Abstract
A foamer nozzle assembly has dual screens of intersecting strands in spaced sets of strands, the strands of one set being offset relative to the strands of the other set for establishing two turbulence zones as the flow direction of spray particles is deflected when passing through the first screen and as the flow direction of the spray particles is further deflected when passing through the second screen. The screens are located in a cylinder of the assembly which may or may not define a turbulence cylinder depending on the spacing of the screens from the discharge orifice. The screens may be spaced apart a given distance to establish a turbulence zone therebetween.
