The 3-/4stage construction and the heavy duty industrial roller bearings guarantee maximum lifetime for all professional applications. The first stage and the high pressure final stage are equipped with high tech polymer piston rings, which proved their outstanding wear and tear properties during several endurance tests in an independent Quality Inspection Center. The maintenance-free rigid oil pump guarantees reliable lubrication. Resistent A newly developed, supra-light aluminium chassis guarantees best protection against corrosion! Inter- and after coolers made of stainless steel resist toughest climatical conditions. The vibration reducing construction of the motor rocker stands for smoothest compressor operation as well as self-restretching of the v-belt.
