CMN11A Micro-Oil Screw Air Compressor: A Comprehensive Review

The Advantages of CMN11A Micro-Oil Screw Air Compressor

1. Shaftless Design, Durable and Long-lasting

The CMN11A Micro-Oil Screw Air Compressor is equipped with a shaftless design, which allows for long-term usage even under oil-free conditions. No need for frequent replacements, as this innovative design ensures the shaft seal's lifespan is virtually unlimited.

2. Low Energy Consumption

Our compressor boasts the world's largest screw design and a double pressure chamber operating host. With each revolution, the screw compresses air twice in one spiral chamber and twelve times across six spiral chambers. This results in a volumetric efficiency of over 95%, making it a true energy-saving compressor.

3. High-Temperature Resistance

Our compressor can operate under various harsh environmental conditions, with operating temperatures ranging from -20 to 55 degrees Celsius, and a continuous working temperature not exceeding 92 degrees.

4. Low Oil Content <2ppm

Our highly efficient host only needs minimal air compressor oil to achieve an excellent seal effect. The air output has an oil content of less than 2ppm, ensuring high-quality, clean air compression.

Principle of Compressed Air in CMN11A Micro-Oil Screw Air Compressor

Our Micro-Oil Air Compressor uses a pair of main screws, the pressure screw and the rotating screw, to accomplish the compression process. These screws are typically made of high-strength alloy steel and have a precise 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 through the intake port. Once the air enters the working chamber, the rotation of the screws causes the working chamber to gradually reduce. This reduction gradually increases the air's compression ratio, thereby increasing the air's pressure. During this process, the air is compressed and pushed towards the machine's outlet. The compressed air generates heat during the compression process, so a cooling system is needed to reduce the temperature. At the same time, to ensure air quality, the compressed air needs to be cleaned through a filtering system to remove potential pollutants and particles.

Applications of Micro-Oil Air Compressor

1. The textile industry uses oil-free, micro-oil low-pressure compressed air in many places.

2. Various types of glass bottles rely on low-pressure screw compressed air for molding, saving energy and creating perfect shapes.

3. Some processes in the chemical industry, such as pressure filtration and transportation, require compressed air.

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