AirClean
Systems, a manufacturer of ductless fume hoods and chemical
workstations based in Raleigh, N.C., has published
independently-verified results of SEFA 9-2010 “Filter Efficiency and
Adsorption Capacity” testing on Silconazyne bonded carbon filtration.
Silconazyne is a next-generation enhanced filtration media available
exclusively in the Independence ductless fume hood. Testing was
performed in accordance with subsection 4.3.1 of SEFA 9-2010, and
verified by Exposure Control Technologies, a national leader in fume
hood testing and laboratory safety consulting.
Chemicals
representing four key chemical families–inorganic acids, amines,
alcohols and hydrocarbons–are used in the SEFA 9 test protocol. These
are hydrochloric acid, diethylamine, isopropyl alcohol, and toluene. A
separate as-manufactured Silconazyne filter was challenged with each
chemical until filter breakthrough reached the chemical’s TLV. SEFA 9 is
meant to provide ductless fume hood users with an objective baseline
for comparing available filtration technologies.
