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.

Motor
One of the fundamental parts of the compressor: the motor transfers the motion to the pumping unit through the belt. On this model is available the single-phase or three-phase electric motor from 3 to 5, 5 kW.

Chassis
Essential and compact, this frame is designed to facilitate portability. The tilting motor-holder plate guarantees the constant tension of the V-belt. The protective casing in thermo-formed material conveys the cooling air on the cylinders and on the inter-stage pipes. This guarantees a high compression efficiency.

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.

The details that matter
The compressor features a compact frame with handles for easy transport.

Models of the SMART line are the direct evolution of the STANDARD ones, among the most known and sold in the world. All versions are equipped with two high pressure hose connections (from 232 to 330 bar), a single-phase or three-phase electric motor, robust pumping units and a compact frame with handles, suitable for transport. As Optional we find the external charging panels and the electric panel complete with its automatisms including the automatic condensate drain and the pressure gauge with
autostop.
