MULTIPLEX FILTRATION SYSTEM, SUMMARY
Pre-Filter Main Filter
Electrostatic Protects the main filters from aerosols, mists, dust and particulates with filter efficiency
superior to 95.5% down to 0.5 microns.
Standard --
Activated Carbon FILTCO
™
Sourced. A single carbon filter containing activated carbon granules chemically
formulated to capture one or more specific vapors or family of vapors.
Single:
One type of activated carbon.
-- Specify
Stacked:
Two or more single filters each
with a different type of carbon.
-- Specify
HEPA/ULPA A self-contained filter designed to physically capture particles larger than 0.3 microns (HEPA)
or 0.12 microns (ULPA). When used with a HEPA/ULPA filter the ductless fume hood may be
applied as a Class I Biological Safety Cabinet.
-- Specify
Purair P5-36, shown with
Multiplex Filtration System.
The Purair Basic Series
ductless fume hood
maintains a constant
face velocity of 100 FPM in
compliance with USA and
international standards
for safety and performance.
Contaminated air is pulled
through the Multiplex
filtration system where
activated carbon adsorbs
chemical vapors and/or
particulates if HEPA/ULPA
filters are used. Clean
air is returned
to the room.
A. The main filter is
easy to replace, no tools
required. The filter clamps
tightly against the filter
gasket to prevent filter
bypass and maintain
filter integrity.
