Description

Technical Field

[0001] The utility model relates to the technical field of magnetic suspension air compressors, in particular to a magnetic suspension air compressor filtering device. Background Art

[0002] The high-speed magnetic levitation blower air intake filter system currently uses simple flat filter cotton to purify the imported air, which has low filtering effect and small filtering area. In addition, the filter cotton has a complicated process when replacing, and the filter frame and filter cotton need to be disassembled. Especially after a period of use, impurities will make the filtering effect of the filter cotton worse, thereby affecting the air intake effect of the blower, resulting in poor use of the air compressor. On the other hand, when the air compressor is running, the gas temperature in the air compressor will be too high, affecting the subsequent use stability of the compressed gas. Therefore, it is necessary to filter the compressed gas to reduce the temperature of the compressed gas to meet the needs of subsequent actual use. Therefore, a magnetic levitation air compressor filter device is needed. Utility Model Content
