gauge. The air damper provides a means for operating the glove box at a more negative
pressure when the blower is running at low speed (low air volume). The filtering system
consists of one inlet HEPA and one exhaust HEPA filter (both rated at 99.99% efficient on
0.3 micron particulates). A “roughing” prefilter is also provided to capture room air
particles and extend the life of the inlet HEPA filter.
Optional Filters: (for installation between exhaust HEPA and blower).
Charcoal Filter: (Cat. No. 5065300) contains 4 lbs. of Barnebey and Sutcliffe type 787
impregnated, activated carbon for removal of gaseous radioisotopes.
Additional Exhaust HEPA Filter Kit (Cat. No. 5065200) same as filter shipped with unit,
plus an extended length tube for connection to blower.
