a splitter divides an air / product mixture flow , delivered thereto in an air - powered distribution line , between a primary and a secondary distribution channel , which may be flow - coupled to a product hopper or a hose flow - coupled to another product hopper or another splitter . the air / product mixture enters the inlet of the splitter along a first flow path and exits a primary outlet , flow - coupled to the primary distribution channel , along a second flow path generally in - line with the first flow path . air / product flow is exhausted by a secondary outlet , which is flow - coupled to the secondary distribution channel , at a sideward flow path relative to the first and second flow paths . the velocity flow vector along which the air / product mixture is exhausted from the secondary outlet is at an angle perpendicular to the velocity flow vector along which the air / product mixture is received by the inlet of the splitter .
