Main feature

Frequency-controlled function can be activated according to various needs of clients. We may provide all kinds of frequency controlled screw air compressor, the power from 5.5 KW to 280 KW, the air delivery from 0.6m3/min to 45 m3/min, the pressure from 0.5Mpa to 1.3Mpa , and with water cooling, air cooling, belt drive or coupling.

l  Well-known air end

l  Auto air inlet valve and unload-start system

l  Micro-computer control panel

l  Advanced cooling system

l  Humanized design easy for maintenance , reliable performance

The main feature of the frequency conversion screw compressor.

l  Adopt famous brand frequency-changing module in the world, adopt special motor with especial strengthen lifting characteristic, adopt a set of PID parameter especially fitting for the screw compressor, the controlling software has been tested by hundreds of compressors in the work, it's easy to set parameter and with good human-machine interface. It can be devised specially in the cooling of the frequency-changing machine to adapt to hot and humid climate. In order to help user to set up the best working pressure by oneself, the filtrating area of the oil-gas separating filter element has been enlarged.

l  Every type of Fortune brand screw compressor can have the function of frequency-changing as the requirement of the user. Its power is from 5.5KW to 280KW, air capacity is from 0.6m3/min to 45 m3/min, the work pressure is from 0.5MPa to 1.3MPa, there are water-cooling, air-cooling, belt driving, direct driving etc many configurations.

The microcomputer control panel

l  Humanization human-machine interface display controller.

l  Operate the machine easily and simply.

l  Be clear at a glance of the working status.

l  When the abnormal thing happens, it hints to be maintained.

l  When the temperature of the exhausted air is too high, or the compressor is overload, lacks phase etc, the machine will stop automatically or can't be started.

Special new motor with low consume and high efficiency

l  Big starting torque.

l  Insulation grade is F, Protection grade is IP54.

l  SKF axletree, low noise, long life.

l  Equipped with greaser, lubricates during working.

Cooling system

l  Big cooler, big diameter fan, adopts for more conditions.



Famous brand mainframe.

l  Equipped with famous screw compressor mainframe.

l  Special rotor tooth provides excellent performance for the all types of air ends.

l  Solid axial direction and radial axle tree ensures the long life of the machine.

l  three-ply hub envelop solves the problem about leakage in the critical districts.

l  The wearable harden shaft liner has been grinded critically, is easy to be maintained.

l  Every products has the top performance and efficiency in the world, uses the smaller motor power to produce bigger air capacity.

Automatic inlet valve and starting uninstall device:

l  proportional valve feeds back the 100%  pressure signal to servo cylinder and inlet valve.

l  Inlet valve adjusts the air capacity from 0% to 100% without grade, make the need air capacity to be same with the provided air capacity, and saves the energy to the most.

l  The smallest pressure valve assure the spraying pressure to     lubricate the machine, and can stop the valve athwart.

It's devised to be maintained easily and wholly.

l  The spacious servicing door makes the maintenance of the compressor to be very convenient.
