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.
