The purity of the air is achieved.
The Maxifilter purification system enables reliable treatment of breathing air and technical gases according to DIN EN 12021¹ when using original filter cartridges. Placed after the last compressor separator and before the pressure maintenance valve, it has the separator after the 2nd and 3rd stage to create a first, fundamental barrier against humidity. The filtering capacity with inlet air at 20 ° C and 200bar is 620 m³.

Electric motor
One of the fundamental parts of the compressor: the motor transfers the motion to the pumping unit through the belt. The 4 to 5 three-phase electric motor is available on this model, 5 kW.

Chassis
Essential and compact, this frame is designed to facilitate portability. The tilting motor-holder plate guarantees the constant tension of the V-belt. The protective casing in thermo-formed material conveys the cooling air on the cylinders and on the inter-stage pipes. This guarantees a high compression efficiency.
