Description

Technical Field

[0001] The utility model relates to the technical field of air duct filtering, in particular to an air duct filtering structure for a sterile workshop. Background Art

[0002] The air quality of the sterile workshop is crucial to the production process and product quality. Through air duct filtration, it can help maintain the air quality in the clean workshop, maintain the stability and consistency of the production environment, and ensure that the product meets the relevant standards and requirements; by setting filters in the air duct of the sterile workshop, particles and particulate matter in the air can be effectively removed. This helps to keep the air inside the sterile workshop clean, reduce the pollution sources in the air, and thus reduce the risk of product contamination.

When the filter inside the air inlet needs to be disassembled for replacement or cleaning, the process takes a long time and the air duct cannot perform normal filtering operations, which seriously affects the working efficiency of the air duct. Therefore, it is urgently needed to be changed. Utility Model Content
