For the adaptability and limited costs, an important role is played in modular cleanrooms by the controlled contamination systems, where the boundary structure is made from an equipped ceiling supporting frame and flexible perimeter walls, formed of strips of transparent and matt plastic material. These sofwalls cleanrooms can be fixed or mobile, and are also supplied in kits, where all the components can be easily assembled, even by the end user.
The simplified bearing structure is made from a series of hollow core sections, joined to each other by screws to form the longitudinal reinforcement and the legs, with top joints and supporting plates at the bottom, or wheels.
The ceiling is formed of a series of MTF filter-ventilation modules, luminous modules and neutral modules, which are assembled together and to the longitudinal reinforcements. The lateral boundary is formed of strips of antistatic plastic material, assembled by overlapping the ends and fixed to gripper frames to form continuous wall modules, which are simply hung onto the support on the top longitudinal reinforcement and very easy to remove.
Soft cleanrooms offer numerous advantages:
• Very fast to construct for applications in current industrial processes, either temporary or permanent.
• They are virtually ideal for any use, as they can be made to any size and guarantee ISO5 class levels.
• They are easy to clean, as all the elements are simply dismantled with no need for tools, to enable perfect disinfection, and the systems can be expanded while maintaining easy access to the protected zones. In fact, in many situations they are the only possible solution.
• The same components are used as in “traditional cleanrooms”, with the same management and control methods.
