This conventional Devilbiss AGX automatic spray gun is designed for use with industrial robots, reciprocators and stationary mounting. This gun is the predecessor of the AGXV (HVLP technology due to a modified spray head, i.e. different baffle, air cap and partly nozzles/needles). The AGX-550 spray gun comes with a stainless steel tip for use with many waterborne materials and even chlorinated solvents (if used with chlorinated solvents, make sure all other fluid handling components are also compatible). The AGX-552 guns are specially equipped with carboloy fluid tip and needle for use with water-mix materials and abrasives. The AGX-553 guns include a special 300-grade stainless fluid tip with UHMW (Ultra High Molecular Weight) polyethylene insert (needle seat) and 300-grade stainless steel needle for use with mildly abrasive or corrosive materials. The spray head is also detachable for a fast needle packing replacement. A special feature are the PTFE (teflon) needle packings which are spring loaded for extended service life.


General purpose solvent based and waterborne coating materials,including chlorinated solvents.
