ChemGARD
ChemGARD fume hoods are designed for unparalleled
safety for critical laboratory applications.
• Substantially reduces roll effect (fluctuations in the airflow that may
cause harm to the worker).
• Offers a streamlined, unobstructed work area.
• Minimizes lingering concentrations above and behind the
viewscreen.
• Reduces contaminant concentrations near the edge of the sash
(window), reducing potential exposure hazard to personnel.
ChemGARD Fume Hoods

PAGE 1
1. Combination horizontal/vertical sash enhances both operator safety and energy savings.
2. Sight-tight continuous bypass duct minimizes contaminant concentrations near the edge of the sash, reducing
potential exposure hazard to personnel.
3. Airwatch II airow monitor provides for customized alarm/monitor congurations.
4. Angled entrance, airfoil and radius work surface for undisturbed airow into work area.
5. Color-coded service xtures with convenient remote control valves, positioned outside the air stream.
6. Counterbalanced vertical sash for smooth, single-handed operation.
7. Recessed work surface connes spills.
8. All stainless steel construction for durability and easy cleaning.
9. Optional general purpose, solvent, or acid base cabinet provides storage area.
ChemGARD Design Features

Industry-Leading Technologies Provide Superior
Protection and Maximum Eciency
The aerodynamic ChemGARD® design employs xed air slots
at maximum safety conguration to alleviate the need for
cumbersome operator adjustments.
•
ChemGARD® construction materials are ame resistant.
• Top-suspended, 12" wide safety plate glass sash panels
are easily removed for cleaning.
•
Unique internal bae location minimizes retained
vapors in work area.
•
ChemGARD® ts 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 connes spills.
• Recessed work surface encourages proper placement of potentially hazardous chemicals.
ChemGARD RI Radioisotope Models
• Formed radii, precision-engineered, 16-gauge, Type 304 stainless steel, coved corners, water-tight welded
and polished seams.
• Coved corner stainless steel work surface, ¾" deep, continuously welded to interior.
• Reinforced work surface accommodates lead shielding, supports maximum 200 lbs/sq.ft., to work surface
weight of 1,000 lbs.
• Stainless steel provides long-term durability, easy cleaning and resistance to corrosion.

Airwatch II Airow Monitor and Controls for
Customized Operation
The microprocessor-based Airwatch II airow monitor
is fully programmable, oering a range of features for
safety, convenience and easier integration into the overall
laboratory safety plan.
• The Airwatch II airow 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.
• Airow 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 set points and calibration
eliminate unauthorized disabling of alarm system.
• Integrated controls include ush membrane switches that 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 systems.
Horizontal/Vertical Sash Oers 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 conguration.
• Full vertical access allows easy installation of experimental apparatus.
• Top suspended 12" wide safety plate glass panels are easily removed for cleaning.
• Sidepanelsare ushwithbellmouth inlet forstreamlinedairow; theradiusedbottomairfoil 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, uorescent light xture is located above gasketed safety-plate glass; uorescent lamps are replaced from
the front.
• Solid-state lamp ballasts reduce heat output and improve eciency.
• Two GFCI duplex outlets are protected by a single 10-amp self resetting circuit breaker to protect personnel and
minimize tripping of breakers.
Utilities
• Color-coded service xtures for air, gas, vacuum, cold or DI water and steam, include convenient remote control
valves.
• The cabinet includes one xture and one petcock standard, plus seven plugged penetrations for additional
optional xtures.
• Pre-studded exhaust outlet, 10" diameter, accepts anged exhaust connection.
• Airwatch II airow monitor.
General Purpose Base Cabinet
The general purpose base cabinet has removable front and side panels, plus a 10" deep chase at the rear to allow room
for services. Other features include:
Acid Storage Base Cabinet
The acid storage base cabinet has an acid-resistant polypropylene drip tray, shelf liner and (optional) vent assembly
with exible polypropylene hose designed to“T”into the fume hood exhaust plenum.
• Reinforced shelf, adjustable on 1" centers.
• Dual panel doors, 1 ½" thick, secured with 3" wide continuous hinge, 3-point latch.

• 16-gauge, cold-rolled steel side panels.
• Epoxy powder coated throughout.
• 2" diameter plugged penetrations in back wall, and removable side and rear panels with a 10" deep chase at the
rear to allow for installation of the optional vent package.
• The vent package oers from 10 to 15 air changes per hour, depending on cabinet size.
• Reinforced steel shelf, adjustable on 1" centers.
• Dual panel doors, 1½" thick, secured with 3" wide continuous hinge, 3-point latch.

panels to form a unitized inner cabinet.
• The 18-gauge stainless steel bottom pan is recessed 2" and welded liquid tight.
• 2" diameter plugged penetrations in back wall, and two front removable rear panels provide access to the 10"deep
chase at the rear to allow for installation of the (optional) vent package.
• Access panels are located at each end of the chase.
• An optional vent package oers from 10 to 15 air changes per hour, depending on cabinet size; the vent assembly
with exible hose is designed to“T”into the fume hood
• A reinforced Type 304 stainless steel shelf is adjustable on 1”centers.
• Dual panel doors, 1½" thick, with 3" wide continuous hinge, and secured with a 3-point latch; optional louver doors
are available.
