CMN250GW Micro Oil Screw air compressor Medium Pressure 3-4Mpa

Advantages of Our micro oil air compressor

1. Shaftless Design: Robust and Durable

Our micro oil air compressor features a unique shaftless design that ensures long-term use without any lubrication. This design eliminates the common issue of regular shaft seal replacements, extending the shaft seal life indefinitely.

2. Low Energy Consumption

With the largest screw design in the world and a dual-pressure chamber host, our compressor operates at an above 95% volumetric efficiency. This makes it a truly energy-efficient compressor.

3. High-Temperature Resistance

Our compressor can operate normally in a wide range of harsh environments, with temperatures ranging from -20 to 55 degrees Celsius. It can work continuously without exceeding a temperature of 92 degrees.

4. Minimal Oil Content

The high-performance host only requires a small amount of air compressor oil for effective sealing, resulting in an oil content of less than 2ppm in the produced air.

Principle of Compressed Air in Micro Oil Screw Air Compressor

Micro oil air compressors use a pair of main screws, the pressure screw and the rotating screw, to perform the compression process. These screws, usually made of high-strength alloy steel, have an exact helical shape. During the intake process, the helical shape of the pressure screw and rotating screw forms a sealed working chamber between them. As the screws rotate, the working chamber gradually expands, allowing external air to enter the working chamber via the intake. Once the air enters the working chamber, the rotation of the screws gradually reduces the working chamber, increasing the air's compression ratio and pressure. The compressed air is then pushed towards the machine's outlet. The compressed air generates heat, necessitating a cooling system to reduce its temperature. To ensure the quality of the air, the compressed air must also pass through a filtering system to remove potential contaminants and particles.

Applications of Micro Oil Air Compressor

1. Textile Industry

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

2. Glass Bottle Manufacturing

Our compressor is ideal for glass bottle manufacturing. Its low-pressure screw compressed air both saves energy and helps create perfect shapes.

3. Chemical Industry

In the chemical industry, compressed air is required for certain processes such as pressure filtering and conveying.

4. Cement Conveyance

During the cement conveyance process, compressed air can complete the delivery without causing cement dust to fly around.

About Our Company

Our company's full range of products have passed the German TUV class 0 oil-free certification, CE certification, ISO9001 certification, and TS16949 certification. We are the first company in the domestic market to use water for internal cooling and lubrication in high-end screw compressors. We were the first globally to launch a second-level compression high-pressure micro oil screw compressor with a pressure of 4.0MPa. 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.
