NuAire LabGard NU-813-600 6' Class I HEPA-Filtered Containment Enclosure

The NuAire LabGard NU-813-600 is a six-foot Class I containment ventilated enclosure designed to protect laboratory personnel and the surrounding environment during procedures involving airborne particulates, powders, and aerosols. Available used and refurbished from American Instrument Exchange, this large-capacity enclosure combines controlled inward airflow, an integrated blower motor, and an included HEPA exhaust filter to provide a self-contained containment workstation for laboratory applications that require personnel protection without product protection.

Unlike a conventional chemical fume hood, the NuAire NU-813-600 is designed primarily for particulate and aerosol containment. Room air enters through the front access opening, moves across the work area, and passes through the included HEPA filter before being discharged. In its standard recirculating configuration, filtered air is returned to the laboratory without requiring external exhaust ductwork.

The NU-813-600 measures approximately 72" W × 29" D × 54" H externally and provides an interior work area measuring approximately 70.4" W × 24" D × 28" H. Its six-foot width makes it particularly useful for laboratories requiring a spacious containment workstation for powder handling, pharmaceutical preparation, sample processing, and other appropriate procedures.

Overview of the NuAire LabGard NU-813-600

The NuAire NU-813-600 belongs to the LabGard series of containment ventilated enclosures developed for laboratory procedures that generate potentially hazardous airborne particulates.

Its Class I configuration draws room air into the enclosure through the front access opening, helping prevent particles and aerosols generated during laboratory work from escaping into the operator's breathing zone.

The integrated blower motor and included HEPA filter allow the enclosure to function as a self-contained, recirculating containment workstation for appropriate applications. This eliminates the need to purchase a separate blower or filtration system for standard operation.

The large six-foot workspace distinguishes the NU-813-600 from smaller powder containment and balance enclosures. It provides room for multiple instruments, sample containers, weighing equipment, and laboratory accessories while maintaining a dedicated containment environment.

This combination makes the NU-813-600 suitable for pharmaceutical research, environmental testing, laboratory animal research, analytical chemistry, and other facilities requiring localized particulate containment.

Class I Personnel and Environmental Protection

The primary purpose of the NU-813-600 is to protect laboratory personnel and the surrounding environment from airborne contaminants generated during appropriate procedures.

The enclosure draws room air inward through its front access opening at a nominal velocity of 80 feet per minute. Air moves through the work area and into the exhaust system, where the included HEPA filter captures airborne particles before discharge.

NuAire specifies HEPA filtration efficiency of 99.995% at 0.3 microns for the NU-813 series.

Because unfiltered room air enters the work area, the NU-813-600 does not provide the product protection associated with a Class II biosafety cabinet. It should not be selected for aseptic procedures requiring protection of sensitive samples from ambient laboratory contamination.

Integrated Blower Motor and Included HEPA Filter

A significant advantage of this NuAire NU-813-600 is that both the blower motor and HEPA exhaust filter are included with the enclosure.

The integrated motorized impeller draws air through the front opening, across the work area, and through the HEPA exhaust filter. This creates the inward airflow necessary for personnel containment while removing airborne particulates from the exhaust stream.

In its standard recirculating configuration, filtered air is discharged back into the laboratory. The enclosure is designed to operate at approximately 390 CFM at its nominal 80 fpm inflow velocity.

Because the blower and HEPA filter are already included, laboratories do not need to source these major components separately.

The installed HEPA filter should undergo appropriate integrity testing before the enclosure is placed into hazardous service, and airflow performance should be verified after installation.

AeroMax Controls and Airflow Monitoring

The NU-813 series incorporates NuAire's AeroMax electronic control system, which provides an interface for enclosure operation and airflow-related monitoring.

Pressure-based monitoring helps identify changes in operating conditions that may affect containment performance.

This is particularly important in Class I enclosures because effective personnel protection depends on maintaining appropriate inward airflow through the front access opening.

The integrated control system provides a convenient means of operating and monitoring the enclosure as part of routine laboratory procedures.

Bag-In/Bag-Out HEPA Filter Design

The LabGard NU-813 incorporates a bag-in/bag-out HEPA filter removal system intended to reduce personnel exposure during filter servicing.

As the included exhaust filter captures airborne particulates over time, resistance to airflow may increase. Periodic evaluation of filter performance is therefore important to maintaining appropriate containment conditions.

The bag-in/bag-out design helps facilitate controlled removal of contaminated filtration media while reducing the potential for maintenance personnel to contact collected particles.

