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.

	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 minimum 200 lbs/sq.ft., total work surface weight of 1,000 lbs.
	Stainless steel provides long-term durability, easy cleaning and resistance to corrosion.

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.
	ChemGARD^® is the industry’s only fume hood which carries the UL Classification for electrical and personal protection.

Utilities

	Color-coded service fixtures for air, gas, vacuum, cold or DI water and steam, include convenient remote control valves.
	The cabinet includes one fixture and one petcock standard, plus seven plugged penetrations for additional optional fixtures.
	Pre-studded exhaust outlet, 10” diameter, accepts flanged exhaust connection.
	Airwatch II airflow monitor.
