Installation of HEPA Filters and

Filters
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 and HEPA Filter Bag-
In/Bag-Out Procedure. See Figure 4-2 for HEPA filter location,
HEPA filter gasket, filter clamp bolts, and bag-in/bag-out flange.
The XPert enclosures have a true bag-in/bag-out HEPA filter to
safely dispose of the filter. 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.
