Baker ChemoSHIELD CS500, Operator'S Manual

Page: 7 / 20

Building exhaust requirement
Your ChemoSHIELD
®
cabinet has an 8” exhaust collar and requires the building exhaust connection to
handle 1.8” WC at 310 CFM.
Chamber walls and tunnel construction
The chamber walls and tunnel of your ChemoSHIELD
®
are constructed of 16 gauge, type 316 stainless
steel. The easy-to-clean 7/16-inch radiused (rounded) corners prevent buildup of contaminants and resist
corrosion. The chambers are designed to be leak tight to 2” WC.
All-metal plenums
The plenums of your ChemoSHIELD
®
unit have been constructed entirely of metal in order to provide
strength, durability, air-tightness and resistance to deterioration.
Stainless steel work surfaces
The work surfaces are constructed of corrosion-resistant 16-gauge, type 316 stainless steel. They have a #4
satin finish that diminishes light reflection.
The work chamber has a three (3) piece flat work surface and the pass-through chamber has a two (2)
piece flat work surface. The work surfaces are removable so that you can access the exhaust filters.
Cabinet exterior panels
External panel construction is of 16-gauge cold-rolled steel protected by a smooth white baked enamel
finish.
Tested HEPA filters
The filters in the ChemoSHIELD
®
are scan-tested HEPA filters. They are 99.99% effective on particles of
0.3 micron in size. Each filter is scan-tested after installation to assure that there are no leaks >.01% of
upstream concentration.
Viewscreens
Your ChemoSHIELD
®
has 3/8-inch shatterproof, clear polycarbonate in both the pass-through door and
the work chamber viewscreen.
Work chamber and pass-through lighting
The lighting system produces at the work surface of the work chamber an average of 50 foot-candles of
illumination and 45 foot-candles at the work surface of the pass-through chamber. Two fluorescent lamps
are externally mounted to minimize heat buildup. The cabinet uses one F39T5/HO fluorescent lamp for the
work chamber and one FT36W-2G11-41 fluorescent lamp for the pass-through chamber.
Chamber base pan construction and clean ability
The base pan is constructed of 16-gauge, type 316 stainless steel with 7/16” radius in all corners to
facilitate cleaning. The work surfaces can be repositioned for cleaning of the chamber pans.
Cabinet air balance adjustments
Only a technician with proper training and equipment should perform air balancing. (See Section IV, "On-
Site Checks and Maintenance Procedures.")
