The operating principle of an oil-free scroll air compressor is based on the relative motion of the scrolls. The key components consist of a fixed scroll and an orbiting scroll mounted eccentrically. During compression, the orbiting scroll moves in a circular path around the fixed scroll, progressively reducing the volume of the compression chambers and compressing the air. Throughout this process, there is no direct contact between the scrolls, ensuring oil-free operation. As the orbiting scroll continues its motion, the compressed air is pushed towards the center and expelled through the discharge port. Without the need for oil lubrication, this design delivers pure compressed air, making it ideal for industries with stringent air quality requirements.
Our electronic components are from the French brand Schneider. To prevent oil contamination in industries such as food, pharmaceuticals, and electronics, MINNUO’s gas compression technology operates within a sealed compression chamber. The moving and stationary scrolls come very close but do not touch, with a sealing ring in between to ensure an airtight seal. This guarantees 100% oil-free, clean air, ensuring the safety and quality of your products.
Regarding your concerns about maintenance frequency and costs, the structure of the MINNUO oil-free scroll compressor is key. With only a few main components like the motor, air filter, and compression chamber, the compressor requires no frequent part replacements or lubrication, significantly reducing your project’s maintenance costs.
If you’re facing space constraints, MINNUO has the solution. Our compressors feature a compact design with a small footprint, making them easy to install, especially in labs or confined industrial production spaces.
MINNUO oil-free scroll air compressors operate quietly, with noise levels as low as 53-65 dB(A). This ensures a quieter working environment, minimizing noise disruptions.
Choosing a MINNUO oil-free scroll air compressor not only ensures high-quality compressed air but also provides the added benefit of our professional sales team helping you significantly reduce purchasing costs.
