Less, more. 

The best answer to those who want small-sized breathing air compressors, while maintaining high performance. Equipped with four different TPS (Tropical Plus Superdry) pumping units, Ergo TPS is powered by an electric motor. It has a panel with a monitoring system complete with pressure gauges, autostop with adjustable electronic pressure switch, automatic condensate drain and control of the direction of rotation. It is also equipped with two connections for high pressure hoses and an increased filtering system with two Hyperfilters. Optionally, you can add the remote charging panel.

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.
