The basic interface: 0-10V/PWM, RS485/Modbus, 4-20Ma


The basic parameters of field programmable: Maximum speed, minimum speed, maximum power,


Let’s assume a laminar flow workstation requiring 13200m³/h at 450Pa. This requires 4 off Ø315 backward curved fans.


Now let us assume that this workstation operates for 50 weeks of the year and for 8 hours per day at full speed. During non working hours to


maintain the work area, the fans are run at roughly half the airflow.

AC fan 2800hrs @ 4 x 1.41kW = 5.64kW 15,792 kWh
5600hrs @ 4 x 0.62kW = 2.48kW 13,888 kWh
Total A 29,680 kWh
EC fan 2800 hrs @ 4 x 1.04kW = 4.16kW 11,648 kWh
5600 hrs @ 4 x 0.27kW = 1.08kW 6,048 kWh
Total B 17,696 kWh
A minus B 11,984kWh saved with the EC fan


aster/Slave : This system is used when several fans are used together within a single application. The main fan (Master) is individually pressure


controlled. The other fans (slaves) are then speed controlled by the Master fan : Slave Fans are always at the speed of the master fan (Rosenberg Versions only).
