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

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.
