• Widely used in ventilation system in the clean room;
• The FFU computer can independently monitor the FFU for 24 hours;
• Computer central monitoring system;
• Control the open and close of hundreds of FFU through the computer;
FFU, as a purification device, has been widely used in ventilation system in clean room. The monitoring system connects with hundreds and thousands of FFU by FFU computer host to control and close of fan, malfunction altering and recording data. When the computer of FFU monitoring system is closed, the FFU computer can independently monitor the FFU for 24 hours.
FFU group control system is applied to clean room with a large mount of FFU.
