En mi caso el tubo era un par de milímetros mayor y lo he colocado con un poco de cinta para fijar e impedir paso de aire. Lo he combinado con extractores que ya tenía y también en ventilación pasiva con el tubo en horizontal, va perfecto. ## Frequently Bought Together - Kair Connector with Backdraught Shutter 150mm - 6 inch Non-Return Damper Flap to Connect Duct Pipe or Flexible Ducting Hose - Kair 90 Degree Elbow Bend 150mm - 6 inch Round Plastic Ducting Joint to Connect Round Duct Pipe or Flexible Hose - Kair Plastic Ducting Pipe 150mm - 6 inch / 350mm Short Length -Rigid Straight Duct Channel --- ## 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.es/products/412374886-kair-150mm-6-inch-backdraught-shutter-ducting-connector](https://www.desertcart.es/products/412374886-kair-150mm-6-inch-backdraught-shutter-ducting-connector) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-05-24*
