This is a Capspray/Titan 2 Quart pressure pot that uses the HVLP Turbine's air to pressurize the pot and feed the paint through the fluid hose and to the guns fluid inlet while the turbines air also pressurizes and atomizes the paint at the aircap. So you get a 2 quart remote cup that does not require a separate compressor. Best results with these pot are achieved using at least a 4 stage turbine or higher. This is a nice piece of equipment ready to work. The last pic posted show the ding in the crease at the bottom of the cup. It's barely noticeable.
