Abstract:

A replaceable baffle for dropping high pressure air to low pressure air for atomization and for pattern shaping in a high volume low pressure (HVLP) air paint spray gun. The baffle has a first plurality of orifices for distributing and dropping the air pressure to a low pressure for atomization and has orifices arranged in two stages for dropping the air pressure to a low pressure for pattern shaping. The baffle may be replaced with a baffle having different sized orifices to permit use of different air cap and/or fluid tip designs on the spray gun when applying paints having different flow properties.
