Technical Field

[0002] An air compressor, or air compressor in full, is a device used to compress air. The main function of an air compressor is to compress air into a smaller volume, thereby generating high-pressure air, which can be used in a variety of applications, such as as a power source to drive various pneumatic tools and equipment, control robotic arms, operate valves and cylinders, etc. Commercial vehicle products are processed by CNC machine tools, machining centers, turning, milling, drilling and boring. Air compressors provide a power source for processing work and drive various pneumatic tools and equipment.

[0003] A twin-cylinder air compressor is a dual-cylinder dual-piston air compressor that achieves efficient air compression, with a high energy efficiency ratio and a wide range of compressed air pressure. During the compression process, the temperature of the gas usually rises sharply, and a twin-cylinder air compressor usually uses a fan for heat dissipation, which has a general cooling effect and is prone to cause gas overheating and combustion or damage to the air compressor. In addition, a twin-cylinder air compressor usually uses a single filter for filtration, which is not thorough and cannot remove moisture from the air, which will affect the working efficiency and service life of the compressor, so it is urgently needed to be improved.
