CARBON

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.
