Product Introduction

The circular damper, also known as a circular baffle door, circular shut-off door, or circular regulating door, is primarily used in power plant air ducts and flues for intercepting or regulating the flow of media. It can also be applied in air ducts and flues in other industries. The circular damper enables complete flow or shut-off of the medium in a specific pipeline within the system or allows the medium flow to be adjusted based on control requirements.
