KUNFENG® offers a complete line of cleanroom cranes designed to meet the needs of the pharmaceutical, food and semiconductor industries.
Do you know what’s the standard of clean room? And how can we made clean lifting possible?
Cleanrooms are classified according to the number and size of particles permitted per volume of air. ISO 14644-1 and ISO 14698 are non-governmental standards developed by the International Organization for Standardization (ISO). The former applies to clean rooms in general (see table below).
