CleanSeal EC Fan filter controller is a specialized electronic device or system that manages the operation of fan filter units in cleanrooms and controlled environments. It regulates fan speed (for EC Motors) to maintain consistent airflow, pressure, or air changes per hour. It also provides motor status, runtime, provides local control (touchscreen), and enables remote integration with building automation systems via website interface (Modbus, 0–10 V, etc.) for centralized monitoring, alarms, energy optimization, and fault reporting across large installations.
