Filter Clamping Bolt
evenly seals the HEPA filter to the
frame of the enclosure. See Figure 4-1 and 4-2.
12.
Control Panel
. The control panel, which is located above
the sash, contains the filter pressure gauge, control switches
and the electronics. See Figure 4-1.
13.
HEPA (High Efficiency Particulate Air) Filter
is rated to
remove 99.99% of all particles 0.3 micron in size. See
Figure 4-2.
14.
Lamp Ballast (Not Shown)
for the fluorescent lamp is
located behind the control panel.
15.
Variable Digital Timed UV (Ultraviolet) Lamp (Not
Shown)
, allows the operator to surface disinfect the work
area of the enclosure when it is not in use. The UV light
rays will not penetrate the plane of the sash and lower
airfoil. The UV light timer is variable with eight settings in
minutes of 5, 10, 15, 30, 60, 120, 240, and infinity. This
provides extreme flexibility for PCR protocol. It is easily
changed by, selecting the time necessary located on the
control panel. To operate, simply select the UV light
option on the light switch.
16.
UV Sash Closure
provides added safety to prevent access
inside the enclosure. See Figure 4-3.
17.
Accessory Work Surface
is dished and contoured to fit the
dimensions of the enclosures to contain spills.
18.
Upper Diffuser Screen
provides protection for the HEPA
Filter and promotes even distribution of downflow air. See
Figure 4-2.
19.
Prefilter (roughing)
enhances the life of the HEPA filter
by trapping large particles. It should be replaced quarterly.
Safety Precautions
1. Although the enclosure has been engineered to maintain
Class 5 air conditions, caution should always be used while
working. Prior to using the enclosure, check to make
