Although often declared as secondary process, storage and transportation of materials and products in the production process take an important role. It must be noticed that particles can settle on the surface during prolonged storage even within cleanroom. Sensitive materials may be damaged due to moisture and oxygen in the air. The protection against contamination of the products is required while transportation by rooms with lower purity class.
Clean air-purged transport trolleys are used for the internal transportation and storage of materials and components under clean conditions.
