Restricted Access Barrier System (RABS) Retrofits for Existing Equipment


With ever-increasing regulations, incorporation of the latest barrier technology into your aseptic filling operation can increase product and operator safety.
A Restricted Access Barrier System (RABS) is the barrier and processes that improve aseptic quality in comparison to clean room production. RABS is more than just a barrier around a machine – it is a system. RABS barriers can be arranged in a variety of different configurations, and how an end user uses this system can be driven by a variety of factors. Examples of RABS configurations include; passive RABS, active RABS, passive closed RABS, and active closed RABS (figure 1).

Upgrading to a RABS System
Bosch has been the industry leader in the design and construction of barrier systems for over 20 years. Bosch RABS upgrades are flexible and customizable to specific user needs. Each project begins with an on-site survey to understand machine fitment and ergonomics. 3D design models are created and an equipment mock up is also possible. Projects are managed from initial design to installation in order to minimize production downtime.

When developing a RABS solution, there are many items in the aseptic filling operation to consider, including but not limited to:

  • Current equipment quality and points of intervention
  • Glove ports and interlocked door monitoring
  • Laminar flow solutions
  • Clean design with particle trap elimination
  • Commodity and component supply methods (i.e. rapid transfer ports)
  • Environmental monitoring
  • Controls and safety integration
  • Glove testing equipment
  • Validation packages
