| Well unless you have a lot of time then the small boosters ( jetsam baby booster, haskel sport booster etc ) aren't going to do it IMHO ,Some of us are waiting to see reports of this one New Booster In Town!!! - Rebreather World the compression ratio is very good & the fact it will boost with only 7 bar drive gas pressure means that hopefully it will be very easy to run from a small oil free compressor . HTH

| Hi Hugh, If you are for instance using a 7 l stage of 80% (149 bar O2 if filled to 200B) consider using a larger stage 10 or 12 but at a lower pressure thus requiring lower O2 pressure ? |

The amount of PRESSURE of O2 required will be the same in any size cylinder for a given % it will be the amount of LITRES of O2 that differs . ie :- 7L x 149 bar = 1043 Litres 10L x 149bar = 1490Litres 12L x 149 bar = 1788Litres all of the above would give 80% at 200bar If you lowered the fill pressure to give the same amount of Litres it may save a little but not noticable IMHO

| divetech (stanstead fluid power) midi booster DTB5C is quite good .....a bit bigger than a baby booster and fairly robust. used one on the boat all last season and proved to be up to the task. here: Gas booster - DTB5C Hazel

| Thanks for the comments ... Colin the new no-name Asian brand might be interesting (in a good or bad way)... but a 60:1 compression ratio on an unknown booster would worry me when I'm boosting O2 in the shed! Helen - thanks for the vote for the Stansted Fluid Power - they were / are the direction I am leaning. The only upside to losing access to my J's of O2 is that I'm going to be drinking more beer while listening to the whoomp whoomp of the booster! Thanks Hugh Last edited by japandiver : 08-04-08 at 01:23 PM. |
