バックドラフトダンパー (ABS、白、3/5/6/8 インチ)

Keep airflow moving in the right direction with confidence. The ABS Backdraft Damper is designed to ensure steady, one‑way ventilation — stopping unwanted reverse air, odors, and dust from flowing back into your system.

Made from high‑quality white ABS plastic, it’s lightweight, corrosion‑resistant, and impact‑resistant, making it a dependable solution for long‑term use in HVAC and ventilation systems.

Available in 3 inch, 5 inch, 6 inch, and 8 inch duct sizes, this damper fits seamlessly into a wide range of installations. The internal flap automatically shuts when airflow stops, preventing backflow and maintaining cleaner, healthier air indoors.

Whether used in residential, commercial, or light industrial ventilation setups, the CHIC ABS Backdraft Damper provides quiet, efficient, and reliable airflow control — a small part that makes a big difference in overall system performance.
