Resemble Ebm-past PA66 EC Centrifugal Fans With Backward Curved Blades

Currently, both at home and abroad, the EC axial fan has been widely used in various fields, especially ventilation, large air conditioning and refrigeration. The compact structure and continuous controllability of EC centrifugal fan has been into full play to air handing units, computer modules, communication systems ,clean room systems, roof fans, home machine automotive and rail technology

Protection: over voltage, over temperature, over current, phase loss detection, communication failures.

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

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

Constant air pressure controlling function

Embedded design

Electro magnetic compatibility (EMC)

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

if the fans doesn't work well, what shall I do ?

If happens within one year, we will take in charge of the maintenance, or send you a new machine freely.
If after one year, we will supply you the right parts to replace at low price.

Can we buy a sample for testing?

Sure, you are welcomed to buy a sample before mass order.
