LabGard ES Air NU-543 Class II, Type A2 Biological Safety Cabinet

By: Nuaire

LabGard Air offers the very best in personnel, product, and environmental protection through the use of airflow probe to monitor and maintain real time airflow and displays airflow speeds on the OLED interface. The ability to choose up to three (3) different access opening heights allows our customers the option to select a larger access opening to improve technician movement and reach; select a smaller access opening to lower your total cost of ownership; or select somewhere in-between to get the best of both heights.

FlowGard™ Electronic Control System

FlowGard™ ECS offers a user friendly design with rich functionality. Basic cabinet functionality (Motor Blower, Lights, UV Light, Outlet(s), Alarm Silence) is controlled through easily identifiable buttons. Cabinet's inflow and downflow air speed is displayed on the FlowGard™ ECS OLED display screen. Airflow performance is monitored and controlled via intelliFlow™ - A Digital Pressure Monitor, the same technology used by service professional who certify your cabinet at minimum once a year.

Ultra High Efficiency Motor

A single ultra-high efficiency ECM motor with a properly sized fan blade minimizes energy usage while extending the life of filters. LabGard offers the lowest total cost of ownership compared to other models.

HEPEX Zero Leak Airflow System

All LabGard positive pressure plenums are surrounded by a vacuum relative to the room. Meaning in the event of a leak via gasket failure, all contaminated air in the plenum is still forced through HEPA filtration. The HEPEX™ system also works to provide true laminar airflow by evenly distributing plenum air over the supply HEPA filter. The flexible design eliminates any vibration transfer from the motor blower as well as creates a serviceable work environment for Certifiers after decontamination.


Safety is Priority Number 1:

True Laminar Airflow

Unidirectional airflow moving along parallel flow lines at a constant velocity of 60 fpm (0.30 m/s) minimizes air turbulence within the work zone lessening the chance for cross contamination.

Dynamic Air Barrier

A strong inflow air velocity of 105 fpm (0.53 m/s) over an aerodynamic airfoil creates a dynamic air barrier offering maximum personnel protection.
