764m3/H High Pressure Blower Fan Dc Small Centrifugal Fan 12v B Insulation Class
EC Fan Introduction
EC(Electronically Commutation) motors, as built-in DC inverter driver three phase AC external rotor permanent magnet synchronous motors, its efficiency and low noise is considered to be ultimate fan energy technologies.
Core Technology Of EC Fan Controller
1. Sensorless vector control software
2. High-performance power electronic circuits
3. Security and reliability design(Standards, Certification)
4. Embedded design

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.
We are independent of factory. This make us standing in the
position of client instead of factories. It will solve your problem
of communication with factory.
We absorb new knowledge and business way Internationally. This make
us be able to give more marketing suggestion and new cooperation
ways.

space.
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.
