Simply realize accumulated know-how.
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).

Applications/Examples of results
The orifice or Pitot tube detects the air flow and provides feedback. The damper opening is calculated using PID computation, and the damper opening is adjusted to achieve the set air flow. By connecting the fume hood monitor and sash sensor, it is possible to respond to the fume hood. By performing supply and exhaust interlocking control, the room pressure balance during local exhaust operation is maintained. 1. Configuration The high-speed VAV/CAV consists of an integrated structure of damper, actuator, differential pressure sensor, and controller. 2. Fume Hood Monitor - Displays the suction surface wind speed of the fume hood - Notifies various alarms audibly - Supports emergency exhaust switches, etc. 3. Sash Sensor By connecting to the high-speed VAV, it detects the sash opening and calculates the opening area of the fume hood. It controls the face wind speed to 0.25 to 0.5 m/sec at any sash opening.
