Back Draft Shutter 100 mm Metal – One-way airflow, zero back draft

Back drafts cause cold air, unwanted odours and moisture to enter a room through the ventilation duct whenever the extractor fan is off. The Back Draft Shutter 100 mm Metal solves this with a simple mechanical flap that opens under airflow and closes automatically when the fan stops. It fits a wide range of applications: bathroom ventilation, kitchen extraction, toilet fans, garage air systems and indoor grow rooms. See all available sizes in our back draft shutter category.

Where it makes a difference

Back draft shutters are particularly valuable in bathrooms and kitchens, where odours and humidity can travel back through shared ducting in apartment buildings or terraced houses. They're equally useful in grow rooms to prevent smell leakage when the extractor is not running.

Metal build for long-term reliability

The metal construction withstands moisture and temperature changes better than plastic alternatives, making it a sound long-term investment. This coupler connects two Ø100 mm air tubes and slots into any standard ventilation setup. Combine with a soundproof casing for a quieter system overall. Fast delivery across Belgium.

Does the Back Draft Shutter 100 mm work for bathroom or kitchen ventilation?

Yes — bathroom and kitchen ventilation are among the most common uses for this shutter. It prevents cold air, cooking smells and humidity from re-entering the room when the fan is off. Make sure your duct diameter is 100 mm before ordering.
