber/Steel frame wall construction may require cavity barriers or intumescent collars.
  • Quantity will be relative to the number of extraction fans required by the project.
  • Ensure that the correct shaped set has been selected to suit the ductwork.
  • State the airbrick colour required.
