instruction manual
 
The compressor can run either using its integrated battery pack, or can be used whilst plugged into the mains. The compressor provides 3 levels of pressure: 2-15psi which equates to between 15-50psi working pressure throught the airbrush. 
 
It is an extremely quiet compressor which provides on-demand air so it only runs when you have the trigger pulled. 
 
The battery lasts aproximately 70 minutes on a full charge, though it is recommended that you don't exceed 20 minutes of continual spraying in order to prevent the compressor from overheating, though it does have an automatic shut-off to reduce this from happening.
 
The airbrush cup is gravity-fed and holds 7cc of fluid, and the nozzle is 0.3mm with adual-action trigger to allow you to control spray-rate and liquid feed individually. 
 
The braided cable has 1/8 inch  internal thread so it is compatible with a wide range of airbrushes.
