22KW 30Hp Oil Free High Efficiency Screw Air Compressor

22KW / 30Hp 3.6m³ / min Energy Saving Oil-Free Screw Air Compressor

Main uses and guarantees:


The relationship between the three power, work pressure and volume flow rate
When the power is unchanged, the volume flow rate and working pressure will change correspondingly when the rotational speed changes. For example, a 22KW air compressor is manufactured with a working pressure of 7bar, and the rotational speed is calculated according to the technical curve of the main engine of the air compressor. The exhaust volume is 3.8 m3/min. When the working pressure is 8bar, the rotational speed must be determined. It must be reduced (otherwise the drive motor will be overloaded), at this time, the exhaust volume is 3.6 m3/min; because the speed is reduced, the exhaust is reduced accordingly, and so on.

The selection of power is based on the condition that the working pressure and volume flow are satisfied, and the power supply capacity can meet the use power of the matched driving motor.
Therefore, the selection of air compressor steps is: first determine the working pressure, then determine the corresponding volume flow, and finally the power supply capacity.



Two-stage compression reduces the compression ratio per level reducing intemal leakage and increase the volumetric efficiency reduces the bearing load, improve the working life of the host.
Two stage compression instead of single-stage compression,nearly a 15%increase in displacement,can realize a 15%more energy saving effect.



The technical advantage water lubricating oil-free screw air compressors

1.With the fifth generation of oil-free screw airend technology. The compressor airend and system adopt stainless alloy, thus the technological transcendence from the copper airend to the stainless steel airend is realized.

2.Integrated design is adopted for the whole machine. There are no complex pipelines and lines, and the fault points are less and more stable.

3.Less maintenance consumables (air filter, water filter), easy maintenance, no professional staff is required to operate it, and less maintenance costs.

4.There is absolutely no oil in compressor system, without any oil pollution risk, it gives guarantee of no oil in generated compressed air.

5.Volumetric efficiency is higher based no isothermal compression. More than 15% energy is averagely saved compared with dry type two stage compression oil-free screw air compressor, more than 25% energy is averagely saved compared with the dry type one stage compression, the running temperature is less than 50℃, and there is risk of being burned.

6.Wider pressure ranges:2-40Bar.

7.The full intelligent CNC precise machining technology and the force balance of the airend running can ensure lower noise, smaller vibration, and longer service life.

8.Averagely more than 10% air delivery is generated for the same power of water lubricating screw air compressors than the same power dry oil-free screw air compressor.


9.More simple and convenient operation, PLC intelligent control is adopted. Automatic fault detection, fault warning, maintenance reminder, fault reminder, automatic protection function. It can realize 24 hours unattended and remote-control function.

10.Copressed air is cleaner through cleaned by lubrication water, it can be directly used for breathing. The dew point of saturated compressed air is lower, and the water content of compressed air is lower by more than 25% than of an ordinary dry type oil-free screw air compressor.

11.The airend patent optimized design, large rotor, low rotary speed (within 3000r/min), without gearbox, direct connection drive, it has lower rotary speed and longer life compared with dry oil-free screw air compressor (10000r/min~20000r/min).

12.The function of automatic water exchange and automatic system cleaning can be realized, and the interior of the compressor is cleaner and sanitary.

why choose us
Longer service life of the master machine
The rotor uses asymmetrical line running at a low speed with the support of the ball bearings and roller bearings as a result. The damage and the cost are lowered and the service life is extended. Some force is counteracted by the axial force generated by the bevel gear. So the load on the bearings of the master machine is lowered.
Permanent alignment of the electromotor and the master machine
Different from the strap compressor, the SRC series compressor can integrate the electromotor with flange, shaft coupling box-gear box. and the master machine into one in such way the master machine and the electrometer are aligned forever in the transpiration. The SRC series compressors equipped with effective and fully sealed air-cooling electromotor.
