Permanent-magnet brushless DC motor within the rotor
The stator is driven by electronic switches (which replace the Carbon brushes), controlled by a microcontroller.
Electronic system (hall effect sensor or software is used to recognize the rotor position)
AC operated (230Volts Single phase or 380/480Volts 3phase, 50/60Hz)
Why choose us?
We belongs to the factory, so price we can give is based on factory cost, not trading cost.

T/T, L/C, other kind of payment please contact with us
piece sample fan. We believe our fan quality must satisfy customer.
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.
What about delivery date?
Product can be sent to you within a week if there is stock after receiving deposit or 100% payment from customer. If there is no stock, the delivery date will be 15 to 30 days.
