4) Strong stability:Under long time working, displacement and pressure stable, no crash phenomenon, low failure rate.

Why the oil free water spray screw technology is needed?

➤ Large capacity
➤ High exhaust pressure (single stage compression pressure up to 17 bar)
➤ High efficiency
➤ Close to isothermal compression
➤ Low noise
➤ Real oil-free stainless-steel screw rotor
➤ Self-lubricating
➤ Oil free ISO85730 level certificate
➤Lower application costs
➤ Lower maintenance costs
➤ “0” pollution to environment clean and safe compressed air
➤ No fault, long and stable running ability

The technical advantage water lubricating oil-free screw air compressors

Benefits of Frequency Converter:

1. With the fifth generation of oil-free screw airend technology. The compressor air end and system adopt stainless alloy, thus the technological transcendence from the copper ai rend 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. Compressed 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 air end 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.

❃ Compressed air output adjusts according to demand
❃ Lower system pressure, energy saving
❃ No load-unload cycle, no power consumption
❃ Smooth start, no peak start current
❃ Greatly reduce energy consumption

 Advantages of Kapa brand

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.

Spray

All are screw-type compressor with a modem environmental-protection paint. Its surface machining so many years after the use of castings can effectively avoid corrosion.
Shell
The modem word processing centers under the control of the technical specifications for testing. ’The most advanced machinery and the use of modem technology and constant monitoring. It applied to all processing operations. For us on the Company’s compressor quality certification of the commitments made by providing good protection.
Shaft sealing device
Equipped with dual wheels metal framework amine fluoride rubber ring to withstand certain pressures. Formation of the shaft seal can be lubricating device. Bush axis of the company’s exclusive use my special processing technology. A perfect sealing performance and long life.
Rotor
Each screw compressor is the heart of the compressor mainframe. From the latest CNC machine operators of multi-level screw fully automated manufacturing process and materials used by the higher minimum guarantee its tolerance. Reliability stronger.
