High efficient and reliable direct drive system 

The rator and motor direct draive through the flexible coupling, no transmission loss of energy consumption,higher transmission efficiency, higher reliability, bigger gas production, and more energy-efficient(22kw-250kw type);
 Rotor, sliding gears and motor through the EPT connect, the coupling transmission is more efficiency than the belt tansmission, also get more compressed air for the same energy consumption( 280kw-400kw type);
Automatic absorption of peak torque, avoid wallop. Reduce wearing parts, increase reliability,
and reduce maintenance costs.

Rotors are asymmetric in profile, backed up by ball bearings and roller bearings. Operates at a low speed, thereby low in abrasion and maintenance expenses, air end is long service life. Helical gears can produce axial force to kill some acting force, which reduces the load of the bearing of air end.

Control panel:
Intelligent microcomputer-based control EPT can monitor and control in all aspects the complete machine following your instructions, remote control realizes unattended operation, and the user-friendly human-machine interface displays instructions and parameters in written form also, it can function to self diagnose faults, give warning and automatically regulate the capacity.

Oil filter:
Rotary filters are applied to completely remove the impurities in the lubricating oil, easy to replace and free of oil impregnate.

It is designed for low temperature difference to increase heat exchange area, and ideal to be applied to high-humidity operating environment.

Excellent quality of motors:
Compared to normal motors, PM motors have smaller dimensions and more excellent energy saving.It will exert incomparable energy saving effect than normal inductive motor.

The air end machine of compressor is of high efficiency and long life:
The quality of host machine of permanent magnet variable frequency compressor is excellent. The advanced molded lines ensure the minimum specific power.It is designed in the FEM strength analysis.to ensure the stability and reliable of each part,and to realize long term operation with no faults,low noise and long life.
