Advanced scroll compression technology
The unique working principle of scroll compression technology gives CHINAMFG KC series compressors unique energy efficiency advantages. The air compression process is achieved by the mutual movement of the fixed scroll and the moving scroll. Air enters from the outer side of the nose. Once the air is sucked in, the moving scroll closes the air inlet. As the moving scroll moves When rotating, the air is gradually compressed, and continuous compressed air is discharged from the center of the static scroll.
This process is repeated continuously, so that the discharged air is always continuous without fluctuations.
DEHAHA series oil-free scroll air compressor adopts leading technology from Germany, condensing many years of industry experience and professional technology, with excellent design and configuration to ensure the high reliability of our products.

What Is an Oil-Free Scroll Air Compressor?
An oil-free scroll air compressor is a type of compressor that utilizes a scroll mechanism to compress air without the need for lubricating oil. Here’s a detailed explanation:
Working Principle:
An oil-free scroll air compressor consists of two spiral-shaped scrolls, typically referred to as the stationary scroll and the orbiting scroll. These scrolls are positioned eccentrically to each other, creating crescent-shaped compression chambers.
As the orbiting scroll moves in a circular motion within the stationary scroll, the crescent-shaped compression chambers decrease in volume. This reduction in volume compresses the air trapped within the chambers, resulting in the pressurization of the air.
Oil-Free Operation:
- No Lubricating Oil: Unlike other compressor types, such as reciprocating or rotary screw compressors, oil-free scroll compressors do not rely on lubricating oil for sealing or cooling purposes. The scrolls are designed with precision tolerances and mating surfaces that allow them to operate without any oil lubrication.
- Dry Compression: The absence of lubricating oil in the compression chambers ensures that the compressed air remains free from oil contaminants. This makes oil-free scroll compressors suitable for applications that require clean, oil-free air, such as in medical, pharmaceutical, laboratory, and food processing industries.
Advantages:
- High Efficiency: Oil-free scroll compressors are known for their high efficiency due to the continuous compression process. The scroll design minimizes internal leakage and improves volumetric efficiency, resulting in reduced energy consumption and operating costs.
- Compact and Quiet: Oil-free scroll compressors are compact in size and have fewer moving parts compared to other compressor types. This compact design not only saves space but also contributes to quieter operation with lower noise levels.
- Low Maintenance: Since oil-free scroll compressors do not require oil changes or regular lubrication, their maintenance requirements are significantly reduced. This can lead to cost savings and less downtime for maintenance activities.
- Reliability: The scroll mechanism in oil-free scroll compressors operates smoothly and without metal-to-metal contact, resulting in reduced wear and tear. This enhances the compressor’s reliability and longevity, providing consistent performance over an extended period.
Applications:
Oil-free scroll compressors are commonly used in various applications where clean, oil-free compressed air is essential. Some typical applications include:
- Medical and dental air supply
- Pharmaceutical manufacturing
- Laboratory air systems
- Food and beverage processing
- Electronics manufacturing
- Printing and packaging industries
Overall, an oil-free scroll air compressor offers efficient, oil-free compression, compactness, low maintenance, and reliability, making it a suitable choice for applications that demand clean air and require a reliable source of compressed air.
