Coltri Compressors

Coltri Compressors (Aerotecnica Coltri) is one of the world’s most recognizable manufacturers of high-pressure breathing air systems. Founded in the 1960s, the company has spent over 60 years refining the technology behind safe, breathable air. Based in Desenzano del Garda, Italy, Coltri has grown from a small mechanical workshop into a global industrial powerhouse, producing compressors that are synonymous with reliability and Italian engineering excellence.

As a specialist in pneumatic technology, Coltri offers a vast range of compressors, from ultra-portable units to heavy-duty stationary systems. Their “MCH-6” series is particularly noteworthy, widely regarded as the most popular portable breathing air compressor in the world. These compact, lightweight units allow commercial divers and remote expedition teams to fill cylinders on-site, providing autonomy in locations where bulk gas delivery is impossible.

In addition to the portable range, Coltri manufactures powerful stationary compressors like the “Smart” and “Ergo” series, designed for continuous duty in dive centers and industrial facilities. These systems are built around Coltri’s robust pumping units, which feature low-rotation speeds to reduce wear and noise. Whether for filling scuba tanks, SCBA sets for fire departments, or industrial gas storage, Coltri’s rigorous quality control ensures that every litre of air meets the strictest purity standards (DIN 3188 / EN 12021).
