Dust Free Clean Rooms are essential to any manufacturing process where particulate contamination can affect the quality of goods produced. Specific clean room classifications and ISO class code descriptions provide protective guidelines and secure environments through controlled air filtration, which lowers the possibility of product contamination or large particulate interference within critical process manufacturing.

Additionally, clean room classifications require that positive pressure is continuously maintained while the cleanroom is operational. This process prevents contaminated air from flowing back within the clean air environment, allowing clean filtered air to continuously flow from clean to less-clean spaces.
