It's a new 50 ft boat. There is no generator, but instead a larger than normal alternator running off the 75hp engine. The boat also has a sophisticated Master Master battery charger and inverter system, that I would hate to fry.

Apparently the compressor draws up to 36 amps.

Thanks for the response. Some of this is now starting to make sense.
this is definitly a 12v system that connects to a battery!use thick cables

another consideration is the air supply,which needs to be somewhere where their is no risk of drawing in exhaust fumes!!!!

other wise these units work well to about 8-10meters,some have a reseviour.

Re: Running a dive compressor

Worst case scenario, we type the Italian instructions into Google Translate.

But, no, the suggestion seems to clip the leads onto the battery terminals. 12 V, last time I checked my car (although these ones are obviously big, better made and more impressive.)

Re: Running a dive compressor

Thanks, Atoll

That is a hugely important point.

No point in breathing in diesel fumes or second-hand air.

I recommend getting one of the inline tanks for it. I have found that it is not all that difficult to breath the system down as the only reserve air you have is what is in the air line itself and at only 55psi that isn't a lot of air. But with the reserve tank in breathing it down won't happen. They aren't all tanks I remember one system had something that looked like a heavy plastic bag that did the job. The reserve tank lets you run more than 1 diver as well.

Re: Running a dive compressor

Thanks, Grant and Atoll.

Once it's up and running, we'll see how well it works. In theory one person can breathe at 10m and two at 5-6m.
