Mini Silent

Scroll Down

Small, quiet and powerful

Series compressors Mini Silent Coltri provide breathable air in total silence without sacrificing high performance. Available with 100 and 125 l/min pumping units, they are the perfect choice for those seeking efficiency and comfort in any operating environment.

Your silent ally

Breathing air compressors Coltri series.
Mini Silent
, equipped with the MCH 6 pumping unit. of 100 l/min and MCH 8 of 125 l/min, are characterized by extreme quietness, achieved without sacrificing performance. The large space offered by the frame allows the use of a filter system with Maxifilter.

These compressors are available with single-phase or three-phase electric motor drive and integrated control panel with hour meter, have automatic condensate drain and autostop as standard. They are equipped with a hose fill port with operating pressure from 232 to 330 bar.

Watch it closely

Simplicity comes as standard

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

And now for all the details

4-stage high pressure pumping unit

Aluminum monoblock machined on horizontal machining center to ensure maximum precision
Spray lubrication with tang immersed in oil
Suction filter: 10 um
Interstage cooling tubes made of AISI 316 stainless steel
Forged aluminum connecting rods
Forged steel crankshaft with hardened rings
Safety valve on the third stage
PED certified final safety valves
Filter system Maxifilter

Electric motor

One of the key parts of the compressor: the motor transfers motion to the pumping unit through the belt. Single-phase or three-phase electric motor is available on this model from 2.2 to 3 kW.

Purification system Maxifilter

The purification system Maxifilter enables reliable treatment of breathing air according to DIN EN 12021 when using original filter cartridges. The filtering capacity with inlet air at 20°C and 200 bar is 890 m³.

Highest air quality is the goal of a compressor Coltri

Air purity and quality are two indispensable features of our compressors. The air you breathe from the compressors Coltri complies with EN 12021:2014 standards: that’s why with them you can work, have fun, practice in absolute safety.

Purification System Maxifilter

The Maxifilter is a high-performance purification system designed for use with high-pressure compressors intended for the production of breathing air. It uses a combined molecular sieve and activated carbon filter cartridge, ensuring effective removal of moisture, oil vapors, and other contaminants.

This system ensures that the compressed air meets the standards required for underwater, industrial and emergency use, offering maximum breathing safety and reliability.
