<p>Spray apparatus has a hollow wand (34) of extensive length and has mounted therein a static mixing element (48) that extends the length of the wand (34) for connection to a conventional mixhead (30). The mixing element (48) has a spiral shaped that incites turbulence and enhances mixing of the foam forming components passing through the wand (34) form the mixhead (30). A nozzle (50) having a singular central orifice (52) through its tip is mounted on the distal end of the wand (34) and houses a floating core (54). The core (54) has a convex end (56) facing the orifice (52) and has a peripheral surface (60) with angled channels (62) that converges in the direction of the orifice (52) and separates the mixed components into streams directed toward the orifice (52). Together with the orifice (52) this core (54) atomizes the mixed components and causes the discharge thereof in a uniform atomized cone-shaped spray pattern.</p> |
