Manual‑electric louver air damper

Adopting louver‑blade structure, the manual‑electric louver air damper is equipped with both manual and electric driving systems. It supports both on‑site local operation and remote electric control adjustment. Mainly used for rectangular air ducts, it realizes precise regulation of air volume & air pressure as well as pipeline on‑off control. Blades and frames are made of wear‑resistant steel plates with mature welding and machining processes. Multi‑blades work synchronously with excellent sealing performance. It features high‑temperature resistance and dust tolerance for complex sites such as industrial ventilation and flue‑gas treatment.

Deep non‑standard customization is supported. Customization is available based on customer duct size, pressure‑temperature parameters and driving configuration requirements. All finished products pass multiple strict inspections before delivery. We provide product warranty together with comprehensive technical consultation and after‑sales support.
