Product Overview Flat Jet Nozzles Model 47011 Air Edger Flat Jet is an extremely efficient flat jet air nozzle designed to provide a powerful stream of high velocity laminar flow and high force for blow off and cooling where air knives may not be enough. Available in cast zinc and 316L stainless steel for high temperature and highly corrosive environments. When bench tested against several other flat jets, even those with special designed holes or shims, the Air Edger Flat Jet outperformed them all despite whatever claims others may make. Air consumption and noise levels are minimized with its special design and configuration. The Nex Flow Air Edger Flat Jet is available with various size gaps all set by a flat shim. Three standard shim sizes are available .004 (.10 mm), .008 (.2mm) and .020 (.51 mm). One, two or more shims can be stacked for a larger gap and greater force.
