Air Filtration – An Energy Conservation Measure

Cleaning Air, Saving Energy, Cutting Maintenance, and Operating Costs

What’s in the air?

<1µm Particulate• Gas Phase: CO2, CO, VOC’s,

etc.• Biological: molds, viruses,

bacteria• Particulate: smoke, dust, man-

made mineral fibers, etc.

Operational Benefits

• Extend media life from months to years.

• Operate at 1/3 the mid-life static pressures of traditional filters.

• 1/3 of the energy use.• Implement ASHRAE 62.1, IAQ

Procedure.• Improved Indoor Air Quality

Economic Analysis

Rapid Return based on:

Reduced energy consumption: • far lower pressure drop and

• the possibility of reduced outdoor air

Reduced media replacement costs: • fewer filters and half the cost

Reduced maintenance costs: • 1/3 or less the number of change outs and less disposal

Case History

• 36,000 cfm

• Replace 95% cartridge and Pre-filters w/V8 modules

• 57,600 kWh/year savings

• 77,876 lbs/year less of C02 emissions

• 10 times the dust holding capacity

Deliverable

• Reduce Fan static by 1 inch mid-life and 1.75 inches dirty

• Avoid larger fan motor• Reduce discharge and radiated sound

levels

• Extend Media life nearly 10 times• Payback in less than 2.2 years

Reviewing Benefits

Dynamic Air Cleaners when properly applied can:

•Significantly reduce sub-micron particles, airborne pathogens and VOC’s (Volatile Organic Compounds – Odors).

•Reduce energy consumption by saving on static pressure vs high efficiency passive filters.

•Lower maintenance costs by saving on media costs and frequency of changing when compared to high efficiency passive filters.

•Potentially lower ventilation air requirements through ASHRAE Std 62 IAQ procedure.

Typical Applications

•Any building using high efficiency passive filter i.e. 65%, 85%,95% and HEPA filters.• Building with a high density of people.• Building using (or considering) the use of carbon

or potassium permanganate filters.• Any building concerned about odors or particulates

in Ambient Air• Clean Room applications – Mfg or Pharmaceuticals.• Manufacturing facility generating a high

concentration of particles, like welding or machine shop smoke.
