Tema Sinergie develops different kinds of RABS.

• Open Passive RABS: barrier system which utilizes existing cleanroom overhead air supply systems to deliver HEPA filtered air over a critical process before returning air back into the clean room.
• Open Active RABS: barrier system which has an integrated ventilation system to supply HEPA filtered air over a critical process before returning air back into the clean room.
• Closed RABS: a positive pressure system which has an integrated ventilation system to supply HEPA filtered air over a critical process, which can pass through return filters before being recirculated. Closed RABS can also be integrated with Bio-decontamination system to provide with a CGMP class A/ISO 5 environment.
