The Universal AC External Vent Kit – 100‑150 mm Wall Duct Set (Brown) is a complete, ready‑to‑install solution for any split‑system air conditioner that uses a 4″, 5″ or 6″ vent hose. Designed for both DIY enthusiasts and professional installers, the kit keeps moisture out, stops drafts and gives a tidy finish to your wall vent.
Key benefits
– Condensation control: The non‑return cowl flap blocks outside air, reducing the risk of water damage inside the wall cavity.
