It is ideal for applications that require rapid control of airflow, such as local exhaust and emergency exhaust in medical facilities, production lines (semiconductors and pharmaceuticals), and laboratories, as well as room pressure control due to airflow differences. With the fastest full stroke in one second and high-speed control, a differential pressure type airflow sensor is adopted. By providing feedback on airflow, it achieves high-precision airflow control. It also supports fume hoods and contributes to energy savings with low pressure loss. *1 Capable of high-speed response (fastest 1 second) *2 Achieves low pressure loss (effective static pressure: approximately 20-150 Pa; energy-saving compatible) *3 High precision: Unlike mechanical types, it allows for fine adjustments in addition to airflow changes. The installation direction is also flexible (horizontal duct, vertical duct).

"Energy saving" and "high quality" have become important keywords in recent times. The same applies to air conditioning dampers, where similar requirements are expected in the environments where they are used. In particular, there is a need to prevent cross-contamination, maintain cleanliness, and avoid exposure to hazardous atmospheres in environments such as medical facilities, production lines (semiconductors and pharmaceuticals), and laboratories. Control technology is necessary to prevent these issues while also achieving energy savings, starting with room pressure control dampers. These dampers directly feedback room pressure and control exhaust (or supply) dampers to achieve the set room pressure. - Miniaturization and cost reduction: Achieved through dedicated design and miniaturization for lower costs. - Improved operability: Standard features include digital displays and operation switches, enhancing usability. - Enhanced functionality: Standard implementation of room pressure and damper opening output, various contact input/output, and communication functions (Modbus communication). - Flexible response: Flexible adaptation to the site through various parameter settings, with parameters also adjustable via switches.
