PurePac
Electronic Air Purification System
PB1900-0604
General
The Flanders-Precisionaire PurePac Electronic Air
Purification System is designed for reliable, high efficiency 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.
PurePac is a new generation electronic air purifier,
incorporating highly dependable high frequency electronics that deliver the specified efficiency instantly
and continuously . The extremely low resistance to airflow means less fan horsepower is needed, compared
to conventional media filters, and because the resistance 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.
High performance and low operating cost make Pure
Pac an excellent choice for HVAC system
filtration.Optional TechSorb High Mass Zero Dust
bonded activated carbon is available for gas
phase/odor control, making PurePac the IDEAL
SOLUTION for quality indoor air.
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 components.
PurePac front access units are available in sizes ranging 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 subassemblies

Today's IAQ Challenges
The effort to increase performance and efficiency of
buildings has resulted in tighter construction and
reduced air infiltration. Airborne particulate and gas
phase contaminants released from paint, carpeting,
wallpaper, insulation, copy machines, and cleaning
agents become trapped in the work environment.
Atypical ventilation system recirculates 80-90% of the
total air volume in the building, and introduces 10-20%
outside (make-up) air to the recirculated air, in order to
dilute the airborne contaminants and reduce staleness. However, make-up air often introduces new
pollutants to the building, such as diesel and gasoline
engine exhaust, mold, pollen, dust, offensive odors
and other common outdoor pollutants.
The key to providing healthy indoor air is reducing the
levels of airborne particulate and gas phase contaminants. A successful ventilation system reduces the
levels of contaminants through high efficiency filtration
and gas phase control, while at the same time, reducing maintenance, upkeep, and operating costs.
Filtration System Considerations
PurePac's particle collection efficiency is continuous
and not highly dependent on particle size or filter loading, therefore actual efficiencies of 90-95% and higher can be achieved at an economical operating cost.
PurePac is available with optional TechSorb HMZD
impregnated bonded carbon panels for gas phase
contaminant and odor control. The rigid panels eliminate air by-pass, channeling and settling, which are
typical with conventional loose granular carbon filters.
The disposable HMZD panels also offer clean, easy,
removal and replacement.
The operating cost to move ventilation air through a filtration system is directly related to the filter is resistance. PurePac's low and constant 0.25î w.g. resistance results in reduced fan horsepower and a significant energy savings compared to conventional filtration. Since PurePac's efficiency is instant and continuous, fouling of heating and cooling coils is reduced,
resulting in higher performance and reduced operating cost of the system.
PurePac incorporates a permanent self-cleaning system, eliminating the replacement and labor cost of
buying, changing, and disposing of filters. Alife cycle
cost analysis almost always shows that PurePac's
performance and reliability can be justified.
Today’s Solution
PurePac is designed to work in conjunction with a
building’s air handling units and ventilation systems,
delivering the specified level of efficiency, continuously and reliably.
High reliability , optimum performance, and low operating cost make PurePac the IDEAL SOLUTION for
today’s indoor air quality challenges.
Performance
PurePac uses a 2-stage electronic collector for particulate control. A high-density, low power first stage
charges each particle. The charged particles then
travel downstream into the second stage where they
are repelled from the air stream, captured, and
retained on collector plates.
The electronic collector uses an airfoil design that
eliminates air-bypass, so all of the HVAC system air
and airborne particulate pass directly through the

Engineered Products: 1-800-637-2803 Replacement Products: 1-800-347-2220
charging and collecting stages. This assures that all
system air is filtered.
Conventional media filters rely on fiber density for particulate removal efficiency. A media filter is rated efficiency is based on the average efficiency over the filter 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-density charging and collecting zones produce an immediate and constant removal rate regardless of particle
size.
Reliability
The PurePac uses a programmable logic controller
(PLC) for system control and monitoring, in conjunction with high frequency electronics, to deliver optimum 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 system.
The durable, all aluminum 2-stage electronic collectors feature unitary construction and are designed to
last the lifetime of the system. The integrated automatic 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
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 performance 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
