Section 1 Description
The Thermo Scientific 1500 Series A2 offers innovative SmartFlow™ Plus
technology; an automatic airflow compensation system that adjusts motor
speed as filters load, without the use of a manual damper. The
SmartFlow™ Plus system ensures safe working conditions, even between
annual certifications.
The plenum assembly consists of a plenum for the downflow blower and a
plenum for the exhaust air blower. Each blower includes a filter. The
exhaust air is discharged through an opening in the top of the cabinet.
Chamber lighting includes one LED bulb for 4 foot models and two for 6
foot models.
The factory-installed UV light is installed in the ceiling at the front of the
sample chamber. For 6 foot model there are two UV lights installed.

Safety Systems
Three service valve access ports are located on each side panel. When
installing service valves, remove the center of the port plugs at the
perforations.
The optional stand may be ordered in two configurations; a manually
adjustable from 30” to 38” working height, and a fixed 34” working
height with attached casters.
A stainless steel one-piece work surface is standard. 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 in the following configuration:
1584，1589，1574，1579: two single right and left 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
Negative pressure air system
A negative pressure air system combines with HEPA filters in the
supply and exhaust airflow for personnel 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.

Description
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
should remain closed. The closed window blocks out the UV rays.
Opening the window will cause the UV light to turn off.
Digital Airflow Verification (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.
