SOLUTION for quality indoor air.
General
The Flanders-Precisionaire PurePac Electronic Air
Purification System is designed for reliable, high effi-
ciency air filtration required in today's commercial
building environments. It is available in both side
access housings and front access units, for use with
air handlers and central ventilation systems.
Configuration
PurePac Side Access units are available in sizes
ranging from 3,000 to 30,000 cfm. Housings are 16
gauge galvanealed steel, continuously welded,
primed and painted. Pre and post mist eliminators,
electronic collectors and built-in cleaning system are
factory assembled into the housing. PLC control and
detergent dispenser are supplied as separate compo-
nents.
PurePac is a new generation electronic air purifier,
incorporating highly dependable high frequency elec-
tronics that deliver the specified efficiency instantly
and continuously. The extremely low resistance to air-
flow means less fan horsepower is needed, compared
to conventional media filters, and because the resist-
ance is constant, the system air volume is always
maintained. Permanent aluminum collectors, built-in
automatic cleaning and a low 35 watts per 1,000 cfm
energy usage, result in a substantially lower life cycle
cost, compared to conventional air filtration systems.
PurePac front access units are available in sizes rang-
ing from 12,000 to unlimited cfm. Pre and post mist
eliminators, electronic collector modules, built-in
cleaning system, Unistrut‚ framing, PLC control and
detergent dispenser are furnished as built-up sub-
assemblies
High performance and low operating cost make Pure
Pac an excellent choice for HVAC system

reduced fan horsepower
• Constant resistance to airflow prevents fluctuations in sys-
tem air volume
• Permanent aluminum collector modules never need
replacing

system air is filtered.
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.
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.
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.
System Description
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.
Reliability
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.
Value
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

module tier. Complete, effective washing of all ion-
izing-collector cell surfaces and all appurtenances
shall be provided. Drive motors, used to oscillate
the manifolds, shall be high torque, gear reduced,
totally enclosed fan cooled type, and be perma-
nently lubricated. Drive linkage shall be a rigid,
positively fastened type without tracks or sprock-
ets.

cleaner shall be furnished with built-in high pres-
sure, low volume water/detergent washing system
and programmable logic control for complete auto-
matic operation.
