Save Energy on Air Compressors

Variable speed control for all types of industrial equipment is now readily available on the market and VFD is
adopted in air compressor application to control the speed (RPM) of the unit, which in turn saves energy
compared to a fixed speed equivalent. The VFD article provides additional information on electronic speed
controls used with various types of AC motors.

The benefits of this technology included reducing power cost, reducing power surges (from starting AC
motors), and delivering a more constant pressure. The down side of this technology is the heavy expense
associated with the drive, and the sensitivity of these drives – specifically to heat and moisture.

Typically, a fifth of a factory's electricity bill is attributed to the production of compressed air. The majority
of modern factories are heavily involved in cutting costs, and energy awareness should be a key concern.
For example, 10–12% of all power generated in the China is dedicated to the production of compressed air,
and a portion of this power is wasted energy. Large electrical cost savings can be achieved by installing a
VFD onto air compressor. Because of this, many governments are pushing the industries to move towards
this technology in hopes of reducing wasted energy.

E6A, E6B of BEST TECHNOLOGY are special models based on E6 series, which is a new generation of
special air compressor high performance vector inverter.
 

Applications of E6A: 
    air compressor asynchronous motor,
    permanent magnetic synchronous motor open loop drive,
    factory default is asynchronous

Applications of E6B:
    air compressor asynchronous motor,
    permanent magnetic synchronous motor open loop drive,
    factory default is synchronous.

The only difference between E6A and E6B is factory default, which is to simplify user bugging.
