The purity of the air is achieved.
The Maxifilter purification system enables reliable treatment of breathing air according to DIN EN 12021 when using original filter cartridges. Placed after the separator of the 2nd and 3rd compressor stages and before the pressure maintenance valve to create a first fundamental moisture barrier. The filtering capacity with inlet air at 20 ° C and 200 bar is 620m³.
Motor
One of the fundamental parts of the compressor: the motor transfers the motion to the pumping unit through the belt. On this model is available the single-phase or three-phase electric motor from 3 to 5, 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.
The details that matter
The compressor features a compact frame with handles for easy transport.
