charging and collecting stages.  This assures that all
system air is filtered.

Conventional media filters rely on fiber density for par-
ticulate removal efficiency.  A media filter is rated effi-
ciency is based on the average efficiency over the fil-
ter is life.  Since the initial filter efficiency is lower than
the rated efficiency, a substantial amount of particles
go unfiltered.  In contrast, PurePac delivers the rated
efficiency instantly and continuously.  The high-densi-
ty charging and collecting zones produce an immedi-
ate and constant removal rate regardless of particle
size. 

The PurePac uses a programmable logic controller
(PLC) for system control and monitoring, in conjunc-
tion with high frequency electronics, to deliver opti-
mum performance and assure the highest degree of
reliability.

The versatile control system can be easily integrated
with existing building management systems, adding
another degree of reliability in the overall building sys-
tem.

The durable, all aluminum 2-stage electronic collec-
tors feature unitary construction and are designed to
last the lifetime of the system.  The integrated auto-
matic wash system assures optimum performance
and maximum system reliability.

PurePac's design features increased collector surface
area in a smaller package compared to conventional
systems, resulting in higher dirt holding capacities and
reduced system footprint.  This translates into extra

available floor space, up to 30% in some instances.

PurePac's low resistance to airflow results in reduced
fan horsepower and fan energy cost.  Over a period of
time, this reduction amounts to significant savings in
energy costs.  Since PurePac uses wash-in-place
electronic collectors, replacement filter cost, disposal
cost and labor cost are eliminated.

When it comes to value, PurePac delivers.  High per-
formance and reliability in a compact design, and low
operating cost make PurePac the ideal choice for
today's IAQ challenges. Call us, and we'll prepare a
life cycle cost comparison for your filtration system
and show you how PurePac can deliver performance,
reliability and value.

PurePac Front Access Model (FA) is packaged as a
complete system, including the electronic air purifier,
system control, detergent dispenser and system
accessories.  Components are furnished factory
assembled, except for the electronic air purifier, which
is shipped knocked-down for field installation inside
the air handler or ventilation duct.

PurePac Model FA uses Flanders type HCC electron-
ic collectors and modular design, arranged in multiple
tiers and varying widths to attain the specified capac-
ities and efficiency.  The versatile design and modular
construction can accommodate all sizes of ventilation
systems by installing multiple units side-by-side.
