UAS has been awarded Patent No. 6,902,592 by the U.S. Patent and Trademark Office for the pulse-jet cleaning system in its SFC Series downward flow cartridge dust collectors. Introduced in 2003, the collectors remove harmful pollutants resulting from both process and nuisance manufacturing processes. The company's pulse jet technology requires fewer pulses to clean the cartridge filters, meaning less compressed air is used. - Cincinnati, Ohio - (513) 419-7062 - www.uasinc.com
