Apollo Sprayers conversion spray guns enable the craftsman to get equal power and flawless performance from either a compressor or a turbine. A brilliantly engineered conversion chamber is machined into the head of the gun to convert high-pressure air into TrueHVLP air. Use the coating of your choice with very little overspray (80-90% transfer efficiency), at the same time achieving a high quality finish that matches your craftsmanship. Enjoy low overspray and a flawless finish.
