Vent-Axia 472318 Deluxe Quick Internal Fit Wall Kit White 100mm
The Vent-Axia 472318 Deluxe Quick Internal Fit Wall Kit is designed to simplify and improve 100mm through-the-wall ventilation installations. Suitable for a wide range of domestic and refurbishment projects, this innovative wall kit allows complete installation from inside the building, making it ideal for high-rise applications where external access may be difficult or costly.
Designed for use with 100mm extractor fans, the kit includes a low-resistance external grille and protective shroud to help prevent water ingress while maintaining a clean external finish. The telescopic tube design adjusts to suit wall thicknesses between 225mm and 390mm, providing a secure and installer-friendly solution.

Installer-Friendly Design
The Internal Fit Wall Kit reduces installation time compared to traditional flexible duct methods. There is no need to fit external grilles from outside the building or secure flexible ducting with jubilee clips. Once a 117mm core hole has been prepared, the kit simply pushes through the wall from inside the property, while spring pins secure the external grille in place.
The flexible internal flange also helps accommodate uneven internal wall finishes for a cleaner installation result.
Suitable for Modern Building Regulations
The external grille provides a free area greater than 90% of the duct area, making the wall kit suitable for continuous running ventilation systems as well as intermittent extractor fans.
Optional Backdraught Protection
Optional backdraught shutter versions are available to help prevent cold draughts and gusts of air entering the property through the wall kit. This is particularly beneficial when used with intermittent extractor fans.
