Product Description

50 / 60HZ EC Centrifugal Fans 225mm And Blowers With Air Purification 3300RPM



Constant pressure : Used in conjunction with a pressure sensor, the fan maintains the same pressure at varying airflow (ideal for ducted applications). Operates with forward curved centrifugal fans without pressure sensor and with backward curved motorised impellers with pressure sensor (Available on Ecofit fans).

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


Warranty: 1 year warranty for all products.


Private Labelling: All of axial fans are able to be Private labeled.
