CDLTRI COMPRESSORS MADE IN fTALY BOOSTER COMPRESSORS High pressure compressors for technical gases in industrial applications.

Aerotecnica Coltri was founded in the 60s to respond to offers support to the diving sector. We structured our workshops this way, to create an Italian production of high pressure compressors for breathable air. We didn't stop there, our commitment to innovation allowed us to expand our offer with products dedicated to technical gases, applying the same quality-oriented vision without compromise. The constant evolution in design and manufacturing has thus become the central element of our identity: more than fifty years of development have allowed us to create machines that now represent...

COMPACT LINE: BOOSTER

Compact is the perfect high pressure booster for the compression of air, nitrogen and technical gases at non-atmospheric intake pressure between 2 and 8 bar. The controls are easily accessible thanks to the ergonomic design, for a professional machine that can meet the needs of its users. The compact design allows installation even in particularly tight spaces. Compact is a series of air-cooled boosters, equipped with automatic condensate draining system, autostop and re-start functions. DRIVEN BY CHARGING RATE WORKING PRESSURE
