Super, but without making noise

The model Super Silent stands out for its high level of noise reduction. User-friendly, it has a high monitoring capability through control systems that track compressor operations.

Quiet performance in any environment

Super Silent is the ideal compressor for those seeking high performance with minimal noise impact. Designed to work unobtrusively, it is perfect for environments where comfort and quietness make all the difference.

Standard equipment includes: two high-pressure hose connections, interstage pressure gauges, oil level and internal cabin temperature control, rotation detector, electric motor, automatic condensate drain and autostop. Depending on the need, the most suitable pumping unit can be chosen.

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

3-stage high pressure pumping unit

Aluminum monoblock
Spray lubrication with tang immersed in oil
Suction filter: 10 um
Pipes, fittings and nuts made of AISI 316 stainless steel
Intermediate condensate separator after the second stage
High-pressure final condensate separators
Safety valves after each compression stage
High heat-dispersion die-cast aluminum cylinders with nicasil barrel coating
Forged aluminum connecting rods
Forged steel crankshaft
Stainless steel second and third stage valves
Heavy-duty roller bearings
Hardened steel third stage with 5 segments made of special cast iron
Second and third stages with thrust pads to eliminate lateral forces on the pistons
Filter system Maxifilter

Electric motor

One of the basic parts of the compressor: the motor transfers motion to the pumping unit through the belt. On this model, the single-phase or three-phase electric motor is available from 4 to 5 ,5 kW.

Purification system Maxifilter

The purification system Maxifilter enables reliable treatment of breathing air according to DIN EN 12021 when using original filter cartridges. Placed after the compressor 2nd and 3rd stage separator and before the pressure maintenance valve to create a first fundamental barrier against moisture. Filter capacity with inlet air at 20°C and 200 bar is 890 m³.

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 individual stages and also of the final separator during compressor operation
Timer for automatic condensate drainage device.
Integrated no-load startup (automatic discharge each time the unit is turned off).
Condensate collection tank 5 liters, with silencer; capacity about 3 liters, for environmentally friendly disposal of condensate.
Interstage pressure gauges display the operating pressure for individual compression stages. This pressure information allows the tightness of the valves (inlet and outlet) of each stage to be checked and potential sources of failure to be quickly identified.

Frame

Silenced cab chassis made for environments requiring low noise level. Oil level and drain reported externally, control console equipped with inter-stage gauges, internal temperature indicator, presence and wrong phase sequence alarm, oil shortage alarm, and run stop and manual condensate drain controls allow easy operation and maintenance of the compressor. Made of steel with scratch-resistant powder coating in Black RAL 9005 color.

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 Coltri compressors 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.
