Abstract (en)
An apparatus for collecting material from a surface wherein the material to be collected is carried by pressurised air in a duct (D), and the duct (D) has an access port (2,3,4) for imparting energy to the stream of pressurised air in the duct (D). This lowers the pressure in the downstream region of the duct (D) and increases the suction in the duct (D). <IMAGE>
