Coltri Compressors
Coltri Compressors was founded in the 1960s to respond to requests for support in the diving world. This is how we structured our workshops to create a production of high pressure Made in Italy compressors for breathing air.
We have created them in Italy, where we directly control all processes, from idea to assembly. Our propensity for innovation has allowed us not to stop at diving. We have expanded the offer with products dedicated to technical gases and other fields of application, using the same vision quality-oriented without compromise, typical of Made in Italy.
Portable Lines
Portable Breathing Air Compressors
Refill your cylinders with mini air compressors from the Portables line, even on board. Lightweight and practical, these compressors have written history in the Coltri world, boasting excellent portability to follow you anywhere.
Efficient Line
Air compressors up to 315 liters per minute
The Efficient line features quiet, high-performance air compressors. Strong and “easy” in operation, they are the first choice for those who are already professionals. Products in the Efficient line also impress in flow rate: from 100 to 315 liters per minute.
Prime Line
Portable Breathing Air Compressors
Prime line compressors are high-pressure air compressors with condensate separator and dryer (optional feature on Super Silent TPS model) for tropical climates.
Heavy Duty line
High-performance air compressors
Air compressors in the Heavy Duty line surprise with their high performance: powerful and tireless, they minimize charging speed.
