At present, oil-free air compressors are mainly improved and developed on the basis of oil-filled air compressors in two ways: one is to replace oil with water, and the other is to coat the rotor with a self-lubricating coating, because the two rotors Bearings running at high speed at the end need oil lubrication, so it is necessary to seal the lubrication space of the rotor bearing and the compression space of the rotor. It is precisely because of this high-speed sealing that the machining accuracy of the oil-free air compressor is quite high.

Common oil-free air compressor application fields:

1. Application in gold plating and copper plating industries. During the cleaning process of electroplating, it is necessary to use a compressor to remove the water on the surface of the object, and the use of an oil-free air compressor can keep the electroplating smooth.
2. Medical industry application. The medical industry, including pharmaceutical manufacturing, medical instrument air supply, etc., all need to use clean compressed air, and the air supply of the oil-free machine just meets this standard, and the oil-free machine is popular in the medical industry.

3. Laboratory application. Laboratories often use gas supply equipment to assist in the actual operation. Once the compressed air is not chaotic enough, it is easy to react with chemical substances, resulting in the failure of the actual operation, and in severe cases, it will cause a safety accident.
4. Applications in the electronics industry. The electronic industry has very precise requirements in the production of components, and every detail must not be missed.
5. Application in chemical industry. It is mainly used to improve the quality of chemical products, ensure its process and production safety, and so on.
6. Application in mining industry. Many minerals are flammable and explosive, and many of them are underground. The use of oil-free machines reduces the accident safety rate.

【Sollant】Oil-free and water-lubricated air compressor Features:

A. Efficient and long-lived host

The screw rotor of the main engine is made of ultra-corrosion-resistant navy copper alloy material, which is durable and has a long service life. The shell of the main engine is made of copper alloy material, which has good heat dissipation performance and strong corrosion resistance.

High-precision processing ensures that the screw and star wheel will not be worn due to processing and assembly problems, and the efficiency will not decrease over time.

B. 100% pure and oil-free compressed air

Sollant oil-free water-lubricated screw compressor uses pure water to seal, cool and lubricate the compression process, making the compressed air absolutely pure and pollution-free.

Under the premise of ensuring that there is no lubricating oil in the compression process, the compression efficiency is greatly improved. Compared with the dry oil-free machine with the same power, the gas output is increased by more than 15%, which is more efficient and energy-saving.

C. Imported water filter

Imported stainless steel water filter is used to efficiently filter impurities in lubricating water to ensure clean water quality.

D. Frequency conversion control, high efficiency and energy saving

The combination of frequency conversion motor and frequency converter makes Airway oil-free and water-lubricated units more energy-saving.

The inherent soft start of the frequency converter is used to avoid the current peak, the aerodynamic is more stable, the compressor pressure accuracy is below 0.1bar, and the performance is more stable.
