incorporated into the design to improve ergonomics so the operator can use the cabinet properly without
sacrificing comfort or safety.
Motor/ blower capacity
A motor/blower's capacity is measured by its ability to provide a nearly constant volume of air as
resistance increases because of filter loading. Verification by a simulated filter-loading test has
established that the SterilGARD
III cabinet is capable of automatically handling a 50% increase in
pressure drop across the filter without reducing total air delivery more than 10%. With the use of the
manual speed control, a 200% increase in the pressure drop across the filter can be handled. This results
in extended filter life, which relates to significant cost savings over the life of the cabinet.
One-piece interior wall construction
The interior side and rear walls of the work area are constructed from a single piece of 16-gauge
stainless steel. It has 7/16” [11.1mm] radius (rounded) corners to help prevent buildup of contaminants
and aid in cleanup.
Protective screen
Located under the work surface at the bottom rear and sides of the return-air plenums, a protective
screen, integral to the interior walls, is provided to prevent wipes and other paper materials from being
drawn into the blower system. This feature eliminates costly decontamination processes and downtime.
The screen affords easy access to trapped materials and should be kept clean at all times.
All-metal plenums
The plenums are constructed entirely of either carbon steel or stainless steel in order to provide strength,
durability, air-tightness and resistance to deterioration.
Recessed stainless steel work surface
The work surface is constructed of corrosion-resistant 16-gauge type 304 stainless steel, with a satin
finish that diminishes light reflection. It is recessed to retain spills, and the radiused corners make for
easy cleaning and disinfection.
Cabinet exterior panels
External panel construction is of 16-gauge cold-rolled steel, or 16-guage stainless steel protected by a
smooth white baked enamel finish.
Tested HEPA filters
Both the downflow and exhaust filters in the SterilGARD
III Advance
are scan-tested HEPA filters.
They are 99.99% effective on particles of 0.3 micron size. Each filter is scan-tested after installation to
assure that there are no leaks >.01% of upstream concentration.
Viewscreen
The cabinet's ¼” safety plate glass sliding viewscreen may be opened to 18-¼ ” for placement of large
items in the work area, and may be fully closed for system shutdown or UV light operation.
