The openings look quite narrow.** A: Iv' e used these on a number of bathrooms, and are far better than those ugly louvered things. Airflow will be fine with any 4" fan. The centre is adjustable, so you can make the opening bigger. **Q: what size hole saw do i need for the ceiling opening?** A: About 102mm or 103mm for a close fit. There are circular saw blades of this size on the market. **Q: can this be soffit fixed?** A: Unable to answer from personnel experience as used on a ceiling application, but depends upon depth of soffit material but worked fine on 12mm lasterboard. Is thinner material it may require appropriate packing. **Q: Can I use this as a wall vent** A: Yes internally, as long as there is a large enough size hole to accommodate the vent and any associated ducting. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good value *by B***S on 2 January 2026* Good value ### ⭐⭐⭐⭐⭐ Quality product , easy to fit *by M***R on 30 June 2024* A good quality item , easy to fit and looks good . ### ⭐⭐⭐⭐ Like it... *by A***R on 28 February 2024* Easy to install, looks good. ## Frequently Bought Together - Kair Plastic Round Ceiling Vent 125mm - 5 inch Diffuser/Extract Valve with Retaining Ring - Kair PVC Flexible Hose 125mm - 5 inch Universal Tumble Drier, Cooker Hood, Extractor Fan, Air Conditioner Hose - 3 Metre Length - Kair MultiFan In Line Fan 125mm with Timer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nz/products/61616206-kair-plastic-round-ceiling-vent-125mm-5-inch-diffuser-extract](https://www.desertcart.nz/products/61616206-kair-plastic-round-ceiling-vent-125mm-5-inch-diffuser-extract) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-05-04*
