RABS are available in open or closed designs.
Open passive RABS utilise existing clean room overhead air supply systems to deliver HEPA filtered air over the particle process before returning air back into the clean room. In an open active RABS on board fan/filtration units supply HEPA filtered air over the critical process before returning air back to the clean room. In open RABS, the enclosure is not sealed to the equipment.
Closed RABS is a positive pressure system with on board fan/filtration units to supply HEPA filtered air over the critical process before being recirculated. All RABs can include glove ports, RTP systems, access door with interlocks and EM systems.
RABs were developed to enhance aseptic processes carried out in conventional cleanrooms
