1. A spray device comprising:
a first spray tip including a first fluid pathway that defines a first flow area, wherein the first fluid pathway comprises a first swirl chamber having an outer perimeter and flutes having inner ends that direct a first fluid into the outer perimeter of said first swirl chamber for rotating the first fluid in a circular pattern within said first swirl chamber;
a second spray tip including a second fluid pathway that defines a second flow area that is larger than the first flow area of said first spray tip, wherein the second fluid pathway comprises a second swirl chamber having an outer perimeter and flutes having inner ends that direct a second fluid into the outer perimeter of said second swirl chamber for rotating the second fluid in a circular pattern within said second swirl chamber; and
said first and second spray tips being side-by-side and spaced from one another at a distal end of said spray device.
