Vent-Axia 472319 Deluxe Quick Internal Fit Wall Kit Brown 4" (100mm)
Product Description
The Vent-Axia 472319 Deluxe Quick Internal Fit Wall Kit is an innovative 100mm (4-inch) ventilation accessory designed to simplify through-wall installations. Finished in brown, this adjustable wall kit can be installed entirely from inside the property, making it particularly suitable for high-rise buildings, flats and residential refurbishment projects where external access is difficult or costly.
Designed for use with compatible 100mm extractor fans and ventilation systems, the kit features an adjustable telescopic duct that accommodates wall thicknesses from 225mm to 390mm. Its quick-fit design eliminates the need for external grille installation from outside the building, helping reduce installation time and avoid the additional expense of scaffolding in suitable applications.
The integrated external rubber seal and protective shroud provide a neat finish by covering irregularities around the external wall opening. The seal also helps protect against water ingress, while the low-resistance external grille supports efficient airflow for both intermittent and continuous ventilation systems.
Ideal for professional installers and property maintenance teams, the Vent-Axia 472319 offers a convenient and practical solution for 100mm through-wall ventilation installations.

Quick Installation from Inside the Property
The Vent-Axia 472319 is specifically designed to simplify through-wall ventilation installations where external access is restricted. The complete wall kit can be fitted from inside the building, making it particularly useful for upper-floor flats and high-rise properties.
Following preparation of a suitable 117mm diameter wall opening, the kit is inserted from the inside. Spring pins secure the external grille, while the protective shroud deploys around the outside opening to provide a neat finish.
This installation method can reduce the need for external access equipment and helps installers complete ventilation upgrades more efficiently.
Adjustable Telescopic Ducting
The integrated telescopic duct adjusts to suit wall thicknesses between 225mm and 390mm. Once positioned at the required length, the tubes lock into place to provide a secure installation.
Unlike traditional installations using flexible ducting, the quick-fit design reduces the need for separate duct connections, jubilee clips and external grille fixing.
The flexible internal flange also helps accommodate minor irregularities in the internal wall surface.
External Weather Protection
The Deluxe Internal Fit Wall Kit incorporates an external rubber seal and protective shroud designed to improve the appearance and weather resistance of the finished installation.
The rubber seal helps reduce water ingress around the external wall opening, while the shroud conceals minor break-out caused during drilling. This creates a cleaner and more professional external finish without requiring installers to access the outside of the building.
Low-Resistance Ventilation Grille
The supplied external grille is designed to minimise airflow resistance. Its free area is greater than 90% of the duct cross-sectional area, making the kit suitable for compatible continuous-running and intermittent ventilation systems.
The wall kit can also be used for suitable passive ventilation applications where a 100mm wall connection is required.
Backdraught Shutter Options
Selected models within the Vent-Axia Internal Fit Wall Kit range are available with backdraught shutters. These help reduce unwanted draughts entering the property when an intermittent extractor fan is switched off.
Check the exact model specification if a backdraught shutter is required, as this feature is not confirmed as included with product code 472319.
