3 litre air tank provides a reservoir of air to draw from 
Ensures a regulared air pressure to work with - rather than an average air pressure of the piston cylinder 
Physical motion of piston causes tiny pulsations in the air supply, these are eliminated due to drawing air pressure from the tank
Extended life of compressor as motor is not working constantly 
Air tank acts as efficient first line moisture trap
Auto shut of when tank full
Pressure release valve ensures pressure does not build up
Auto start/auto stop function
Air pressure gauge, adjustable pressure
Air filter and moisture trap
piston type - oil free 
low noise - 47 db
2 air brush holders included 
Power 1/6 HP 
auto start 3 bar (43 psi)
Auto stop 4 bar (57 psi)
