What are typical cost savings over centrifugal blowers?
A cost comparison of controlled air flow air wipes and centrifugal blowers is not a comparison of air consumption, but rather of the electrical consumption needed to produce the end result. Controlled air flow air wipes require only fractional horsepower to generate the air flow needed for successful drying. This requirement is so small that the demand on existing systems is negligible. At the same time, a centrifugal blower requires much more horsepower to function and, over time, will consume a great deal more electricity. A typical centrifugal blower employs 7.5 horsepower which is totally dedicated to the purpose of drying one production line. The electrical power needed to operate such a system over the course of a year (24 hours/day, 6 days/week) is approximately 41,900 kWh. By contrast, a controlled air flow, air wipe, utilizing a two-stage compressor, will require only .84 horsepower to generate the required volume of air. This is based upon a pressure of 80 PSI (5.6 bar). The
