United Air Specialists recently introduced the SDC series of compact shaker-style dust collectors. These self-contained collectors are designed to effectively capture and filter airborne pollutants in intermittent-duty industrial processes while occupying minimal factory floor space. The SDC is easy to install and arrives with everything necessary to begin collecting dust. The shaker system also provides energy savings by self-cleaning the filter media without using expensive compressed air. Upon shutdown, SDC dust collectors automatically shake the filter media free of dust.
