HEPA Filters
HEPA filters are shipped installed with the gasket on the
downstream side. The HEPA filters are leak checked at Labconco.
A second leak check is recommended before using the enclosure
and at least annually thereafter. Consult your Safety Officer and
Chapter 6 for the HEPA Filter Leak Test. See Figure 4-2 for
HEPA filter location, HEPA filter gasket, and filter clamp bolts.
The Purifier enclosures require decontamination of biohazardous
materials or are used with nonbiohazardous materials or nuisance
powders. All seams upstream of the HEPA filter are jacketed by
negative pressure. This intrinsically safe design ensures
containment.
Carbon Filters (Accessory for Odor Control only)
For carbon filter installation, first remove the upper perforated
cover, secured by Phillips head screws, on the top of the enclosure.
See Figures 4-1 and 4-2 for location of the upper perforated cover.
See Chapter 7 for a list of available carbon filters. All carbon
filters are simply gravity installed with the gasket side down and
down stream on the exhaust side of the HEPA filter. Install the
correct carbon filter for the application.
