Designed specifically for use with 100mm extractor fans, it offers a fuss-free solution that completes wall installations with a professional appearance. The gravity-operated louvres respond automatically to airflow, opening when the fan is in operation to allow moisture-laden or stale air to escape, and closing securely once the fan ceases.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cspan\u003eEngineered for practical functionality, this shutter serves as an essential component in maintaining indoor air quality while protecting the property from external elements. Its compatibility with both rigid and flexible 100mm round ducting makes it suitable for a wide range of ventilation applications, including bathrooms, kitchens, utility rooms, and commercial spaces. Beyond its primary ventilation role, the self-closing louvres provide effective barriers against backdraughts, rain penetration, and unwanted pests, ensuring that when the system is not active, the wall opening remains sealed against the outside environment.\u003c\/span\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003e\u003cspan\u003eKey
