[PSUBS-MAILIST] Cornelius compressors

[Alan James via Personal_Submersibles]

Thanks Steve.How easy would it be to adapt a rebreather O2 feed system to a submarine?I believe APdiving in the UK did this for James Cameron's sub.I'm building a one person sub about the size of Cliff's R300 & because of the small size,wanted a system that responded quickly to O2 deviations.I envisage the system as having a constant flow of O2 at a rate just below my minimumconsumption, with a top up from readings off 3 O2 sensors.Cheers Alan

Hi all,I know Hank uses a Cornelius compressor and I think others have enquired after them.  In a nutshell, it's a small/lightweight (~60lb?) high-pressure compressor no longer made, originally used by the US Air Force in aircraft - so it's pretty well spec'd.  Also by default runs off nominal 27VDC - so highly suitable for install in a PSUB, if you can handle the current draw, noise and 2cfm flowrate.
Well in the course of my business, I sold a SCUBA nitrox mixing stick to a guy in Canada who mounted it on a Cornelius compressor - see a picture of the final setup he sent me (if the recent discussions of email vs Facebook haven't put you off!):https://www.facebook.com/tfmengineeringaust/photos/a.754931991306953.1073741830.754476911352461/858648047602013/?type=3&theater
Anyway, we got to talking and he said he got the compressor from a bloke in Florida.  I made contact and discovered this bloke has a whole lot of them that he is slowly setting up and selling as fully functional breathing air compressors (they are old but apparently well preserved and have only a few hours - he runs them in).  He also has parts as well for anyone like Hank who already has a unit.  I'm contemplating bringing a few into Australia to on-sell.
In case anyone is interested, his name is Paul Deverell, with email pauldeverell at ymail.com and phone number +1 786-367-3365
Cheers,Steve
