Cage changing hoods are a necessity when transferring your research animals from one location to another, during handling, or while changing their cages. Maintaining animal sterility while also preventing personal exposure to dander, fur, or other cage materials, cage changing hoods provide a safe, convenient manner of handling your animals. Hoods can come with different abilities such as HEPA filtered airflow, UV light, dual-sided access, and options with adjustable height.

| Description | The LabGard ES (Energy Saver) Model NU-677 Animal Handling Biosafety Cabinet (LFBSC) is a bench/table top model, with an integral castored support stand for operation as a console model.

The LabGard model NU-677 utilizes an Energy Saver DC ECM motor optimally determined forward curved fan for each model size/width to maximize both energy efficiency and filter loading capacity. The Energy Saver ECM motor is controlled via a solid-state DC motor controller that provides automatic compensation (constant volume control) for both filter loading and line voltage variances.
The Laminar Flow Biosafety Cabinet, (LFBSC) is a product resulting from the development of the ""laminar flow"" principle (see airflow schematic) and the application of environmental controls as required in the field of biological research or chemical containment. The LFBSC, when used with proper technique, is an effective laboratory aid in obtaining the optimum control over product quality while reducing the potential for exposure of both product and personnel to airborne biological or particulate chemical agents in low to moderate risk-hazard research and drug preparation or product operations, as prescribed by the Center for Disease Control (CDC) Atlanta, Georgia.
The NU-677 bench LFBSC is known as a Class II, Type A2 Biosafety Cabinet. This is possible since NuAire's cabinet conforms to the following requirements:
- Maintain a minimum average s inflow velocity of 100 ft/min (0.51 m/s) through the work access opening;
- Have HEPA/ULPA filtered downflow air that is a portion of the mixed downflow and inflow air from a common exhaust plenum;
- May exhaust HEPA/ULPA filtered air back into the laboratory or to the environment through an external exhaust system connected to the cabinet with a canopy connection; and
- Have all biologically contaminated ducts and plenums under negative pressure or surrounded by negative pressure ducts and plenums.
If working with volatile chemicals, the unit must be connected to an external exhaust system. Type A2 cabinets may be used for work with volatile chemicals if permitted by a chemical risk assessment....

A supply impeller creates the “push” in the The AllerGard NU-620 Dual Access Animal Transfer Station (ATS) employs a “push-pull” pattern of airflow to provide clean air in the work zone for small animal cage caging and generate suction through air slots on the work surface for allergen containment. A supply impeller creates the “push” in the transfer station by drawing air through a pre-filter and then propelling it past a supply HEPA filter and toward the work zone to create a sterile air environment. From there, a powerful DC ECM motor underneath the work zone will “pull” the air down through the air slots in the work surface to contain allergens. The air is then drawn past an exhaust pre-filter and pushed out an exhaust HEPA filter on the bottom of the unit. The NU-620 is designed as a dual-sided cabinet to provide flexibility to vivariums that have little room to maneuver their equipment.
