Description

Technical Field

[0001] This utility model relates to the technical field of workshop ventilation devices, and in particular to a combined cleanroom ventilation and air exchange device. Background Technology

[0002] Cleanrooms are special environments designed to control airborne pollutants and particulate matter. They are widely used in industries such as electronics, pharmaceuticals, and food. Ventilation devices play a crucial role in cleanrooms, typically removing dust, microorganisms, and other pollutants from the air through filters within ducts to ensure that air quality meets cleanroom standards.

[0003] Existing modular cleanroom ventilation systems typically involve installing filter cartridges inside the ducts to filter the air and ensure it meets standards. However, these filters need to be replaced periodically, which is cumbersome as they are located inside the ducts and require manual entry for disassembly and replacement. Therefore, this solution proposes a modular cleanroom ventilation system to address these issues. Summary of the Invention
