Working Principle
The FFU draws air through the fan section and delivers it through a high-efficiency HEPA or ULPA filter. The integrated RS communication module enables each FFU to communicate with a central controller or Building Management System (BMS).
Multiple FFUs can be connected in a network using RS-485 communication, allowing centralized monitoring and control of:
- Fan speed
- Airflow performance
- Operating status
- Alarm conditions
- Filter maintenance requirements
- Energy consumption trends
- This intelligent control architecture improves cleanroom performance while reducing operational costs.
