Powerful 2 Stage Air Compressor / Stainless Steel Air Compressor Oil Type



1. High quality of airend


  • The rotor adopts advanced high-efficiency molded lines, which ensures stability and high-efficiency;
  • It adopts two-stage independent compression, same pressure ratio, low speed design, thus enhancing more than 15% of air volume under the same power;
  • Guarantee of low compression ratio at every state, smaller host engine leakage, higher volume efficiency;
  • It adopts oil mist spray cooling at stage intervals, so as to make the entire compression process close to isothermal compression, thus improving the compression adiabatic efficiency;
  • The two segment rotors are directly driven by bevel wheel, so that each rotor obtain the best line speed, and the compression transfer efficiency is the highest;
  • The rotor and bearing have small load, the constant operation of host engine ensures long life;

2. Highly efficiency and energysaving screw airend


The air end is connected with big rotator and is designed with low rotat-ing speed, and it contains two independent compression units. It is featured by high efficiency, low noise, low vibration, high reliability, low compression ratio in each stage, smaller leakage and high volume efficiency. Under the same power, two heads bear load while bearings bear small load with longer service life.


3. Highly efficient and energy-saving permanent magnetic motor


The airend is highly efficient and energy-saving permanent magnetic motor with protection level of IP55 which is elaborately selected according to requirement of application of air compressor, it reaches national grade-1 energy efficiency standard, both torque and load can meet special design standard so as to achieve optimization of motor efficiency and power factors under loading conditions. This optimized coefficient has about 5%-8% advantages when compared with efficiency of other motors.


4. Highly efficient and energy-saving filter system


Highly efficient oil-gas separator with special simplified design, aggregated separator core and oil return device, its service life is 6,000h. Oil filter is of low-pressure design with service life reaching as long as 4,OOOh, and high filtering precision protects bearing and screw rotator.

Air filter doesn’ t need to change air flow direction when doing filtering, instead, it directly runs through filtering medium, this reducing pressure loss, it is more energy-saving than traditional air filter with large filtering area, higher compactness and longer service life.


5. Highly efficient cooling system


It adopts highly efficient fin-type cooler with large heat exchange area, surplus of heat exchange being 30% and more optimal cooling effect, and it can normally operate under environmental temperature 45°C.


6. Energy-saving air inlet control system


New-type integrated inlet valve of professional design with large range of air inlet adjustment . It has valve regulation with small pressure loss, stable movement and long service life. Key part of inlet valve—magnetic valve uses internationally famous brand, which guarantees absolute operating safety and



Permanent magnet frequency characteristics


1. 24-hour warning sending of the system


The warning systems of maintenance and breakdown are triggered as soon as maintenances are needed or breakdowns happen.then the equipment management members and the mainrenance members of the distributors will be informed at the soonest time through the way of message or email,through which,both the secondary loss and the major breakdowns of the machinery can be avoided.


2. The easy and quick operation method

The operation mode of ueasy managemenf with a touch screen makes it easy and quick to revise parameters.Meanwhile.in order to turn the intelligent network control to be reality,intelligent power-on and power-off or pressure setting within certain periods can be set.


3. A real time check on the operational parameters and breakdown warnings of the machines can be achieved through the remote monitoring system.


4. The breakdowns under moving cirumstances can be dealt with timely and quickly.


5. Based on being human-oriented and taking services as the top priority,the APP terminal systems can provide convenient and efficient control and use conditions and then provide safe,reliable and considerate services to pepole through firstly performing a good management at anywhere and anytime.


Energy saving Mute environmental



1. The big data information-based management system


Master all kinds of information,use information,have a trial use of the information as well as find out the problems and breakdowns etc. at anywhere and anytime,and them provide the most valuable.timely and improrant information and finally improve various effciencies.


2. Save as much as 50% electricity

When the demand for air changes drainatically, the average energy saving rate is over 50%. There is no waster of idling and unloading, no peak start current, so that reduce the energy consumption of air compressor.


protection Subversion tradition Lead the future

  • The extremely efficient and synchronic motors
  • Its efficient turnning frequency with a broad range makes gaining much more energy-saving operation space possible.
  • With the same power, in contrast with the air displacement produced by the single-stage compressors,an extra 15% of air displacement will be produced by the two-stage compressors
