      Since 2017, we have proudly offered a ten-year warranty policy on our compressors in China. We deeply understand that even a single production halt due to compressor failure could lead to significant losses. That’s why our engineering and production process are guided by the “ten-year failure-free” standard, assuring each air compressor is designed and built to the highest standards of durability and reliability.
      
                
      
                
      
                    
      Energy-saving
      
                    
      We are the forerunner of energy-saving technologies in the industry. We launched our first VSD oil-injected air compressor in 2004 and drafted China’s industry standard for VSD Oil-injected and PM VSD Screw Air Compressors. In 2015, we launched two-stage PM VSD air compressors. Our products have won the "Energy Efficiency Star" awarded by the Ministry of Industry and Information Technology (MIIT) for five consecutive years. In 2024, we were honored as "Compressed Air System Energy Saving Outstanding Contributor" by the China General Machinery Industry Association (CGMA), the only Chinese air compressor manufacturer awarded along with multinational corporates.

      Our service motto is to "put customers' interests first and take pride in delighting customers"! In order to maximize customer return in the ten-year life cycle of air compressor, we suggest to have “comprehensive maintenance” every 3,000h. Regular maintenance of our air compressors and post-treatment system can ensure the long-lasting efficiency and reliability of installed units.
