Closed Restricted Access Barrier Systems

Closed Restricted Access Barrier Systems (cRABS) air handling is dedicated to the system and provides down-flow air which is circulated inside physical barriers, together with the provision of make-up fresh air and a ducted exhaust system.

Features

  • Less influence on airflow in the surrounding environment.
  • Rigid wall enclosure provides full physical separation of the aseptic processing operations from operators.
  • Unidirectional airflow systems provide a grade-A environment to the critical areas.
  • cRABS puts positive pressure on the environment.
  • Doors are controlled by safety switches. An alarm and stopping aseptic processing signal will be triggered when wrongly opening doors during aseptic production.
  • Gloves are used to access all the process areas needed for intervention with doors closed.
  • RTP and other connections or interfaces under aerodynamic barrier protection are used for transfer procedures.
  • Environment monitoring devices can be integrated according to the customer’s requirement, such as reserving the mechanical and electrical ports for the particle counter and microbe sampler.
  • An Integrated H2O2 vapor decontamination system is an optional function of the cRABS.
