Kompressor Coltri Ergo / Komba C-315 Full Automatic

Maximum efficiency in motion.

Practical to transport, ERGO stands out for its sturdiness
and great operational efficiency.
Equipped with monitoring panel complete with interstage
pressure gauges, hitchhiking with adjustable pressure
switch, automatic condensate drain and direction of
rotation control.

3-stage high pressure pumping unit.

• Monobloc in aluminum,
• Crankshaft in forged steel
• Splash lubrication
• Forged aluminum connecting rods
• Main roller bearings
• Roller connecting rod bearings
• 1st and 2nd stage cylinders in aluminum with hard nicasil coating
• 2nd and 3rd stage slide guide cylinders in aluminum with hard nicasil coating
• 3rd stage cylinder in special treated steel.
• Stainless steel intake and exhaust valves
• Interstage cooling pipes in stainless steel
• Separator after the 2nd and 3rd stage
• Safety valves after each stage
• Maxifilter purification system
• Oil level sensor

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

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.
