Four-cylinder compression with air-cooled intercoolers , low-speed , heavyduty,bnergy-efficient, durable, the compressor is designed with adisplacement of 0.7-2.0m*min and a pressure of 3.5-15.0MPa; It can be designed as a multi-unit integrated skid-mounted design withninimal noise and vibration,and simplified installation, according tocustomer needs:The post-processing can be equipped with a stainless steelplate heat exchanger refrigerant dryer, which achieves lower pressure dewpoints, a three-stage high-precision filter, and a centralized stainless steeldrain pipeline to ensure the cleanliness of the cutting processes.

The energy saving of the water-lubricated twin-screw oil-free compressor is continuous and stable, the rotor is not worn, the clearance at the exhaust end is not changed, and the performance index is not attenuated; There is no increase in the resistance of the "oil separation core", and the energy consumption is not increased. The water-lubricated twin-screw oil-free compressor has strong environmental adaptability; Not afraid of high temperature environment, not afraid of high humidity environment, low vibration, low noise, low unit temperature;

“Air cend” Magnetic levitation air compressors are innovative air compression devices featuring core magnetic suspension bearing technology, enabling frictionless rotor operation and eliminating traditional oil lubrication. This results in 100% oil-free output air, significantly enhancing air purity. The technology drastically reduces mechanical friction losses and, combined with efficient variable frequency drive, delivers substantial energy savings. Furthermore, the magnetic suspension design achieves ultra-low operating noise and vibration, considerably improving the working environment. Due to their oil-free nature, energy efficiency, low noise operation, high reliability, and minimal maintenance costs, magnetic levitation air compressors are ideally suited for industries like electronics, pharmaceuticals, food and beverage, automotive manufacturing, and precision machining, where high air quality, ultimate efficiency, and environmental protection are paramount.
