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.
