protective screen is provided to help prevent
wipes and other paper materials from being
drawn into the blower system. This precaution
eliminates costly decontamination and downtime.

and should be kept clean at all times.
All-metal plenums
The plenums of your SterilGARD"II unit have
been constructed entirely of metal 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. Its
satin finish diminishes light reflection. It is
recessed to retain spills, and the 3/16" radiused
con1ers make for easy cleaning.
Cabinet exterior
Extemal construction is of 14-gauge cold-rolled
steel, protected by a smooth white baked enamel
finish.
Tested HEPA!ULPA filters
Supply and exhaust filters in SterilGARDeii are
zero-probed HEPA. They have been found to be
99.99% effective on particles of 0.3 micron size. In
the SterilGARD''II ULTRA 4-foot model only,
supply and exhaust ULPA filters are used, whicll
are 99.999'Yo effective on particulates of 0.12
micron. Eacll filter is scan-tested to assure leak-
free installation.

sliding viewscreen may be opened to 18 Yz" for
placement of large items in the work area, and
may be fully closed for system shutdown.

Work area lighting
SterilGARD"'II's lighting system produces 100 to
150 foot candles of illumination at the work
surface area. The fluorescent tight is extemall.y
m01mted to minimize heat buildup. The unit uses
two common fluorescent bulbs.
Air balance adjustments
Air balancing can be done by either of the
following methods. It should, however, be done
only by a teclmician with proper training and
equipment. (See Section 4, "On-Site Checks and
Maintenance Procedures.")
•
A speed controller adjusts for voltage
differences and filter loading.
•
An adjustable damper compensates for
differences
of supply and exhaust filters if
they are changed at a later date.
Easy filter access
For convenience
and ease of service, the supply
and exhaust filters are loaded and removed from
the front of the cabinet without entry into
SterilGARD'''Il's work area. This is particularly
helpful if the cabinet is connected to an exhaust
duct. Filters should be replaced by qualified
technicians on!
