Dive compressor for a 85' motoryacht

[Biko]

Does anyone have a recommendation for a dive compressor?

Electric, gas or diesel? For the last two, how have you dealt with exhaust?

After thinking about this, has anyone heard of installations using a hydraulic compressor, driven from the engines or generator? That would seem to offer the best of higher CFM than electric compressors, potentially smaller size since there is only the compressor and no motor, and the exhaust problem is dealt with existing systems.

Any other considerations for a compressor located on a boat?

Some of this has been actually been discussed before. Here are a couple of links.

Hydraulic compressors have been discussed and it is possible for sure. there are a few other threads on this topic, but these are the ones I turned up on my relatively quick search.

A hydraulic compressor will require a pump, reservoir and hydraulic motor. Hydraulic compressors were/are used on aircraft because of existing installed system.

The issue is not the size of the boat but the size of the requirement. Craig has professional connections in this area and could advise. Clark Yacht or Brownie's could assist depending on location.

Thanks for the replies. I have hydraulic power take-off on my engines and could also have on my generators. It wouldn't be difficult to add a compressor as a load, but perhaps take some effort to engineer correctly. I don't have a big requirement and it may very well be overkill so a small electric Brownie may in the end, the best solution.

I had one customer do a very cool set up on his diesel by hooking his generator and the compressor to an electric clutch mechanism. I don't pretend to understand boat engines or clutches, but he can either be powering his battery bank or pumping air with the flip of a switch. He got the idea from watermaker that sells their unit for LOTS more than it took him to make one.
