Ozito C02 System

[OBBob]

Anyone tried these?

Portable C02 canister to run air tools. Know it costs about $150 to start with then you have to change over canisters. Just wondering how long they last, how much is change over etc.

sounds like a good idea but a bit expensive especially if you have to kep paying for more CO2. I have always used a LPG botttle filled with compressed air.

I used to work for a guy who had a large collection of antique cars they were spread all over the city in garages and as the tires might be down of even flat we always went to them with a 9 kg LPG bottle full of compressed air. We filled it up from the compressor in the garage at home and if we needed to we then went to the nearest petrol station and refilled. It would pump up 2 or 3 19" tires without refilling.

I use one if I'm using my nail gun inside the house, saves dragging the compressor upstairs I just fill up the bottle with my hose from the retractable reel by opening the valve tap and when the pressure equalizes (about 100psi) I close the tap pick up the nail gun hose and bottle and go wherever I want to.

Quick, quiet and real cheap. I used my old out of date LPG bottle.

Yeah ... I did see a compressor that came with a small portable bottle once. Wonder if I can get an LPG bottle from somewhere ... any ideas ... guess BBQ bottles would work too?

Durwood, that's a very clever idea, especially for using with a nail gun. Have to try that, I have an out of date LPG bottle here.

Thanks for the tip.

Are they not out of date for a reason or do you just get them retested and put back in date? I guess filling to 100 psi is a test of sorts.

You can get out of date LPG cylinders retested here in QLD but the cost is almost the same as buying a new cylinder especially if you wait till their on sale somewhere.

I know that K-Mart used to sell a small compressor that cam with a portable sub-tank. I think it was Arlec brand but can't remember

Yes, it's called inertia Although with the price of gas bottles being so low these days, you may as well buy a new one, or use the swap[over service.

[durwood]

My bottle is over 30 years old.

They are rated at a lot more than the 100 odd PSI I put in it.

Our local tip takes old BBQ bottles and you can get them for a few bucks.

I'm sure if you have a BBQ the bottle is getting to its limit of 10 years anyway so why not buy a new one for the LPG and use the old one.

In theory it could be rusting away and be a bid dodgy but I opened the tap when it was empty put air in it a few times and then let it out.

If you then tip in some oil used for compressed air and shook it around it would stop any further corrosion. I saw cylinder cut open after its time was up and it was pretty good inside just a few rust stains.

That's a brilliant idea durwood. About how many fixing nails would you get from one of those swap and go bottles?

I used to have one of those little portable compressors (as well as a big pig), but there was no storage or cut-out, so you'd have to turn it on and let it run all the time (dancing all over the floor) when you were using it.

[Make it work]

I think Kincrome have a portable cyclinder.

I like the 9kg cyclinder but there is another air storage, a wheel and tyre with a seperate outlet drilled into the wheel, but I don't know if I'd be game to take it to 100psi. When I was at school the dad of one of my mates had this setup. He'd bought a compressor with a damaged tank and improvised.

Then there was another mate who got sick of being run off the road on his bike so he got an air horn and connected it to a slim Primus bottle filled with LPG, man that was loud, sounded like a truck and looked awesome at night when we used to set it alight.

MAN we were so stooopid.

Not sure pawnhead, I have never run out but I've only ever done small jobs with it. I will do a test on the weekend.

I usually use the compressor if I know I will be doing a large job.

I used to run airbrushing classes and most of the students couldn't afford a compressor set up so we used to suggest they use a tire pumped up to run their airbrushes at home. Made it easy for them to do small jobs.

One guy had a tyre he used to pump up at the local service station and then take home where he put it under the bed in his room and sprayed his artwork ( he was doing crash helmets). I suppose if you used a tyre such as one for a truck you could safely pump it up to a high pressure and get a good run out of the air stored in it.

[durwood]

I have just filled the LPG bottle and connected the brad nailer,

I got to 127 nails when I ran out. If I couldn't get 200 I think I would be suprised. I was guessing about 50-60.

What your tools actually use in air will determine what you can do, my nailer is only a small one.

Just noticed that the bottle is galvanised, most of the new ones are only painted so are probably bare metal inside. I would think the gal ones would have been totally dipped and therefore are coated inside as well. could be why it still hasn't sprung a leak in all those years.

This is the pro version. http://www.air-up.com.au/construction.html The difference is the pressure level of the cylinders which will supply a lot more gas than something pressurised to 120psi, & therefore a higher nailing capacity. Also, with this system the regulator eliminates freezing which is a problem with the Ozito model. The inherant weekness with this system is the need to regas the cylinders, no problem if you live near a filling station.

There was a review in the magazine contractor builder that was very positive. From memory it was something like 1500 18G brads to a cylinder and Bunnings will swap cylinders for $15. Given the convenience of the system, it looks quite attractive.

I have the Ozito system. Unless you are shooting a nail a second until the bottle is empty, (Or you held the bottle upside down while firing) you wouldn't have a freezing problem. Cost is $150 for the reg and backpack, hose, connectors etc. Each bottle is $80 and $15 to swap for full at Bunnie's. So it isn't cheap. I have gone through one bottle, but I only got halfway through before I put it away with the hose attached, and lost the whole tank. Regulator must be detached when stowing away.

I wouldn't use it everyday, for everything. I've got it in my kit with guns and nails so I can fix something easily. For all day every day, I'd use a compressor. I'm still looking for one that's not a backbreaker, and isn't too loud, or at least the quietest.

My personal preference would actually be a High pressure air system. This is already in use in the States, but to import myself a setup would be $600-700. You'd need access to a dive shop or high pressure compressor. Tank is a little bit bigger, but it's a carbon fibre tank, and is filled with air, not CO2.
