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.

Aluminum Alloy Piping System

Widely used for conveying compressed air, vacuum, nitrogen, and inert gases, the system is a full replacement for all traditional carbon steel pipelines. All pipe specifications are manufactured with outer diameters strictly following national standards, ensuring seamless connection with standard fittings. Made from 6063-T5 aluminum rods and formed by extrusion using alloy molds, the pipes feature an internal smooth finish and a corrosion-resistant epoxy-coated exterior — delivering clean fluid transport at a lower cost.
