INTRODUCTION
Air Science DWSTM Downflow
Workstations are high efficiency
ductless fume hoods designed
to protect the user and the
environment from hazardous vapors
generated on the work surface.
Unrestricted front and side access
facilitates applications requiring
complex and intensive operator
involvement, while downward airflow
in the chamber protects the operator.
The DWS Downflow Workstation
product line is based on an innovative
Air Science Multiplex™ Filtration
Technology that creates a safe work
environment over the widest range
of applications in the industry.
DUCTLESS
TECHNOLOGY:
The Eco-friendly
Choice
Advanced carbon
filtration technology
offers a safe, high performance alternative
to conventional ducted
fume hood products
for a broad range of
applications.
• Environmental
Benefits. Air Science
ductless fume hoods
isolate and trap
chemical vapors to
prevent ecological
impact through
release into the
environment.
• Versatile. Each
filtration system is
selected for its
specific application.
The Multiplex Filter
broadens the range
of applications.
Carbon filters are
available in more
than 14 configurations
for use with vapors
or organic solvents,
acids, mercury and
formaldehyde. HEPA/
ULPA filters can add
to biological safety.
• Easy to Install. The
ductless fume hood
is self-contained
and does not require
venting to the
out-side. Many units
are portable and
may be moved from
one location to the
next with minimal
down-time and without
filter changes. Set-up,
operation and filter
maintenance are
straightforward.
• Energy Efficient.
Because filtered air is
returned to the room,
no demands are
required of the facility
HVAC capacity for
make-up air.
• Cost Effective. Facility
ductwork, HVAC and
construction costs
are eliminated.
• Safe to Use.
Workstation airflow
and face velocity
protect users from
incidental exposures
to fumes.
• Self testing. Electronic
airflow monitoring
assures continuous
safety. An optional
electronic gas sensor
monitors carbon filter
performance.
Made in
the U.S.A.
This Product Exceeds OSHA, ANSI and Other International Standards.

Ductless Downflow Workstations
PRODUCT FEATURES:
A. Filter I.D. Window: A strategically placed front cover
window shows the installed filter part number and installation date for convenience and to encourage timely filter
replacement.
B. Control Panel: Electronic controls and displays include
switches for the blower, low airflow alarm and electronic
hour counter.
C. Steel Support Frame: The chemical resistant epoxy
coated steel frame adds mechanical strength. Optional
all polypropylene construction is available if desired; see
accessories.
D. Electrostatic Pre-Filter: The 99.5% effective
electrostatic pre-filter can be changed from below the
work sur face while unit is operating, to prevent user exposure
to chemical vapors and powders trapped in the filter.
E. Color: The cabinet is white with blue trim; optional side
panels and front sash are clear. (Black color also available,
see Options and Accessories.)
F. Airflow Alarm: A continuous air velocity monitoring
system alerts the operator upon unacceptable values.
G. Internal Manual Speed Controller: Authorized
personnel may set the centrifugal fan motor speed as
desired.
H. Stand: Optional mobile cart with locking casters.
I. Work Surface: Under the perforated stainless steel
internal work sur face is a polypropylene tray to retain any
spillage.
J. Filter Door Key: Filter access keys prevent unauthorized
removal or accidental exposure to dirty filters.
K. Integral Lighting: A vapor proof fluorescent lamp
illuminates the interior of the workstation.
OTHER FEATURES:
Side Panels and Front Sash: (Optional) When installed,
optional side panels and optional front sash provide better
containment of hazardous vapors. The Front Sash is easy
to open and close.
270 Degree Visibility: Unrestricted user access to the front
and sides of the workstation also admits ambient illumination and provides an unobstructed view of its contents.
Standards Compliant: Performance specifications and
construction meet or exceed OSHA, ANSI and relevant
international standards to assure operator safety.
Construction: All models are available in either metal or
polypropylene construction. See selection chart for specifications and dimensions. Specify metal or polypropylene
when ordering. Available in 110V, 60Hz or 220V, 50Hz models.
