Adjusts the fan speed (airflow capacity) by changing the current frequency.
Collects all signal from different sensors.
Monitors the pressure in the ventilation system and sends corresponding signals to frequency converter to adjust the RPM of the central fan.
For extraction funnels
EC energy control device starts/stops the central fan by receiving signals from various types of sensors.
