Since the founder Mr. B. Zimmern proposed the single-screw compression structure in 1960, CMN has brand history of over 60 years. We have formed a set of strict production management systems and processes to ensure the stability of the machines we manufactured; based on our R&D team of more than 30 people, CMN has always been a leading enterprice that focuses on innovation in the pneumatic industry. CMN has three factories and more than 20 dealers around the world, our corporate purpose has always been to focus on customer needs, continuously improve products, and realize the value of CMN.
CMN products operate stably in many factories and listed companies. Our business scope is very extensive, relying on the excellent performance of CMN oil-free screw air compressors, we have a large number of applications in industries that have high requirements for the purity of compressed air, such as pharmaceuticals, food and beverage, electronics, semiconductors and etc. CMN globally pioneering variable speed oil free PET screw air compressor, thanks to its advanced features of low noise and vibration, reduced maintenance costs, low energy consumption, has received a lot of customer praise in applications of PET blowing.
The excellent single-screw compression structure proposed by founder Mr. B. Zimmern is widely recognized as a more ideal compression structure. This structure is symmetrically balanced, providing better force balance during compression. The main screw has 12 compression chambers, completing 12 air compressions in one revolution. The air end is directly connected to the motor, resulting in higher efficiency compared to traditional twin screw air end with speed increasing gear.
During the compression process, the axial and radial forces on the main screw mutually offset, allowing it to withstand pressures of up to 40 bar. Simultaneously, the vibration and noise during operation are much lower than traditional air end.
