Circular Sealed Damper
Circular Sealed Damper is designed to be used in circular ducted systems where complete sealing in the duct is required. This damper, which has Class 3 sealing class according to DIN EN 1751 standard, is resistant to a maximum pressure value of 1500 Pa. It shows effective performance between 10 - 50°C as working conditions. Damper blade adjustment can be done with manual lever or damper motor according to need and preference, thanks to this flexibility, it easily adapts to different system needs. With these features, the Circular Sealed Damper is an ideal option for applications requiring high sealing in air ducts.
