Nardi Compressori
Marine Breathing Air
Air for underwater hull work, maintenance and marine operations.
Nardi builds a complete breathing air platform for marine work. Hookah systems feed air from the surface through a hose, portable compressors fill cylinders where the work is, and stationary compressors, fill stations and air quality monitoring complete a permanent fill room.
Every unit is built to order in Italy.
