Exhaust Interlock
The 435 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.

TouchLink Control System
A 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, exhaust flow 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.

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
An ultra high efficiency motor saves on your energy bills while increasing filter life lowering your total cost of ownership.

Experience Ergonomics
NuAire Biological Safety Cabinets provide maximum knee/thigh clearance that improves the users ability to assume a proper posture. The maximum knee/thigh clearance is accomplished by a design improvement that reduced the plenum height beneath the work surface.

An adjustable base stand provides the ability for laboratory personnel to optimize ergonomic conditions improving leg and forearm support.

A heavy duty plastic armrest minimizes cold conduction and provides additional forearm support.

Cool white lighting and a polished edge window reduces glare allowing for greater visibility and better sight lines to the effective work zone area reducing awkward posture resulting in less eye fatigue and/or neck strain.

NuAire Biological Safety Cabinets provide the largest effective work zone area available which helps reduce arm/neck/shoulder strain.

Our ultra high efficiency motor runs quieter with fewer vibrations creating less stress on the body.

Additional accessories such as an adjustable footrest, elbow rests, turntable, and ergonomically designed chair enhances the user’s ergonomic working environment.

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.

Pressure Tight Construction
Constructed of high grade stainless steel, a weld shell cabinet with back panel minimizes the chance for potential leaks while providing access for maintenance or system upgrades.
