Abstract
A paint spray gun for use in association with a HVLP turbine blower and an attachable paint container divides input air flow into two horizontally adjacent channels. Air flow through one channel remains open whereas air flow through the second channel may be varied by a side air controller such that when air flow is cut off from the second channel, the paint mixture is sprayed in a substantially circular shape whereas when air flows through the second channel the paint mixture is sprayed in a substantially fan shape. In another embodiment, a rotatable nipple is positioned to redirect some air flow from the channels to drive paint from the paint container.
