emfab – preferred filters for diesel
exhaust and stack emission testing
pure borosilicate glass microfibers reinforced
with woven glass cloth and bonded with ptfe
• withstands folding for weighing and transport.
• every filter flushed with di water to remove
water-soluble residue.
• low moisture pickup eliminates lengthy
desiccations.
• low air resistance.
fiberfilm – economical filters
for air monitoring applications
pure borosilicate glass fibers with
fluorocarbon coating
• unique combination of heat-resistant borosilicate
glass fibers and moisture-resistant fluorocarbon
(tetrafluoroethylene, tfe) coating.
• moisture variations in air or gases during air
sampling will not cause chemical reactions
on the filter.
• low moisture pickup eliminates lengthy
desiccations.
• low air resistance.
applications
• emfab filters – low air resistance for use in critical
aerosol sampling tests that demand filter purity and
non-hygroscopic properties such as diesel exhaust,
stack emission control, and ambient air monitoring for
particulate concentration.
• fiberfilm filters – suitable for high temperature and
hot gas air monitoring applications. heat-treated (ht)
version available for reduction of trace organics.
• tissuquartz filters – high temperature use for analysis
of acidic gases and stack sampling aerosols. ultra-pure
soft water processing reduces residual ion content.
