Medium-Pressure (CM / CB / BM)

Nardi’s Medium-Pressure Series covers three industrial compressor families: CM, CB, and BM. All are built for applications requiring reliable air or inert-gas delivery between 10 and 80 bar (145–1,160 psi).  

CM Series 

CM models are available in 40 bar (580 psi), 60 bar (870 psi), and 80 bar (1,160 psi) versions. They are engineered for demanding industrial duty, featuring rugged construction, adjustable maximum working pressure, and integrated control systems suitable for continuous medium-pressure air or gas processes.

CB Series 

CB compressors are built for very low inlet pressures—typically 50–600 mbar (0.72–8.7 psi)—and deliver output options at 40 bar (580 psi), 60 bar (870 psi), and 80 bar (1,160 psi). Their two-stage, three-cylinder configuration and multiple frame formats (compact or silenced) make them ideal when gas must be taken from a low-pressure source and brought up to a stable working medium pressure.

BM Series 

BM units accept pre-compressed inlet gas in the 4–12 bar (58–174 psi) range and boost it up to 60 bar (870 psi) depending on the model. They deliver high flow rates across a wide performance window and are suited for installations that need to elevate an existing air or inert-gas network for storage, process equipment, or distribution lines.

Together, the CM, CB, and BM compressors form Nardi’s Italian-built medium-pressure platform—flexible, durable solutions for test benches, gas recovery, automation, and industrial processes requiring dependable, mid-range pressure performance.
