[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. The function of the air compressor filter element is to allow the oil-containing compressed air generated by the main engine to enter the cooler, and then enter the oil-gas filter element for filtration after mechanical separation, intercept and aggregate the oil mist in the gas, and form oil droplets that are concentrated at the bottom of the filter element and return to the compressor lubrication system through the oil return pipe, so that the compressor can discharge purer and higher-quality compressed air. During the use of the air compressor filter element, the air entering the filter element needs to be filtered to reduce the filtration pressure of the air compressor filter element.

[0003] When filtering the air intake of an air compressor, dust is easily accumulated in the filter structure during long-term use, causing blockage, which in turn affects the air intake stability of the air compressor. At the same time, it is not convenient to seal the air compressor when it is not in use. Therefore, it does not meet the existing needs. We propose a modular filtering device for air compressors.
