AI Technical Summary
Existing gas filters are designed with a fully enclosed structure, making it impossible for operators and maintenance personnel to visually observe the filter's condition. This leads to improper filter replacement times and affects the filtration effect.
It adopts a four-stage filtration assembly, including a four-stage filter made of a transparent material, combined with a multi-stage filter and a drive mechanism, to enable visual observation of the internal structure of the filter and to determine the timing of maintenance and replacement based on the amount of impurities remaining.
It enables intuitive observation of the filter status, avoids improper filter replacement time, and improves filtration efficiency and safety.
