Closed, aseptic isolators or Restricted Access Barrier Systems (RABS) are proposed for sterile applications.

Fully customized Aseptic Isolators that provide a total separation of the product from external contamination during processing. Aseptic isolators are routinely used within the pharmaceutical industry.

A sterile isolator allows avoiding the use of sterile cleanrooms, reducing the sterile volume around the process. Turbulent or unidirectional airflows can be adopted for ventilation.

FPS offers a range of totally contained aseptic solutions that covers the following applications:

  • Sterility testing
  • Aseptic filling lines
  • Vessel charging of sterile products
  • Dispensing
  • Sterile milling and micronization
  • Vessel discharge of sterile products.

Most applications include an integrated decontamination system (VPHP generator).


The RABS is the right choice for flexible and secure production in existing cleanrooms. A RABS can be designed as open or closed system (i.e. for toxic products), and can be active or passive. Each RABS is engineered and optimized according to the process requirements.

FPS offers:

  • Active RABS, complete with HVAC and T/RH control
  • Passive RABS, with control integration for process machine (filling line)

Retrofitting of existing units can be achieved in a relatively short period of time.
