CMN75D Micro Oil Screw Air Compressor Low Pressure

The Advantages of Our Micro Oil Air Compressor

• No Shaft Seal Design, Robust and Durable

  Our innovative no shaft seal design, which never contacts nor wears out, eliminates the need for regular replacement, extending the shaft seal life indefinitely even under lubrication-free conditions.

• Low Energy Consumption

  With the world's largest screw design and twin-pressure cavity host, our compressor achieves a volumetric efficiency of over 95%, making it a truly energy-efficient compressor.

• High-Temperature Resistance

  Our compressor can operate normally in a variety of harsh environmental conditions, with an operating temperature range of -20 to 55 degrees Celsius and a continuous operating temperature not exceeding 92 degrees.

• Oil Content Less Than 2ppm

  Our high-efficiency host only needs a small amount of air compressor oil to achieve excellent sealing effects, resulting in an air production oil content of less than 2ppm.

The Principle of Compressed Air of Our Micro Oil Screw Air Compressor

Micro oil air compressor uses a pair of main screws, namely the air pressure screw and the rotating screw, to complete the compression process. These two screws are usually made of high-strength alloy steel and have a precise helix shape. During the intake process, the helical shape of the air pressure screw and the rotating screw forms a sealed working chamber between them. As the screws rotate, the working chamber gradually expands, causing external air to enter the working chamber through the intake port. Once the air enters the working chamber, the rotation of the screws causes the working chamber to gradually shrink. This shrinkage gradually increases the air compression ratio, thereby increasing the air pressure. In this process, the air is compressed and pushed towards the outlet of the machine. Compressed air generates heat during the compression process, therefore a cooling system is needed to lower the temperature. Meanwhile, to ensure the quality of air, compressed air needs to be cleaned through a filtering system to remove potential pollutants and particles.

Applications of Our micro oil air compressor

• Textile Industry

  In the textile industry, oil-free and micro-oil low-pressure compressed air is used in many places.

• Glass Industry

  Various types of glass bottles are blown into shape by low-pressure screw compressed air, which not only saves energy but also blows out perfect shapes.

• Chemical Industry

  Some processes in the chemical industry, such as pressure filtration, transportation, need compressed air.

• Cement Industry

  In the process of cement transportation, compressed air can complete the transportation without causing cement to fly.

About Our Company

Our company's full range of products has passed German TUV class 0 oil-free certification, CE certification, ISO9001 certification, TS16949 certification. We are the first domestic company to use water for internal cooling and lubrication of high-end screw compressors and the first to launch a second-stage compression high-pressure micro-oil screw compressor with a pressure of 4.0MPa worldwide. We then developed the world's first 4.0MPa pressure oil-free screw compressor and the world's first 1.25MPa pressure oil-free vortex compressor.
