Dimensions External Cowl : 160mm x 190mm Internal vent : 160mm x 160mm Core Tube length : 127mm Dia x 350mm ( Core tube can be cut to accommodate wall thickness ) The Manthorpe 5" Core Drill Vent G900 is designed for use when ventilating a gas appliance, but can also be used for general through wall ventilation. The vent can easily be fitted in both refurbishment and new build situations with the use of a 5" (127mm) diameter core drill. The kit includes a cowl vent for exterior use, a louvre grille for inside, a 350mm length of pipe duct and an optional anti-draught baffle. This baffle reduces the airflow and also the feel of a draught through the vent. The external cowl minimises uncomfortable draughts, reduces noise and light from outside the property and acts as a barrier against wind driven rain whilst providing a free area of 100cm² and is available in both brown and terracotta. The Louvre fits on the internal wall and, similarly to the cowl, reduces draughts, noise and light penetration, while providing a free area of 100cm², it is only available in white. For situations where the total wall thickness exceeds 350mm, a 1,000mm pipe duct can be purchased separately. ## Features - Air Ventilator Core Drill with Terracotta Hooded Cowl - Air Ventilator Core Drill with Terracotta Hooded Cowl - Meets requirements for British Gas - Ventilation for heating and gas appliances. - Simply core drill through wall and place vents internally and externally. - 10,000mm² of airflow ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B00TKIC3MQ | | Batteries Included | No | | Batteries Required | No | | Best Sellers Rank | 390,976 in DIY & Tools (See Top 100 in DIY & Tools) 1,905 in Registers, Grilles & Vents | | Colour | Terracotta | | Customer Reviews | 4.2 4.2 out of 5 stars (18) 4.2 out of 5 stars | | Date First Available | 13 Feb. 2015 | | Guaranteed Software Updates Until | unknown | | Item Package Quantity | 1 | | Manufacturer | Manthorpe | | Manufacturer Reference | hsmart-670 | | Part Number | hsmart-670 | ## Images ![5" Core Vent Cavity Ventilator Anti Draught Terracotta Cowl for Gas Appliances - Image 1](https://m.media-amazon.com/images/I/51QfrMNZdoL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy retrofit for existing vent *by on Reviewed in the United Kingdom 17 November 2021* I bought this as a retrofit replacement for a very draughty 5" vent. I removed the old exterior and interior grills, and was relieved to find that the replacements (and the baffle) fitted neatly into the existing tube, so I didn't have to remove the old tube and fit the new one.If you need to drill a 5" hole, then that's probably something left to an expert, but if you're retrofitting then you might get lucky, like me.With the baffle and vents, the improvement is dramatic. If this is for a gas appliance then the effective area (with baffle fitted) is 75 square cms. This is 50% in excess of the requirement for my gas central heating, but you must check to make sure that the vent will let in enough air for your system. Call a gas engineer in you're in any doubt. ### ⭐⭐ Plastic tube for the duct does not fit a 5’’ core drill!!! *by on Reviewed in the United Kingdom 7 January 2023* Core drill needs to be 6mm larger than 5’’ !!!!! ### ⭐⭐⭐⭐⭐ Five Stars *by on Reviewed in the United Kingdom 17 December 2017* It will adequately do what far more expensive ones do. --- ## 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.fr/products/69465384-5-core-vent-cavity-ventilator-anti-draught-terracotta-cowl-gas](https://www.desertcart.fr/products/69465384-5-core-vent-cavity-ventilator-anti-draught-terracotta-cowl-gas) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-10-28*
