Purification Principle of Cleanroom Engineering
Purification principle
Airflow → Primary Air Treatment → Air Conditioning → Intermediate Efficiency Air Treatment → Fan Pressure Supply → Purified Air Supply Pipeline → High Efficiency Air Supply Port → Clean Room → Take away Dust (Bacteria) → Return Air Clip Path → Fresh Air, Primary Air Treatment .
Repeat the above process to achieve the purpose of purification.

Structural materials
1. Clean room wall and roof materials are generally made of 50mm thick sandwich color steel plates and special aluminum oxide profiles. The door adopts purifying closed doors, and the windows adopt aluminum alloy glass fixed windows.
2. Epoxy self-leveling or advanced wear-resistant plastic clean floors are used on the ground.
3. The purification ventilation pipe is made of galvanized steel sheet and uses “PEF†flame-retardant insulation board as insulation.
