Outer Limits 4x4 Board

I have an XL-7 so a tank and compressor is hard to fit due to space. I have been looking at the air-up CO2 bottles, mounitng the bottle on the rear door instead of the tyre and using that to run pump the tyres, run the rattle gun etc.

It would also be nice to be able to put in the 50 whn it is on the road.

What are peoples thought on the air-up product?

I will be putting one of these in the New buggy!

I have seen and used these at many comps and trail drives. Beebee from this board is supported by Air-up and trust me it gets some use!

There are arguements for both sides but from what i have seen of this products it will really suit your needs.

The thing that gets me is that it can pump up a 35 inch tyre from something like 15psi to 30 psi in about 10 seconds now that is heaps faster than any onboard compressor i know of.

PM Beebee as he will be able to put you onto the right people!

I am keen foir one also but where do you refill them??

If you run out of air during the competition... how do you go about refilling b4 the next stage?

Im keen also.. but concerned about the refilling..

I spoke to the air-up guys at TT. I am looking at the 2 bottle pack with the mount bracket, hose, regulator, handle and tyre inflator for a little over $1k. The refills are $20 a go, I will get 20 tyre inflations out of 1 bottle, so 5 trips off road.

In Sydney, the dealers and Mannell Motors and Snake Racing. You can get them filled at dealers (obviously) as well as some home brew places.

Greg

does the bottle frezze up at all from over use ?

i know mannels and snake racing can fill the tanks,

can places like boc etc do them aswell ?

Don't know about BOC....i'll ask.

The tanks have to be used vertical (or within 30 degrees of vertical) or the liquid comes out and damages the regulator.

Aparently they use a 'special' regulator that does not freeze up and gives high flow rate.

I have been using the Air Up system for around 12 months now and the output (31 cfm) cannot be compared to any other portable compressed air system. No to mention that it is FULLY portable, but also tackles the high flow tasks of reseating beads and running air tools with ease.

The specially developed high flow regulator that is part of the Air Up system will not freeze up. That is the primary difference between it and a regular CO2 regulator as well as the increased flow rate. The bottle will form ice on the outside as will the hose from excessive use but this is part of normal operation. It is not damagaing in any way to the components. And if you're really smart, you'll wrap the supplied coiled hose around a cold can whilst you air up, and by the time you're finished, you'll be able to sit back and enjoy a coldie whilst you wait the next 15-30min for everyone with electric compressors to finish airing up!

The thing that gets me is that it can pump up a 35 inch tyre from something like 15psi to 30 psi in about 10 seconds now that is heaps faster than any onboard compressor i know of.

are you for real POS, or exagerating? That is faster than any of the air outlets at any of the service stations i've ever used. Sounds like a top setup though.

I couldn't remember how fast it really was, hence the "something like"

I looked it up -

Performance Specifications
Tyre Size PSI No. of Tyres Seconds
30x9.5 R15 15-32 psi 20 17 seconds
31x10.5 R15 15-32 psi 15 20 seconds
35x12.5 R15 15-32 psi 8 32 seconds

OK i was a bit off, but its still farken fast!

opps

BOC and the other commercial gas suppliers are moving towards a rented bottle only style of bsuiness plan. Basically, if you own your own bottle, they won;t fill it up for you. They will only fill up rented bottles.

I was talking to a guy in a gas outlet the other day and he reqkens that BBQ and camping bottles will be going the same way, you can only get bottle swaps and they will all have the 9Kg (POL???) type of fitting? Anyone else heard of this?

POS is almonst on the money. The output of Air Up is 31 CFM @ 200 psi which compares to about 13 CFM max from a single phase compressor. The only other portable compressor that compares with those flow rate figures comes with a tow hitch and wieghs around a ton - not quite as portable as Air Up!

I`ve seen it, I like it, but at $750 + refills every few trips I an`t sold on one yet.

after checking them out, they are an awsome idea, but the dollars for many of us can be spent on something far more practical,

if i did have the money thou, id probably have one,

Out of curiousity, how do the DIY aircon compresser setups compare to the arb/big red electric compressers ?

Not even close to one another

say i have my own co2 bottle can you buy regulators on their own

Guts wrote:Not even close to one another

Aircon compresser setup costs like $2-300

If you can buy a decent electric compressor for that much then why do people bother?

i take it your talking about the enginer driven compressor systems

they push alot more air than any of the portable electric ones you can buy (in a reasonable, car mount, size.

With refilling bottles you get the same issues which are raised with scuba diving. Bottles have to be inspected regularly and regulators serviced etc. If one ruptures there would be a big mess I imagine. I would say companies like air liquide and boc would rather just use their own bottles which are regulaly checked and serviced etc so as to avoid any legal problems which could arise.

just as a point

there are Co/2 regs have heater elements in them to stop the freezing up

or you can get external heater elements too

The answer for this Question is Air-Up is a hi tech fire extinguisher running at about 800 psi unlike a dive tank that is at 4000psi. Testing is required every 10 years. The regulator has a limited lifetime warranty requiring no servicing other than keeping clean. Cylinders should always be secured at all times. As for ruptures we all can hold a fire extinguisher without any trouble. As for the big gas company's they are interested in getting your rental money only.

Yeh, thats a more likely reason. Thats why its handy to have someone in the family who works for one

ok question...

i buy one..

who do i get to fill it up for me??? when i go 4x4ing...

say ... i spend a week at cruiser park... and i have an air up system on the back of my pootrol...

it gets used now and then.. and im out...

where do i get it refilled and what cost each time??

How convenient is the refiling location??

Here's the link to who sells them and who fills them.

No, Guts is saying the engine driven compressors have heaps more grunt than the electric ones. So so in air output thay are "Not even close to one another"

If they are just oxygen filled, couldnt you get them refilled at diving shops or use a diving tank instead

It is Carbon Dioxide not Oxygen

is carbon dioxide as good to have in your tyres?

like i know Nitrogen Oxide is better than Oxygen as it is more stable over a larger temperature range and also does not bleed through rubber as easily as oxygen, is carbon dioxide better or worse than oxygen?
