The Evolution is really special and a successful piece among the airbrushes. It has a solid system construction, excellent finish and a smooth double-action function which makes the device since its introduction to one of the most widely used airbrushes. The Evolution is with a flow system or in the variant Evolution X with a suction feed system in each case as solo and Two in One model available. The Two in One models contain two nozzle sets in different sizes, providing fast and flexible conversion of the unit for all applications. Like all Harder & Steenbeck airbrushes the Evolution is also equipped with solvent- resistant PTFE seals.
