A spray gun using high volume, low pressure air includes a liquid nozzle with a conical face and a coaxial liquid outlet therein and a housing having an air chamber of greater diameter than a diameter of said liquid nozzle, for providing atomizing air to an air cap, fitted to said air chamber. The air cap has a centered opening therein subtended by a radially expanding frusto-conical surface, for accepting the conical face of said liquid nozzle. Pattern adjusting outlets are provided for directing air in a direction towards the liquid nozzle axis. A distributor, disposed within said air chamber controls and releasably coupled to the air cap, in combination with said air cap, air flow to said pattern adjusting outlets from the air chamber. The distributor is coupled to the air cap, in a manner enabling rotational movement of said air cap to control air flow to said pattern adjusting outlet.
