The tubular frame/handle is actually a .5 liter air tank! The 1/4 hp compressor runs at a higher RPM and has more CFM the the now discontinued Power Jet. The CFM (cubic feet per minute) is 1.4 @ open flow. It will produce 60 psi pressure. It includes an automatic shutoff, two built in cooling fans, pressure regulator w/gauge, an Iwata airbrush hose and a built in spray gun holder.
