Restricted Access Barrier System (RABS)

RABS - provides an enclosed environment that meets clean air requirements by utilizing rigid partitions and airflow to separate its interior from its surroundings.

Features:

Active RABS: built-in HEPA-filtered air supply system

Passive RABS: air supply by ceiling-mounted HEPA filters.

Open RABS: the barrier has vents that allow air movement from Class A to Class B area.

Closed RABS: air movement occurs within the system.

The main characteristics of active open RABS are:

A physical and aerodynamic barrier with unidirectional airflow with glove devices;

2. the conditions in the work area correspond to clean areas of type A (ISO class 5);

3. the conditions in the environment correspond to type B clean zones (ISO class 7);

4. decontamination is performed manually with a sporicidal agent (with operator access to the working area);

5. air return to the surrounding area;

6. RABS may be opened during operation (under certain conditions).
