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.
Electrical cabinet
- ON / OFF switch with motor protection switch.
- Electromechanical pressure switch that stops the compressor at the final pressure.
- Drainage of all separators between the individual stages and also of the final separator during compressor operation
- Timer for automatic condensate drain.
- Integrated no-load start (automatic drain every time the unit is switched off).
- 5 liter condensate collection tank, with silencer; capacity of about 3 liters, for the ecological disposal of condensate.
- Interstage pressure gauges display the working pressure for the individual compression stages. This pressure information allows you to check the tightness of the valves (inlet and outlet) of each stage and to quickly identify potential sources of failure.
Chassis
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.
