Product Parameters



Product Display


1) 100% OIL-FREE :

    TUV Class 0 Oil-free Certificate

    Clean air:purified by water,without dust



2) At Least 30% Energy-saving :

     Single screw air compressor theoretically doesn’t have any clearance volume

    The water used as a lubricating medium also seals gap inside the compression chamber,and enables high efficient operation at low speeds(about 3000r/min)

    Using water as a cooling method keep compressor Ideal isothermal compressio

    Variable frequency inverter(Permanent magnetism variable frequency)


3) Environment protection :

    No discharge of three wastes; Low vibration and less noise


4) Reliability :

    Simple and balance structure and the temperature of the unit is less than 50℃,so maintenance period more than 50000 hours

    Lowest cost and maintenance (Only air filter and water filter < $500)


5) Low noise

     Superior dynamic balanced system can effectively control the vibration source

     The motor and screw are directly connected without any rotation gear to cause gear noise

    Sound absorbing materials are also used in the equipment shell to reduce noise







Detailed Images



High-quality and efficiency motor especially for

screw air compressor.

Protection level : IP55

Insulation class : F

Bearing : SKF


Medical stainless steel

would ensure

the gas to be clean and safe.


To derive magnesium ions and calcium ions from water to effectively prevent the host internal circulating water scale and extend the service life of the host.



Each stage can achieves

a low temperature of discharge airflow:

only 5-15℃ higher than the ambient temperature.









30 years' experiences made

first-class quality of the host, which are on the top level

in this field;




 Male rotor use copper alloy

 Star wheel use polymers:

 Good abrasion resistance

 Low noise

 Good heat dissipation

 Long service lif



Saving 20% energy


PLC integrated control;

it can effectively control the use of energy and ensure the long and efficient operation of the compressor



The advanced controlling and monitoring system can display all operation parameters clearly and prevent accidents by appearing failure alarm on computer and sending messages to managers.


1.Only Air filter and Water filter: <$500/year.

Based on environmental condition,replacement of

the air filter element for each 500-2000 hours; 

the water filter element for each 2000-4000 hours.



Adopt imported famous brand component to insure the equipment running stable.
