Available in 75mm and 110mm diameter sizes, made from durable ABS plastic for the damper body and reinforced PVC for the check valve flap. This combination ensures lightweight yet sturdy performance in ventilation systems.
Integrated electric actuator operates on standard 220VAC power, enabling remote or automated control of damper position (open/close) for precise airflow management in HVAC, exhaust, or air supply systems.
Features a built-in PVC check valve flap that automatically prevents reverse airflow (backdraft), ensuring one-way ventilation and maintaining intended air direction in ducts or vents.
Allows manual or automated adjustment of damper opening to regulate air volume, making it suitable for balancing ventilation, controlling smoke extraction, or managing fresh air intake in commercial or industrial spaces.
Designed with standard flanges or connectors for easy installation in round ventilation ducts. Compatible with auxiliary solenoid valves for expanded automation integration in smart building or industrial ventilation controls.
