The SPECO CPS conveying compactor from Enviro-Care can transport debris captured by screens and, in the process, achieve additional dryness, reducing the volume by 40 percent. The screened debris is conveyed through a transport tube by a shaftless spiral. The transport tube is lined with a perforated nonstick polymer that acts as a drainage screen. The outlet plug retention diaphragm is made from the same SINT polymer, but is available in various degrees of stiffness. 815-636-8306; www.enviro-care.com; Booth 5339.
