37KW 8bar Oil-free screw air compressor

100% Oil-Free Compressed Air – Pure, Efficient, Reliable

Superior Efficiency with Water-Lubricated Technology

Our oil-free screw air compressors use purified water for sealing, cooling, and lubrication, significantly enhancing efficiency. Compared to traditional dry oil-free compressors with the same motor power, our water-lubricated system delivers 15% higher air output while drastically reducing energy consumption.

With only water, air filters, and water filters as consumables, maintenance costs are minimal—ensuring long-term savings without compromising performance.

Zero Oil Contamination – 100% Pure Air for Critical Industries

In industries where even the slightest oil contamination can lead to production shutdowns, product damage, or reputational harm, our oil-free screw compressors provide absolute safety.

Ideal for:
✔ Food & Beverage – Ensures hygienic air for processing and packaging.
✔ Pharmaceutical & Medical – Eliminates contamination risks in sterile environments.
✔ Electronics & Precision Manufacturing – Protects sensitive components.
✔ Painting & Powder Coating – Prevents defects in surface finishes.
✔ Textile & Packaging – Maintains product purity and consistency.

Since no lubricating oil enters the compression chamber, and purified water continuously cleans the air, the output is 100% oil-free, contaminant-free, and pollution-free.

Built for Performance & Durability

• High Precision & Wear Resistance – Engineered for long service life.

• Low Noise & Smooth Operation – Ideal for noise-sensitive environments.

• Energy-Saving & Stable Output – Reduces operational costs.

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.
