Purification system

The Maxifilter purification system enables reliable treatment of the breathing air 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 200 bar is 620m³.


One of the fundamental parts of the compressor: the motor transfers the motion to the pumping unit through the belt. The powerful 6.6 kW Honda GX 270 petrol engine is available on this model. or the 7.5 kW Kohler KD15-440 diesel engine.


Open frame designed to facilitate maintenance operations and portability. The tilting motor-holder plate ensures constant V-belt tension. The protective casing in thermo-formed material conveys the cooling air on the cylinders and on the inter-stage pipes, guaranteeing a high compression efficiency. The control console equipped with inter-stage pressure gauges, the internal temperature indicator, the alarm presence and incorrect phase sequence, the oil lack alarm and the start stop and manual condensate drain commands allow easy management and maintenance of the compressor .

Simplicity comes standard.

Imagine having a compressor capable of great performance and endowed with extraordinary solidity. What would all this be without absolute simplicity in managing it?
We believe that innovation is for this: to make everything simpler.

The highest air quality is the goal of a Coltri compressor.

Air purity and quality are two essential characteristics of our compressors. The air you breathe from Coltri compressors complies with the EN 12021: 2014 standards: this is why you can work, have fun and exercise with them in absolute safety.
