Allvent Non Return Damper 100MM

The Allvent ALVBD10 ALV339 Non Return Damper is a 100mm in-line ducting accessory designed to help prevent backdraft in circular ventilation systems. Its air-stream operated backdraft shutter makes it a practical choice for bathrooms, laundries, toilets, kitchens, utility areas, roof spaces and light commercial ducted exhaust installations where airflow needs to discharge in one direction. Designed for installation in-line with circular ducting, it helps improve ventilation performance by reducing unwanted air return through the duct run.
