Pa66 220mm EC Centrifugal Fans With Filtering Ffu Air Source Heat
Pumps
EC Motor – Principle
With an EC motor the electronic circuitry stands in lieu of the
traditional mechanical commutation meaning the right amount is
being supplied in the right direction at exactly the right time
providing precise motor control

AC vs. EC
The available range of AC input EC fans is expanding all of the
time. There are axial and centrifugal fans, forward curved and
backward curved, single inlet and double inlet, single phase and
three phase and they are often directly interchangeable with their
AC equivalents. EC offers the OEM more than just energy-efficiency.
It is an opportunity to bring new technology and functionality to
their products. With ever-increasing demand for energy efficient
systems, when it comes to fan based products, there’s no reason for
manufacturers not to have any in their portfolio.
Variable speed control of EC fan can be realized / achievedvia
0-10V speed adjustment and/or external circuit impulse modulation
Constant torque ,constant speed and constant airflow of EC fan can
be fulfilled via 180,sine SVPWM(Space Vector PWM)to meet customer
needs
Intelligent EC fan can support users to realize centralized
operation control by 485 bus and monitor as many as 255 fans
FAQ
1.Can we buy a sample for testing?
Sure, you are welcomed to buy a sample before mass order.
2. 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.
Why choose us?
1. We belongs to the factory, so price we can give is based on
factory cost, not trading cost.
2. We are sole International sales of the factory, we can help to
control and protect the market of clients.
3. We integrates different kinds of products for air management.
4. 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.
5. We absorb new knowledge and business way Internationally. This
make us be able to give more marketing suggestion and new
