No compromise. 

Ideal for intensive use in hot, poorly ventilated environments or in tropical countries. Designed with an improved cooling system and a filtering system with two Hyperfilters, these compressors are powered by an electric motor and equipped with four different pumping units, all in the TPS (Tropical Plus Superdry) version. They are available with function monitoring systems and electrical panel for automatic compressor shutdown.

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.
