Do I need a booster?

brinoz · 14th August 2007, 15:18

No you do not need one, you might want one.

I have a 30 ltr cylinder of oxygen (200 bar). 6 cubic meter.
I decant oxygen in my 3 ltr. For the majority of my dives, I accept to start with minimum 100 bar (inboard oxygen is not part of my bail out plan !).

So indeed I loose 3 cubic meter out of the 6. I pay twice the price for oxygen.
In Belgium, 6 cubic meter of oxygen is only 20 EUR !!!

Let's say I can get a booster for 1500 EUR. Moneywise, I have to make around 3000 dives to get my money back

Regarding money, it is not interesting.
Of course, it is a nice toy

I am sure of that.

Another point is safety ... but are you really top up your cylinder after every single dives or wait 2 or 3 dives

Regards
Bruno

But remember it boosts trimix as well.

I run a J of 02 a 15 of 18/45 a 12 of 18/45. a 300bar 12 of 10/70. Using the booster to blend 10/70 and 18/45 and air I can get a mix for any dive and fill my dills to 230 for multi day gigs.

When you work out the cost saving on the mix things start to make sense a lot faster.

That said its still a luxury not a necessity.

In Germany i pay for a 50 ltr 300 bar cylinder O2 40 € !!!! Ans so i must do many dives to get my money back. Ok the cylinder weights 70 kg...... but nothing is perfect.

If you can afford it do it but get a paint compressor to run the booster with because they use a shed load of drive gas. I am running a 10bar paint compressor through a oil and water filter. Its a slow but relentless way to pump from low pressure to high pressure. I just blew all my 02 cylinders to 220 bar from less than 90bar in my J. I think I ended with 70bar and four full 3ltrs.

Had I used bottled gas to drive the booster that would probably have cost me 60ltrs of drive gas. (ie 4X 15ltrs blown to 230bar)

Mark,

I'm in the process of aquiring a booster. I'm also thinking about a compressor. Any recommendations for paint compressors??

Cheers,

Pete

I am running a Clarke Rebel 30 10bar 25ltr unit (Machine Mart) as a compromise between size power and efficiency. A bigger 50ltr reservoir would be nice but I don't have the space.

It cost about £150
