A system comprising an air cap configured to mount to a head of a spray device, wherein the air cap comprises a first air passage, a second air passage, a third air passage and a fourth air passage, wherein: the first air passage has a first curved flow path along a first side of a longitudinal axis of the air cap, the first curved flow path curving inwardly toward the longitudinal axis and terminating at a first outlet; the third air passage has a third curved flow path along the first side of the longitudinal axis of the air cap, the third flow path curving inwardly towards the longitudinal axis and terminating at a third outlet; the first outlet and the third outlet are axially offset from one another; the second air passage has a second curved flow path along a second side of the longitudinal axis of the air cap, the second side being opposite the first side and the second curved flow path curving inwardly toward the longitudinal axis and terminating at a second outlet; the fourth air passage has a fourth curved flow path along the second side of the longitudinal axis of the air cap, the fourth flow path curving inwardly towards the longitudinal axis and terminating at a fourth outlet; the second outlet and the fourth outlet are axially offset from one another; the first air passage having the first outlet and the second air passage having the second outlet are symmetrically placed with respect to the longitudinal axis; the third air passage having the third outlet and the fourth air passage having the fourth outlet are symmetrically placed with respect to the longitudinal axis; and the air passages (304, 306, 324, 326) are configured to direct respective air flows (318, 320, 332, 334) toward a spray to shape the spray. the first air passage has a first curved flow path along a first side of a longitudinal axis of the air cap, the first curved flow path curving inwardly toward the longitudinal axis and terminating at a first outlet; the third air passage has a third curved flow path along the first side of the longitudinal axis of the air cap, the third flow path curving inwardly towards the longitudinal axis and terminating at a third outlet; the first outlet and the third outlet are axially offset from one another; the second air passage has a second curved flow path along a second side of the longitudinal axis of the air cap, the second side being opposite the first side and the second curved flow path curving inwardly toward the longitudinal axis and terminating at a second outlet; the fourth air passage has a fourth curved flow path along the second side of the longitudinal axis of the air cap, the fourth flow path curving inwardly towards the longitudinal axis and terminating at a fourth outlet; the second outlet and the fourth outlet are axially offset from one another; the first air passage having the first outlet and the second air passage having the second outlet are symmetrically placed with respect to the longitudinal axis; the third air passage having the third outlet and the fourth air passage having the fourth outlet are symmetrically placed with respect to the longitudinal axis; and the air passages (304, 306, 324, 326) are configured to direct respective air flows (318, 320, 332, 334) toward a spray to shape the spray.
