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. s
Neg tive pressure ir 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.
S fety 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.

1300 Series A2 1-3Thermo Scientific
Section 1
Description
Digit l Airflow Verific tion (DAVe)
Independent monitoring of inflow and downflow air velocities
guarantees that product and personnel protection remain
uncompromised. Airflow monitoring determines the velocity of the
airflow in the sample chamber as well as the inflow velocity of air
through the exhaust opening. As soon as airflow velocities rise above or
fall below a specified safety value, an audible and a visual alarm is
activated.
Window position monitoring
The position sensors detect the size of the front window opening and
indicate whether the window is open to the specified work position,
closed (energy saving) or in an unsafe intermediate position.
Thermo Perform nce F ctor
The Thermo Performance actor (PER) is a value that indicates the
safety status of the cabinet. This value is calculated from data
determined by HEPA filter loading, airflow status and values captured
during certification. This data is entered into a parameter list of the
control software and interconnected. The result is indicated on the
display by LEDs.
On certification by qualified personnel with a new HEPA filter, the
performance factor of the unit is indicated by green-green LEDs. As the
unit ages with use, the colors change. Red-red is unacceptable and the
unit should not be used. Any questions as to the safety of the unit
should be resolved before use.
Safety Systems
(continued)

The filter system consists of two HEPA filters for downflow (supply) and
exhaust air.
Room air is drawn into the sample chamber through the work position
window opening. The room air is drawn into the negative pressure drain
pan air duct, then
pulled into the air
plenum in the top
portion of the cabinet.
The room air is mixed
with recirculating
HEPA filtered air from
the chamber, and
filtered proportionally
by the downflow and
exhaust filters. The
filtered air is then
supplied as ultra-pure
air into the sample
chamber of the unit,
and exhausted as ultra-
pure air into the room
environment, or into
an external exhaust
system via an exhaust
transition.
Sectional paper catch grids are installed beneath the work tray in the air
duct between the inner and outer back wall of the unit. These grids
prevent large items such as paper towels and tissues from entering the
plenum where they may impair the function of the blowers or the filters.
The grids can be easily removed for cleaning.
