New Mini Booster Pumps.

PeteS

Looking at the very nice graphic on the website, it looks to me that as the booster is double acting, the high pressure piston and bore is exposed to the gas being boosted and the drive gas. This would mean you shouldn't pump O2 if you've used "dirty" gas as drive gas, or, you can pump O2 but you must only use clean drive gas.

So you need to use your "clean" 230 bar diving compressor to produce 10 bar drive gas. Not the most economic way of doing things. Or just don't boost O2......

Hi,

I think you could use the paint compressor but would be a good idea to filter the output. Personnally I plan to take drive gas from a spare cylinder filled with O2 clean air. Will post results on consumption etc when I have done some tests.

That would also be the plan for when on trips etc. I'm sure noone will mind me using the dregs from their O/C mix will they??!!

That's how I run my Baby Booster I tried a paint compressor but it was just not man enough for the job it couldn't maintain a high enough pressure at the volume required.

My "paint compressor" as you call them, is big enough for the job, and just about keeps up with the haskel....... Well ok, not quite, but the haskel does boost to "oh my god, quick turn it OFFFFFF" pressures very easily. But the compressor did keep up with the minibooster.

Clean filtered air is expensive. Compress all that air to 232 bar and then drop it down to 10 bar. Silly or what? Just price up some run time with all the filters that you need for clean air, and then go and cost a "garage" compressor. I run a "garage compressor", lots of dirty air but cheap, to run the haskel, and a triple filtered dive compressor for breathing gas.

And the air consumption depends upon the boost ratio you are trying to achieve. Cascade fill for lower air consumption.

The Maximator gas boosters page says that contamination isn't possible,
if this is the same booster.

exccept the booster being sold (or at least the ones already sold) were hydraulic boosters that were converted NOT gas boosters.. so internally they are probably different..

Greetings Gentlemen,

I have had my pump since July.

I have been running my booster using a paint spraying compressor, i bought it from machine mart at home.

Part No 000114052 Airmaster Compressor Tiger 8/35 £140.94
Part No 000120550 Clark Air Filter £ 11.74

Compressor is 200 litres per min, 10 bar 145 psi

http://www.machinemart.co.uk/product.asp?p=000114052&r=2007&g=102

It is important to use dry, clean air.

When away I use a diving cylinder and a first stage.

I did seriously over run the unit in an attempt to extract the all the gas from a 50 ltr cylinder (400 strokes per min.). I cooked the high pressure seal which resulted in Oxygen leaking out through the low pressure exhaust. A 20 min job to replace it.

It does the job, but care needs to be taken as with any high pressure air or oxygen handling.

Regards

Mark Elliott

I have one from Hydraulics Int'l. It is a great little machine. . .but your tanks can't be much bigger than 3L (it'll take too long to fill). I just get O2 and He from a local supplier and mix my own> MUCH cheaper than driving to the shop. The nearest trimix is 50 miles from my house.
The booster works off a scuba tank or a small compressor. Its not too loud if you use the tank.
All in all, worth every penny. ($1400)

PS. You CAN'T fill an air tank unless you get the proper filters. Its just not economical.
