Through our partner company Filtco Filters, Air Science is a single source supplier of all pre-filters, carbon
filters, and HEPA/ULPA filters used in our products and those of many other manufacturers.
Filter disposal services are available in
selected markets providing responsible
destruction or recycling of used
saturated filters in authorized facilities.
FILTRATION
At the heart of the Purair product line is innovative
filtration technology. The Multiplex Filtration
System consists of a pre-filter and main filter. The
mechanical design enhances safety, convenience,
and overall value.
• The disposable pre-filter is accessible from
the exterior top of the cabinet.
• A filter clamping mechanism allows for the
filter to be easily installed and ensures an
even seal at the filter peripheral face at all
times to prevent bypass leakage.
• The filter chamber prevents contaminated
air from contacting internal cabinet
mechanisms.
AIRFLOW
Room air enters from the top of the cabinet through the disposable
pre-filter where larger particles are trapped, increasing the service life
of the main HEPA filter.
Air is forced evenly across the HEPA filter to deliver a flow of pure,
uniform air within the work zone to dilute and flush airborne contami-
nants from the work area. A nominal filter face velocity of up to 0.45
m/s (90 fpm) ensures that there is a sufficient number of air changes
within the work zone to eliminate cross contamination and to maintain
optimum cleanliness.
Purified air travels across the work zone to the work surface in a
vertical, unidirectional downflow stream, and then exits the work
zone across the open cabinet front.
FILTER CONFIGURATION
P. The pre-filter may be replaced while unit is in operation.
H. The main filter is easy to replace; no tools required. The filter
clamps tightly against the filter gasket to prevent filter bypass and to
maintain filter integrity.
