LabGard ES (Energy Saver) NU-430 Class II, Type B2 Biosafety Cabinet

By: Nuaire

The LabGard ES 430 Total Exhaust Biological Safety Cabinet may be used for work with non-flammable or explosive volatile chemicals and radionuclides by providing personnel, product, and environmental protection by exhausting 100% of contaminated air.

Exhaust Interlock

The Nu-430 contains an exhaust interlock system that prevents operation of the internal supply blower unless the exhaust flow is sufficient to provide the correct air barrier inflow velocity at start up.

TouchLink2 Electronic Control System

An easy to use color touch screen operates all system functions.

  • On/off for lights, blower, and interior outlets.
  • Monitors high/low limits for down flow, inflow and sliding window position.
  • Password protection locks out unwanted changes to the system.
  • Date/clock display and timer function can be used as a laboratory timer, to set purge cycles, outlet timer, UV light timer, auto-run timer, NiteCare night set back, or weekend turn-off.
  • Filter status displays remaining filter life
  • Complete diagnostic functions for a NSF trained service technician or certifier.
  • NEW – BACnet RS-485 interface provides the Building Automation System (BAS) a two-way communication link to query the TouchLink2 operating information. View airflow data, alarm status, etc. and control TouchLink2 for facility energy savings by initiating NiteCare (Night Setback System).

IntelliFlow Airflow Control

Assure optimal biological safety cabinet performance by monitoring, displaying, and controlling real time airflow with the same methods of you annual certifier with a dual thermistor airflow sensors powered by measurement instrument company TSI™ controlling downflow and a pressure flow grid controlling exhaust flow.


Night setback system allows for an energy saving sterile working environment when the cabinet is not in use.

Monolithic Pressure Tight Construction

A single shell, high grade stainless steel, fully welded cabinet eliminates potential leaks that may occur through failures of gaskets and cabinet seams.

Energy Saver Motor

NuAire ultra-high efficiency motor technology lowers energy costs while increasing filter life from the NSF minimum requirement of 50% (3 year equivalent life) to 300% or higher (10 or more years).

TruLaminar 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

Strong inflow air velocity of 105 fpm (0.53 m/s) over an aerodynamic airfoil creates maximum personnel protection.

HEPEX™ Zero Leak Airflow System

The HEPEX™ plenum inflates to provide quiet uniform air without transferring vibration. Positive pressure chambers and ducts are surrounded by negative pressure eliminating potential leaks. HEPEX™ fabrics are incredibly durable. They are flameproof, provide a barrier against water, gases, fluid, and dust as well as resist to chemicals, oils, and greases. It even holds antibacterial properties and is impregnable meaning harmful materials become trapped in the filters.
