ABSTRACT:
Modular spray gun apparatus and methods are disclosed. In one embodiment, an apparatus includes a handle module and a head module that is removeably coupled to the handle module. The head module includes a first housing having an inlet adapted to be coupled to a source of pressurized gas, a flow passage extending between the inlet and an outlet, and a first coupling member proximate the outlet. Similarly, the head module includes a second housing having a second coupling member removeably coupled to the first coupling member of the first housing, a nozzle fluidly communicating with a spray outlet, and a needle assembly operatively associated with the nozzle to control a flow of liquid material and pressurized gas emanating from a mixing passage through the nozzle.
