ChemGARD®
and ChemGARD®-RI (Radioisotope) High Performance
Fume Hoods Feature Continuous Flow Bypass for Improved
Performance. |
| Baker
ChemGARD® high performance fume hoods have
been developed by experts in containment technology.
Both ChemGARD® fume hoods employ unique
airflow characteristics within a streamlined, unobstructed
work area to provide uniform, energy-saving operation,
minimizing backdrafts, turbulence and eddy currents. |
ChemGARD®
Model FH5C
|
The
Baker ChemGARD® is the Industry’s Only
Fume Hood Which Carries the UL Classification. |
| Features |
| ChemGARD®
fume hoods are designed for unparalleled safety for
critical laboratory applications.
| |
The
continuous flow bypass design substantially
reduces roll effect, minimizes lingering
concentrations above and behind the viewscreen,
and reduces contaminant concentrations near
the edge of the sash, reducing potential exposure
hazard to personnel. |
| |
Combination
horizontal/vertical sash maintains optimum face
velocity while reducing the amount of exhausted
conditioned air to approximately one-half the
air of conventional cabinets with vertical-only
sashes, resulting in significant energy savings.
|
| |
Angled
side-entrance, airfoil and radius work surface
deliver undisturbed airflow to the work area
with minimal turbulence. |
| |
The
Airwatch II airflow monitor can be custom configured
to meet a variety of laboratory safety requirements.
|
| |
A
mass airflow sensor monitors either face velocity
or exhaust duct velocity, and activates an alarm
if monitored flow drops below safe limits. |
| |
ChemGARD®-RI
includes structural and fabrication enhancements
developed specifically for use with radioisotopes..
|
| |
Select
from three optional base cabinets to suit any
laboratory application. |
| |
All
ChemGARD® electrical and plumbing
services are fully installed and ready for easy
connection for simple, cost effective installation
and maintenance. |
|
| General
Construction Features |
| The
aerodynamic ChemGARD® design employs fixed
air slots at maximum safety configuration to alleviate
the need for cumbersome operator adjustments.
|
ChemGARD®
construction materials are fireproof.
|
|
Top-suspended,
12” wide safety plate glass sash panels are
easily removed for cleaning. |
|
Unique
internal baffle location minimizes retained
vapors in work area. |
|
ChemGARD®
fits through standard doorways and, once installed,
requires only a 2” aisle overhang. |
|
Radius
bottom airfoil minimizes turbulence. |
| |
| ChemGARD®
General Purpose Models |
|
Stainless
steel bolted, 16-gauge, Type 304 stainless steel
liner provides long-term durability, easy cleaning
and resistance to corrosion (can be epoxy coated
as an option). |
|
A
molded, dished epoxy resin work surface confines
spills. |
|
Recessed
work surface encourages proper placement of
potentially hazardous chemicals. |
|
The
continuous flow bypass design substantially reduces
roll effect, minimizes lingering concentrations above
and
behind the upper viewscreen, and virtually eliminates
contaminant concentrations near the edge of the sash,
reducing potential exposure hazard to personnel.
|
| ChemGARD®-RI
Radioisotope Models |
ChemGARD®
has been extensively tested in The Baker Company
AirFlow Management Laboratory for performance assurance.

|
| Airwatch
II Airflow Monitor and Controls for Customized Operation |
The
microprocessor based Airwatch II airflow monitor is
fully programmable, offering a range of features for
safety, convenience and easier integration into the
overall laboratory safety plan.
|
The
Airwatch II airflow monitor activates an audible
alarm if operating conditions deviate from preset
parameters. |
|
The
programmable display can be set for analog and
digital, or analog only readout. |
| |
Airflow
can be measured in feet per minute (FPM) or
cubic feet per minute (CFM). |
| |
The
alarm probe monitors either face velocity or
exhaust duct velocity; the face velocity probe
is located at the front of the cabinet for easy
access and improved accuracy with horizontal
sash positions. |
|
Lock-out
options for alarm setpoints and calibration eliminate
unauthorized disabling of alarm system. |
|
Integrated
controls include flush membrane switches which
are easy to operate and easy to clean. |
|
Independent
light and duplex electrical outlet switches are
included on the main control panel. |
|
Remote
alarm contacts allow integration with existing
laboratory monitoring and safety systems. |
|
| Horizontal/Vertical
Sash Offers Advantages |
The
ChemGARD® incorporates a combination horizontal/vertical
sash designed for energy savings, operator safety and
convenience.
|
Combination
horizontal/vertical sash provides a protective
physical barrier with full vertical access to
the work area when using either horizontal or
vertical configuration. |
|
Full
vertical access allows easy installation of
experimental apparatus. |
|
Top
suspended 12” wide safety plate glass panels
are easily removed for cleaning. |
|
Side
panels are flush with bell mouth inlet for streamlined
airflow; the radiused bottom airfoil minimizes
turbulence. |
|
Sliding
glass panels can be positioned for increased operator
safety. |
|
Ball
bearing, top hung horizontal sash support provides
smoother sash operation. |
|
Hood
face opening is reduced 50% for energy savings.
|
|
| Lighting
and Electrical System |
|
A
sealed, fluorescent light fixture is located above
gasketed safety-plate glass; fluorescent lamps
are replaced from the front. |
|
Solid-state
lamp ballasts reduce heat output and improve
efficiency. |
|
Two
GFI duplex outlets are protected by a single
10-amp self-resetting circuit breaker to protect
personnel and minimize tripping of breakers.
