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
| Type | Nomual voltage (VAC) | Frequency (HZ) | Speed (rpm) | Power imput (w) | Curreng draw (A) | Sound pressurelevel (dB) | Perm.amb.temp |

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.
