Compounding Aseptic Containment Isolator Restricted Access Barrier System

USP 800 Compliant | Sterile Hazardous Compounding | Negative Pressure Recirculating | ISO Class 5 Environment

The NU-NR800 is a Compounding Aseptic Containment Isolator (CACI) composed of a stainless-steel enclosure and polycarbonate front window with gloves that provides 20 air changes per minute of ISO Class 5 HEPA filtered air for the preparation of sterile but hazardous drugs. The isolator is sub-divided into an interchange chamber that is kept at a stronger negative pressure than the adjoining work chamber, which is itself at negative pressure to the room. This cascade of pressure simultaneously prevents contamination into the interior and the escape of hazardous material from it. A sliding door and work tray allow the passage of items within the isolator before compounding, while the hinged front window allows easy access for maintenance. Standard minihelic gauges display the pressure in both the work and interchange chambers while the standard PharmaGard™ digital monitor alerts the operator when the work chamber negative pressure has departed from its acceptable parameters. Separately available exhaust canopy and exhaust alarm accessories allow connection to an external exhaust blower.

The FlowGard control panel features one minihelic gauge for each chamber. This allows the user to quickly monitor and compare the negative pressures in each one and ensure that the correct differential is being maintained between the work and interchange chambers. A PharmaGard digital monitor activates an alarm if the negative pressure in the work chamber departs from normal parameters. Membrane buttons turn on the blower and lights.



The entire compounding aseptic containment isolator is maintained at negative pressure compared to the room in which it is installed in order to protect against the escape of particulates. Inside, a downflow of 45-55 fpm (0.23-0.28 m/s) of HEPA filtered air creates 20 air changes per minute and an ISO class 5 environment. The interior is sub-divided into an interchange area that is kept at a stronger negative pressure than the adjoining work area in order to protect the sterile drugs compounded inside the work area from contamination floating in. Most downflow air is re-filtered and recirculated but about 5% is exhausted to ensure negative pressure.

Restricted Access Barrier System Sliding Work Tray

Improved Workflow

Sliding Work Tray

Located in the transfer compartment, the sliding work tray provides a seamless transition when entering compounding materials into the work zone. The stainless steel work tray is mounted on ball bearing brackets to smoothly enter compounding materials into the sterile work area.

NuAire RABS feature three IV bar height locations

Designed for Multiple Technicians

Three IV Bar Locations

NuAire RABS comes standard with three IV Bar height locations allowing different pharmacy technicians to comfortably work within the CAI or CACI.

Restricted Access Barrier System Counter Balance Interior Window

Separating Environments

Counter Balance Inner Transfer Window

The transfer window counterbalance is isolated from the sterile product inside the inter-chamber wall. The window moves easily up or down with one finger. A security lock featured on CACI units ensures the inner transfer door remains locked if the outer door is open.



NuAire offers the NU-916-797 exhaust transition to enable pharmacies to connect the NU-NR800 unit to an external exhaust blower as required by the USP 800 guidelines and still enjoy the cost advantages of a canopy connection. As a recirculating design, the NU-NR800 requires much less exhaust volume than a total exhaust model and thus reduces not only the cost of installation but also lifetime operational costs for your pharmacy.

Note: This accessory is sold separately. The suitableness of a recirculating model for compounding hazardous drugs must be evaluated by a qualified risk assessment.
