CMN90A Micro-Oil Screw Air Compressor

Benefits of Our Micro-Oil Air Compressor

1. Sealed Shaft Design

Our CMN90A Micro-Oil Screw Air Compressor boasts a sealed shaft design that is sturdy and durable. In the absence of any lubrication, traditional shaft seals do not last. However, our innovative design ensures the shaft seal never comes into contact or wears out, resolving the issue of regular replacement and effectively extending its lifespan indefinitely.

2. Low Energy Consumption

Our compressor incorporates the world's largest screw design and a dual-pressure cavity host. It compresses twice in one rotation of a spiral cavity, resulting in twelve compressions in six spiral cavities. With a volumetric efficiency of over 95%, it is a truly energy-efficient compressor.

3. High-Temperature Resistance

The CMN90A Micro-Oil Screw Air Compressor is designed to withstand various harsh environmental conditions. It can operate normally from temperatures as low as -20 degrees to as high as 55 degrees, with a continuous working temperature not exceeding 92 degrees.

4. Low Oil Content

Our high-performance host requires only a small amount of compressor oil to achieve excellent sealing results. The produced air has an oil content of less than 2ppm.

Principle of Compressed Air in Our Micro-Oil Screw Air Compressor

Our micro-oil air compressor uses a pair of main screws, namely the pressure screw and the rotating screw, to accomplish the compression process. These screws, usually made of high-strength alloy steel, have a precise helical shape. During the intake process, the helical shape of the pressure screw and the rotating screw forms a sealed working chamber between them. As the screws rotate, the working chamber gradually expands, allowing external air to enter the chamber through the intake port. Once the air enters the working chamber, the rotation of the screws causes the chamber to shrink gradually. This reduction gradually increases the compression ratio of the air, thereby raising its pressure. During this process, the air is compressed and pushed towards the outlet of the machine. The compressed air generates heat during the compression process, requiring a cooling system to lower the temperature. Simultaneously, to ensure air quality, the compressed air needs to pass through a filter system to remove potential pollutants and particles.

Applications of Our Micro-Oil Air Compressor

1. Textile Industry

Our micro-oil air compressor is widely used in the textile industry where oil-free, low-pressure compressed air is required.

2. Glass Bottle Manufacturing

Our micro-oil air compressor plays a vital role in glass bottle manufacturing. The low-pressure screw compressed air not only saves energy but also helps to create perfect shapes.

3. Chemical Industry

Our micro-oil air compressor is used in various processes in the chemical industry, such as pressure filtration and transportation, where compressed air is needed.

4. Cement Conveying

In the cement conveying process, our micro-oil air compressor not only accomplishes the conveying but also prevents cement dust from flying around, ensuring a clean and safe working environment.

About Our Company

Our company's full range of products has passed German TUV Class 0 Oil-Free Certification, CE Certification, ISO9001 Certification, and TS16949 Certification. We are the first domestic company to use water for internal cooling and lubrication of high-end screw compressors. We also pioneered the launch of a second-stage compression high-pressure micro-oil screw compressor with a pressure of up to 4.0MPa globally. Furthermore, we developed the world's first 4.0MPa pressure oil-free screw compressor and the world's first 1.25MPa pressure oil-free vortex compressor.
