Description
Ensure a professional finish for your ventilation system with the Manrose DHRIWKBBS. This internal wall kit is the perfect solution for venting extractor fans through external walls. It provides a neat, weatherproof exit point for your 100mm ducting.
The standout feature of this kit is the integrated backdraught shutter. When your extractor fan turns off, the gravity shutters close automatically. Consequently, this stops annoying rattles and prevents cold wind from blowing back into your bathroom or kitchen.
Installation is straightforward and efficient. The kit is designed to fit standard 100mm (4″) circular ducting. Additionally, the brown finish is ideal for matching traditional brickwork or dark wood exteriors. Specifically, the UV-stabilized plastic resists fading and cracking over time. By choosing the Manrose DHRIWKBBS, you guarantee a more energy-efficient home by reducing unwanted heat loss.
