Quick-opening dampers play an important role in industry, especially in ventilation systems. The main feature of a quick-opening damper is its ability to open or close quickly, thus enabling rapid control of airflow in the duct. It is usually made of robust and durable materials to withstand the pressure and impact of airflow in the duct. Its structural design focuses on ease of operation and speed of response, and it is generally equipped with highly efficient actuators, such as electric or pneumatic actuators, capable of completing the opening or closing action in a short period of time.
