The SolaDirect 100mm Through-Wall Ventilation Kit is designed for homeowners and contractors seeking a reliable, all-in-one solution to improve airflow in bathrooms, kitchens, and utility rooms. This kit provides a complete route for stale air to exit the building, featuring a durable 500mm rigid PVC duct, an adjustable interior grille, and a protective exterior cover with a backdraft damper. While it offers excellent versatility for various wall thicknesses, users should note that the duct requires manual cutting to fit specific structural depths during installation.

Yes, you can purchase standard 100mm PVC ducting connectors and additional piping if a longer run is required.
This kit is suitable for passive ventilation. If you are using a powered extractor fan, ensure the fan motor is rated for a 100mm duct diameter.
You will need a drill with a 100mm core bit, a measuring tape, a level, a saw for the PVC duct, and silicone sealant.
Yes, SolaDirect offers variants in other finishes, such as black or brown, under different model numbers.
The interior grille features a rotating or shutter mechanism that you can manually adjust to open or close the airflow path.
Ensure the external backdraft damper is free of obstructions and sits flush against the wall cover.
Check the internal insect screen for accumulated dust or lint and clean it using a soft brush or vacuum.
Verify that all mounting screws are tightened and the grille is properly seated against the wall surface.
Installation requires a 100mm core drill or a hole saw capable of creating a clean opening through your wall. Ensure you measure your wall thickness accurately before cutting the 500mm PVC duct to size. Once the duct is placed through the wall, seal the exterior and interior gaps with suitable silicone or mortar to prevent moisture ingress. Maintenance is straightforward: the indoor grille should be periodically removed and cleaned of dust, and the insect screen should be checked for debris to ensure airflow is not restricted. If the backdraft damper becomes stuck, a quick cleaning of the hinge mechanism with a damp cloth is usually sufficient to restore smooth operation.
