Product Description

Low Noise Rail Transportation Industrial Fan Blower Filtering Ffu 225mm


What is EC technology?


EC Technology stands for Electronically Commutated and combines AC and DC voltages, which is essentially a fan with a brushless DC motor, bringing the best of both technologies: the motor runs on a DC voltage, but with a normal AC supply. DC motors already have low power consumption but if used in an AC application, the power needed converting AC to DC, using a bulky, inefficient transformer. The EC motor incorporates voltage transformation within the motor. The non-rotating part of the motor (stator) is extended to make room for an electronic PCB board which includes power transformation AC to DC, as well as the controls.



Energy savings with EC fans 


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
