For cleaner air in health clubs, gymnasiums, arenas and stadiums, Dynamic Air Cleaners are proven winners.
Dynamic Air Cleaners can be found at the UNI-Dome, home of the University Of Northern Iowa basketball and football programs. In a recent IAQ upgrade to reduce the ventilation air into the building, which was constructed in 1976, Cosatini Engineering (Chicago) used the Ashrae 62 IAQ procedure to calculate a reduction of outside air needed in the facility. The original plan was to use 95% cartridge filters with a bank of carbon to meet Standard 62 requirements. Dynamic V-Banks were used in place of the passive cartridge filters in two 125,000 cfm air handlers. By using Dynamic V-Banks instead of the passive filtration system, the horsepower was reduced enough to enable the contractor to reuse the existing lower capacity fans which saved money on the capital investment. Added benefits included the increased life of Dynamic media over the passive cartridge filters and carbon filters, reduced energy costs to power the air handlers, longer maintenance intervals and subsequent lower labor costs, as well as smaller, lighter replacement media that was easier to handle and store.
High Efficiency Air Cleaning – Dynamic Air Cleaners remove dangerous airborne particles that other air cleaning systems miss…including odors, VOCs, smoke, bacteria, allergens, fine dust, molds and pollen…without producing any harmful ozone. When properly applied Dynamic Air Cleaners can have a significant impact on removing odors from outside air as the air comes through the ventilation system.
Lower Operational Costs - Studies show that 92% of the cost of filtration is something other than the media, including energy (fan horsepower to push the air through the filter), labor to change the media and costs of disposal. Dynamic Air Cleaners can have a significant impact on reducing these costs as compared to bag and cartridge filters. Dynamic V-bank air cleaners can last up to 7 times longer than comparable cartridge filters and can cut down the mid-life static pressure by as much as 1.5” which saves significantly on the horsepower required for specific air handler.
Reduced Ventilation Air Costs - The conventional approach to ventilation air, as specified in ASHRAE Ventilation Standard 62, is to introduce fresh, outside air, to dilute contaminants. The amount of outside air depends on the number building occupants. Cleaning the air, rather than diluting it, can save energy…and money. With Dynamic Air Cleaners, outside air requirements can be cut in half…or even to a third - under the guidelines of ASHRAE Standard 62 IAQ Procedures. And Dynamic Air Cleaners have lower static pressures than other high efficiency air cleaners.
The net savings on using Dynamic Air Cleaners can often generate a return on investment of two to four years.
