I need 120mm** A: Good day, There is no 120mm if you have a ventilation pipe of 125mm, then take a 125mm VKE **Q: Hi. Can this be used for a gas boiler flue. Many thanks** A: Hi Kirsten t , mmm this question should be directed to your boiler manufacturer. Boiler flues should not be obstructed in any way. If you want to provide a flue low pressure equalizing valve, using a corrosion proof material, such as stainless steel, it would have to be mounted in an adapter ‘box’ to provide for full deflection of the louvre plates, when the pressure in the flue is below atmospheric pressure. Mounting it inside the flue, would expose the mechanism to soot and or creosote ( depending on the fuel you are using ) In the exhaust gas flow is not good practice. I would strongly advise asking your boiler manufacturer this question. ‘Google’ their ‘official’ web site, ask for technical support . In my experience, I have found the ‘expert engineers ‘ will give you a definitive answer. It is very important not to interfere with the aspiration of the boiler , which has been carefully calculated, to provide efficient combustion and compliance with emission regulations . **Q: Can it be used for tumble dryers ?** A: Good morning, you can use the VKE 100 for your tumble dryer because it is made of stainless steel and will not rust. **Q: Hi, i bought 3 4inch air vents on 4th feb. going to buy another 4" & 5" & see that you have put the price up by £5! what is the reason for that?** A: Good day, At the beginning of the year, the suppliers raised surcharges, these must be apportioned. ## Frequently Bought Together - calimaero® VKE 4" Inch Dryer Vent Cover – Outdoor Stainless Steel Grille with Moving Flaps – Fits Only with Metal Ducts for HVAC & Dryer Systems - calimaero® 2 Pack Bird Stop Dryer Vent Grill Screen Guard Insert 8.8in x 8.8in Customizable 3inch to 8inch Stops Nesting in Bathroom Exhaust Vents - calimaero® HWG 4" Dryer Vent Cover Outdoor Walls - Cowled External Extractor Fan Vent Dryer Cover - Robust and Weatherproof Stainless Steel Outdoor Dryer Vent Cover - Fits Only with Metal Pipes --- ## 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.ma/products/116445940-vke-air-vent-covers-exterior-100mm-gravity-grille-backdraft](https://www.desertcart.ma/products/116445940-vke-air-vent-covers-exterior-100mm-gravity-grille-backdraft) --- *Product available on Desertcart Morocco* *Store origin: MA* *Last updated: 2026-08-25*
