Economic Reality
Sales revenues are declining.
Survival by reducing costs is a way of life. Companies are
decreasing staff and delaying capital equipment purchases. The
result? Greater burdens on facility managers, who still need to
keep their building systems running at peak efficiency. As
expenses are scrutinized, HVACR systems represent a significant
percentage of capital costs and operating expenses. Large
energy-using systems, such as chillers and cooling towers, can
translate into significant annual savings or losses depending on
how well they are maintained. Ultimately, HVACR systems
generate an estimated 25 percent of the total energy use in
commercial and institutional buildings and play a critical roll in
keeping occupants comfortable and productive and production
processes efficient.
In addition to economic cuts, facility managers are challenged by increased "green" building trends including energy conservation incentives, Leadership in Energy and Environmental Design (LEED) programs, and corporate environmental goals. Federal energy regulations mandate reducing the amount of carbon dioxide ("carbon footprint") and greenhouse gases generated by power plants. The electricity needed to run HVACR systems is generated by the fossil fuel being burned by power plants. For every kWh used, more greenhouse gas emissions are generated. Dirty, clogged coils and other poorly maintained system components have a direct link to the efficiency of cooling equipment and, consequently, greenhouse gas emissions.
A simple way to help achieve both objectives is
encouraging preventative maintenance products, like air intake
filters, as a way to reduce energy consumption. With EPA
research showing that as little as 0.042 inches of dirt on an air
conditioning coil can reduce its efficiency by 21%, the
installation of an air intake filter is a smart business decision
for energy efficiency reasons alone. Escalating energy use by
a dirty, airflow blocked system can be invisible because energy
bill increases occur slowly over time. For each 1
degree Celsius rise in discharge temp there is an increase in power
consumption of 1.75% and a decrease in cooling capacity of
1.1%. A dirty system runs 80% of the time fighting dirt
when it should be 
operating at 30% during mild weather. The
additional costs associated with labor intensive chemical cleaning
and scrubbing, potential breakdowns and replacement costs of burned
out motors or compressors simply exacerbate an already expensive
set of problems.
Permatron's PreVent® Equipment Protection Filters are air intake filters designed to stop airborne debris at the point of entry, allowing an air handling system to perform optimally. Every filter is custom made to fit the air intake opening, with a variety of design features like flexible vinyl edging or rigid steel frames which allow the filter to be attached easily and securely. Independent testing (done by UL Laboratories) shows PreVent®, with it's low 0.02 in. w.g. initial resistance to air flow, had little impact on system pressure drop. During testing, the filter caused less than 1% change in compressor discharge pressure.
The bottom line is that business operations disrupted by equipment malfunction or failure means a loss of revenue, a reduction in work productivity, loss of customer satisfaction and potential loyalty. You can keep equipment running clean and green between required maintenance with the help of air intake filtration. PreVent® the damage before it's too late!
