The "PEC-X" is a room pressure controller equipped with a microcontroller, significantly enhancing operability, functionality, and reliability. It is a system that integrates a pressure sensor, controller, and a motor that opens and closes the air conditioning damper, controlling room pressure by varying the exhaust volume while maintaining a constant air flow from the air conditioning. Its greatest strength is the ability to achieve the set room pressure more accurately and in a shorter time than the "VAV (Variable Air Volume)" system, which has been used for inter-room differential pressure. Additionally, the settings and current values are easily checked via a digital display on an LED, and the setting or modification of control parameters can be easily operated with push buttons. It contributes to strengthening cross-contamination and infectious disease measures in the field of biological clean rooms, as well as to the competition for high precision and high quality in the field of industrial clean rooms. 【Features】 ■ Compact all-in-one type ■ Improved control and high precision ■ Enhanced operability ■ Increased convenience ■ Improved communication functions ■ Easy on-site installation *For more details, please refer to the PDF document or feel free to contact us.

Pressure Control Damper (PCD) The 'PEC-X2' is a compact room pressure controller that excels in controlling differential pressure between rooms, such as in clean rooms and waste treatment facilities. It maintains the performance of our conventional models while being miniaturized, enhancing design flexibility. With the ability to set alarms within a range of ±200Pa, there is no need for a pressure switch for room pressure monitoring. Additionally, it features a timer function that allows you to set a delay for the output, preventing alarms from reacting to instantaneous abnormal signals, such as during door openings and closings. 【Features】 ■ Now compatible with AC24V power supply ■ Utilizes MODBUS communication for easy communication with external devices ■ The control panel's footprint is reduced by half compared to conventional models, resulting in significant miniaturization ★ In addition to product materials, we are also offering a sample of actual measurement data on room pressure control. You can view it immediately from the "PDF Download" section.

It measures the actual differential pressure between rooms and controls the damper with an internal controller and motor to maintain a constant differential pressure. No major construction is required! It allows for easy control, monitoring, and management of differential pressure.

Are you managing the airflow in the cleanroom? I believe that at the beginning of factory operations, the airflow direction was determined by adjusting the supply and exhaust air volumes. However, over time, it may not have been maintained due to filter clogging or changes in equipment. The differential pressure controller 'PEC-X2' maintains the airflow direction over the long term by controlling the differential pressure between rooms. Controlling the supply and exhaust air volumes with dampers means that when it can no longer be controlled, it is truly time for maintenance. By issuing an alarm at this timing, it can lead to longer filter life and reduced maintenance costs. We are also developing a 'Room Damper' that enables ductless differential pressure control, which is scheduled to be released soon. Please feel free to consult with us.

It is possible to maintain and manage the differential pressure between rooms independently. ◆ The damper is equipped with a motor, pressure sensor, controller, and display. ◆ Active control stabilizes the differential pressure between rooms. ◆ The control range is wide, and it can accommodate low air volumes. ◆ It has the same opening as conventional products, allowing for easy replacement. ◆ It is possible to switch between negative and positive pressure without changing the installation orientation. ◆ Differential pressure settings can be made in increments of 1 Pa.

The "PGC1" is a centralized room pressure controller that can manage multiple Okaya Seiritsu Kogyo room pressure control devices together. It allows for remote management of control parameter changes for room pressure control devices, acquisition of current room pressure values, and confirmation of alarm statuses. Previously, it was necessary to go up to the ceiling space, but now it can be monitored remotely from the machine room, eliminating the need to access the ceiling space and improving work efficiency. Additionally, it enables the miniaturization of control panels and reduces wiring and piping work. 【Advantages of Implementation】 ■ Improved work efficiency through remote monitoring ■ Miniaturization of control panels ■ Communication possible with just wiring *For more details, please download the PDF or feel free to contact us.
