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.

A typical 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 stale- ness. 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 contami- nants. A successful ventilation system reduces the levels of contaminants through high efficiency filtration and gas phase control, while at the same time, reduc- ing maintenance, upkeep, and operating costs.

Filtration System Considerations

PurePac's particle collection efficiency is continuous and not highly dependent on particle size or filter load- ing, therefore actual efficiencies of 90-95% and high- er 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 elimi- nate 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 fil- tration system is directly related to the filter is resist- ance. PurePac's low and constant 0.25î w.g. resist- ance results in reduced fan horsepower and a signifi- cant energy savings compared to conventional filtra- tion. Since PurePac's efficiency is instant and contin- uous, fouling of heating and cooling coils is reduced, resulting in higher performance and reduced operat- ing cost of the system.

PurePac incorporates a permanent self-cleaning sys- tem, eliminating the replacement and labor cost of buying, changing, and disposing of filters. A life 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, continuous- ly and reliably.

High reliability, optimum performance, and low operat- ing cost make PurePac the IDEAL SOLUTION for today’s indoor air quality challenges.

Performance

PurePac uses a 2-stage electronic collector for partic- ulate 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
