100mm Through-Wall Ventilation Kit with 500mm Duct and Backdraft Grille for Bathrooms, Kitchens, Toilets and Utility Rooms

Complete Three-Part Wall Kit - Includes a white 500mm rigid duct, white indoor grille with insect screen and white exterior gravity grille for creating a direct 100mm airflow route through a compatible wall.

For Domestic Ventilation Projects - Suitable for bathrooms, kitchens, toilets, cloakrooms, laundries and utility rooms where humid, stale or unwanted air needs to be directed outdoors.

Indoor Grille with Insect Screen - The 170 x 170mm room-side grille connects to 100mm round ducting and provides a neat internal finish while helping restrict insects from entering through the ventilation route.

Exterior Grille with Gravity Louvres - The 190 x 190mm outdoor grille uses one-way moving louvres that open with outward airflow and help reduce cold draughts and reverse airflow when the system is idle.

500mm Rigid PVC Duct - Measures 100mm internally and 103mm externally, and can be carefully shortened to suit the wall depth. The outdoor cover includes 4 screws and 4 wall plugs.
