Description
Safety Systems
The optional stand is may be ordered in two configurations; a manually
adjustable from 750 mm to 950 mm working height, and a fixed 864 mm
working height with attached casters..
A stainless steel one-piece work surface is standard. Optional armrests
ensure a comfortable working position for the user and minimize blockage
of airflow at the front grille.
Internal outlets, provided as the power source for accessories, are provided
standard, a single outlet on each side.
Test hoses (aerosol challenge ports) are located under the work tray.
The supply plenum hose is located on the left and the exhaust plenum hose
on the right.
Note Do not remove the caps of the two test hoses to check for supply and
exhaust airflow.

Negative pressure air system
A negative pressure air system combines with HEPA filters in the supply
and exhaust airflow for personal and product protection.
Personnel protection
Inflow air along the entire working opening at a constant high velocity
prevents leakage from the work opening of the chamber.
Exterior air pressure being higher than the internal air pressure creates
negative pressure, ensuring containment in case of cabinet leakage.
Product protection
Steady airflow within the air system ensures constant downflow, allowing
the HEPA filters to remove contaminants so that the samples are always
surrounded by ultra-pure air. Harmful particles are not carried over the
sample chamber (protection from cross-contamination).
HEPA filters
The downflow air within the chamber and the exhaust air are cleaned by
HEPA filters.
Safety lockout
To protect from UV radiation, the optional UV light will not turn on if
the front window is open. While the UV light is on, the front window is
closed and locked. The closed window blocks out the UV rays. Opening
the window will cause the UV light to turn off.
