Universal Range Hood Backdraft Check Valve for 150–180mm Ducts

Keep cooking odors and exhaust from drifting back into your kitchen with a range hood check valve designed for one-way airflow. Its butterfly-style damper opens when the hood is running, then closes by gravity when airflow stops to help block odor, dust, and exhaust backflow. The heat- and oil-resistant PP housing suits demanding kitchen ventilation areas, while the double-ended connection supports common duct sizes. This backdraft damper for range hood is a practical upgrade for improving exhaust control. Joom

Why Choose Our Universal Range Hood Backdraft Check Valve?

Unlike a plain duct connector, this kitchen exhaust check valve actively helps stop air and odor from flowing backward after the fan shuts off. Its double-ended adapter design also makes it easier to connect compatible flexible or rigid ducting without replacing the entire exhaust system. Fruugo

Perfect For

Range hoods, kitchen exhaust fans, wall vents, flue outlets, ventilation ducts, apartments, restaurants, and home kitchen upgrades.

How It Works

Airflow pushes the anti odor duct valve open during exhaust. When the fan stops, gravity closes the butterfly flap to help seal the duct and reduce backdraft. Lazada Philippines
