Gordon smith, in Canada makes a booster pump which will do the job but on cylinders bigger than 3litre it will be slow. Cost complete is 1250$ plus import. If you are interested do a web search on Jetsam or KISS. Or look here www.derwentelec.clara.co.uk/html/gas_booster.html

The small KISS booster does not quite give a 232 bar fill but the larger model or the Haskell range can do this. If you buy one of these plus a small hobbyist compressor (about 100 notes from Machine Mart) [to drive the booster] all you need to blend EAN/Tx is a couple of old air cylinders to get filled at your local dive shop.
This is many times cheaper than running a dive compressor plus all the filters. A breathing-air high-pressure compressor only makes sense if you are a club with enough members to justify it. Even a basic portable model is too expensive for the individual diver to justify. Furthermore most small compressors are utterly crap and need constant attention while filling, few have auto drain facilities and all need a carbon filter to remove the hydrocarbons at great expense and with a short life due to constant repressurisation and depressurisation. A typical petrol model takes half an hour plus to get to 200 bar..
Get a gas booster and buy your air at the dive shop - at 3 quid a fill it is far cheaper than you can do yourself..
