At the heart of the oil-free air compressor is the outstanding two-stage compression mainframe. The rotor is finely machined through twenty processes to achieve unparalleled accuracy and durability of the rotor line. High-quality bearings and precision gears are installed inside to ensure the coaxiality of the rotor, so that the rotor fits accurately, thus maintaining long-lasting, efficient and reliable operation.
Minnuo, as a professional manufacturer of oil-free air compressors, is designed to provide 100% oil-free air for critical applications, ensuring the highest standards of air quality and performance. Our oil-free compressed air solutions are designed to provide zero risk of contamination, improved energy efficiency and long-term reliability to meet the sensitive needs of various industries such as pharmaceutical, food and beverage and electronics, where the possibility of any oil contamination in the production process cannot be tolerated.
Our main oil-free air compressors are divided into: oil-free screw air compressors and oil-free scroll air compressors. At present, all of them have realized the efficacy of mute and energy saving, and have obtained the oil-free guarantee ISO85730 standard certificate, you can rest assured that you can choose our products.
Oil-free screw compressor is divided into oil-free single-screw compressor and oil-free twin-screw compressor, the use of two-stage screw rotor compressed air, through the water-gas separator to get rid of water in the compressed air. At the same time, because there is no oil injection cooling, generally equipped with pre-cooler, intermediate cooler, after-cooler to cool down the compressed air to achieve the required exhaust temperature. In the rotor shaft through the excellent performance of the shaft seal to prevent lubricant leakage into the compressed air, in order to achieve the real oil-free.
Oil-free water-lubricated screw air compressors are efficient, reliable, and use water instead of oil for lubrication, making them ideal for applications requiring high air quality.
