"Having used an Apollo 700 hvlp unit for many years with outstanding results,I replaced it with an Apollo 1500 3 stage unit. Compressor fine, gun quality average, fan was not equal one side sprayed heavier. i contacted HVLP shop said they would get back to me never did. I ordered replacement needle and spray tip same size as original, when received the needle angle was less and the quality was better than the original. All good now, in hindsight though I would look for a better quality spray gun."
