Description

Technical Field

[0001] This application relates to the field of air compressor technology, and more particularly to an air filter box assembly for an air compressor. Background Technology

[0002] With the rapid development of industrial automation, air compressors, as core power equipment, are widely used in many industries such as electronics, pharmaceuticals, machinery, and chemicals. Among them, the demand for large-volume oil-free screw air compressors continues to grow due to their clean air production and stable operation. These units often require larger or more numerous air filters to ensure the purity of the intake air and avoid wear on the internal components of the main unit.

[0003] A published patent document with announcement number CN216842216U discloses an air intake air filter assembly and an air compressor unit. The air intake air filter assembly includes an air filter housing and an air filter. The air filter housing includes a housing with a receiving cavity and an air inlet. The air inlet connects the interior of the receiving cavity to the exterior of the air filter housing. The air filter is located within the receiving cavity and includes a filtered air inlet connected to the air inlet. With this configuration, during use, the air filter can draw air from the outside of the air compressor unit through the air inlet, without directly drawing air from inside the air compressor unit. Therefore, the temperature of the drawn-in air is lower, unlike when the air filter is connected to an intake valve and draws in air from inside the air compressor unit, resulting in a higher temperature intake air. In addition, the air filter is not connected to the intake valve, which makes it easy to replace. In conjunction with the above application, and compared with existing air filter boxes, many improvements are made in terms of easy filter replacement and reduced operating noise. However, filter recycling is difficult, environmental treatment is difficult, resulting in resource waste. Filtered impurities are easy to cause secondary pollution to the environment, and condensate is directly discharged, resulting in water waste. Utility Model Content
