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.
