Purification workshop's purification principle

Hello, purification workshop's purification principle is mainly like this. The air flow goes through the process of primary air treatment-air conditioning-intermediate air treatment, pressurized air supply by the fan, reaching the efficient air supply outlet-clean room-dust removal-return air duct-fresh air through the purification air supply pipeline, and then repeating the process of effective air treatment, which is roughly the process. Of course, there will be some differences in details or processes in different industries. I hope it helps you!
