1.0 General Information
1.1 Description
The LABGARD® ES Model NU-565 Laminar Flow Biosafety Fume Hood/Cabinet (LFBSC) is a bench/table top model,
optionally available with a base support stand, for operation as a console model. The LABGARD® ES model NU-565 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 to airflow setpoints via a solid-state
DC motor controller with digital dual thermistor airflow sensors that provide an automatic compensation (constant volume
control) for both filter loading and line voltage variances.
The Laminar Flow Biosafety Fume Hood/Cabinet, (LFBSC) is a product resulting from the development of the "laminar flow"
principle 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-565 Bench LFBSC meets the requirements of a Class II, Type B2 since the cabinet conforms to the following
requirements:
- Maintain a minimum average inflow velocity of 100 fpm (0.51m/s) through the work access opening;
-
Have HEPA filtered downflow air drawn from the laboratory or the outside air (i.e. downflow air is not re-circulated
from the cabinet exhaust air;
-
Exhaust all inflow and downflow air to the atmosphere through a hard connection to the facility exhaust system after
filtration through a HEPA filter without recirculation in the cabinet or return to the laboratory;
- Have all contaminated ducts and plenums under negative pressure or surrounded by directly exhausted
(non-re-circulated through the work area) negative pressure ducts and plenums.
Type B2 Biosafety Fume Hood/Cabinet classified to UL 1805 may be used for work with flammable or volatile chemicals and
radionuclides required if permitted by chemical risk assessment.
