Brushless DC fan saves the excitation of collector ring and brush,
greatly simplifies the structure; not only improved the technology
of motor but also greatly enhance mechanical reliability of motor
operation and increase the service life
Brushless dc fan use a permanent magnet excitation, eliminate the
loss of induction motor excitation currents; realizing the small
loss an high efficiency characteristics
External rotor axial fans series product:
1. Compact configuration, convenient installation and credible
running
2. Pressure high, airflow stable
3. Little noise, energy saving and highly active
4. Several speed rang, adapt to both frequency conversion and
voltage transformation, speed changing active
5. AC single phase 230+/-10% vor three phase 400+/-10%V are
alternative for voltage and 50hz or 60hz for frequency
6. Extensive application: can be widely used in refrigeration and
ventilation fields such as duct fans and roofing fans.
7. The safety grade of this series if IP54 and the insulation
classes are available among B,F and H.
8. The products have got the CCC certificate in China and CE
approval in Europe.
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.
FAQ
Can we buy a sample for testing?
Sure, you are welcomed to buy a sample before mass order.
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