The inclusion of the HEPA filter makes this refurbished unit particularly attractive to laboratories seeking a complete containment enclosure rather than an enclosure requiring major filtration components to be purchased separately.

Spacious Six-Foot Work Area

The NU-813-600 provides an interior work area measuring approximately 70.4 inches wide, 24 inches deep, and 28 inches high.

This generous workspace can accommodate multiple sample containers, laboratory instruments, weighing equipment, and other apparatus required for procedures involving powders or aerosols.

The enclosure incorporates an epoxy resin work surface that provides a durable platform for laboratory operations and facilitates routine cleaning.

Transparent polycarbonate panels provide visibility into the work area, while the front viewing window can be raised for equipment loading and cleaning.

During normal operation, the standard access opening is eight inches high. The viewing window can be opened to approximately 24 inches for loading equipment, but the larger opening is not intended for normal containment operation.

Common Applications

The NuAire NU-813-600 can support laboratory procedures involving airborne particulates and aerosols when the materials and activities are appropriate for Class I containment.

Potential applications include pharmaceutical powder handling, dry reagent preparation, analytical sample processing, laboratory animal necropsy procedures, environmental sample preparation, weighing operations, and selected microbiological research procedures.

The enclosure may also be useful for laboratories performing repetitive particulate-generating tasks that would otherwise expose personnel to airborne dust or aerosols on an open laboratory bench.

Application suitability should always be determined through an appropriate risk assessment considering the materials, quantities, procedures, and required containment performance.

Ideal Laboratory Environments

The NU-813-600 is suitable for pharmaceutical research and development laboratories, biotechnology facilities, environmental testing laboratories, analytical chemistry laboratories, laboratory animal research facilities, industrial quality control departments, and university research laboratories.

Its six-foot width is particularly advantageous when several instruments or multiple sample preparation activities must be accommodated within one contained workspace.

Recirculating Operation and Installation Requirements

One of the primary advantages of this NU-813-600 is its integrated blower and HEPA filtration system.

Unlike a conventional ducted chemical fume hood, the enclosure does not require a separate blower motor or external building exhaust connection for appropriate recirculating particulate applications.

The included blower draws contaminated air through the enclosure and HEPA filter before returning filtered air to the laboratory. This configuration can simplify installation and reduce the expense of adding dedicated containment equipment to an existing facility.

However, laboratories must evaluate whether recirculating operation is appropriate for the materials being handled. Procedures involving chemical vapors, gases, or hazards that cannot be adequately controlled by HEPA filtration may require a different exhaust arrangement or containment system.

The enclosure should be installed on a suitable supporting surface capable of accommodating its approximately 500-pound net weight. If a separate stand is required, its inclusion should be confirmed before purchase.

Final airflow and HEPA filter integrity testing should be completed before the enclosure is placed into hazardous service.

Choosing a Class I Enclosure vs. a Class II Biosafety Cabinet

Class I and Class II biosafety cabinets provide different levels of protection.

The NU-813-600 is designed primarily for personnel and environmental protection. Room air enters through the front opening and passes through the enclosure before being HEPA filtered.

A Class II biosafety cabinet provides personnel, product, and environmental protection through controlled inward airflow, HEPA-filtered downward airflow, and HEPA-filtered exhaust.

For procedures involving particulate or aerosol hazards that do not require product protection, a Class I enclosure may be an appropriate and economical choice.

For sterile cell culture, aseptic manipulations, and other procedures where protection of the sample from ambient contamination is essential, laboratories should consider an appropriate Class II biosafety cabinet.

Class I Enclosure vs. Chemical Fume Hood

Although the NU-813-600 and a conventional chemical fume hood both draw air away from the operator, their intended applications differ.

The NU-813-600 is primarily designed for particulate and aerosol containment using HEPA filtration.

A conventional chemical fume hood is generally designed to capture and exhaust hazardous chemical vapors and gases.

The NU-813-600 should not be treated as a general-purpose ductless chemical fume hood simply because it recirculates filtered air. HEPA filtration alone does not provide adequate protection from most volatile chemical vapors.

Refurbishment and Testing

This NuAire LabGard NU-813-600 is inspected and refurbished by American Instrument Exchange before shipment.

Our technicians inspect the enclosure, integrated blower motor, included HEPA filter, viewing window, lighting, controls, and other operating components as applicable to the individual unit. The enclosure is cleaned and prepared for shipment following the refurbishment process.

The included HEPA filter should undergo appropriate integrity testing after installation, along with airflow testing and any required containment certification, before the enclosure is used for hazardous procedures.
