air compressors - the fastest - or other options?

Endless air or copy, belt driven from the engine, 8 cfm, will pump up anything and drive a rattle gun etc. Presume the 4.2 TDI is a GU? If so, you will need the proper brackets to fit one, give me a MM and I can give you some more information.

Well, I've done an interesting comparison between the Projecta Typhoon and the new ARB compressor.
I'd been using the Typhoon for about 12 months, and had been happy with the speed of the thing (claimed 150 litres/min)....I found that I usually over-inflated my tyres because the thing pumps so quick. Then I had to let a few psi out again to get the right pressures.

Recently I had a rear air locker fitted complete with the new ARB compressor and inflation kit.
ARB claim 75.1 litres/min @ 0 psi and 61.6 litres/min @ 29 psi.
This compressor looks very well built, but geez it's tiny....half the size of the Typhoon. It looks like a toy
I honestly thought the Typhoon would kick it's butt.

So here's how I went about testing them against each other.
First I let both front tyres down to 16 psi (MTZ's 285/75/16)
Then I connected both compressors to the same battery, and ran the motor at a fast idle, so both compressors would be getting the same voltage. Connected the compressors to the tyres and started them up at the same time.

Ran the comps for 60 seconds, and then checked the pressures:- ARB 27 psi. Typhoon 26 psi. Not much in it at all.
Ran the comps for another 60 seconds, and checked the pressures again:- ARB 37 psi. Typhoon 34 psi.
Ran them for another 60 seconds, and checked the pressures again:- ARB 44 psi. Typhoon 40 psi.

As can be seen from the above figures, the Typhoon falls away a bit when the pressure gets up.
But I still think it's probably the best bang-for-buck compressor on the market today. From memory I paid about $160 for mine....bloody good value, if ya ask me.
But the ARB compressor is seriously just a good thing.

Not a super scientific test....I just thought someone might be interested in a real world comparison between 2 of the most popular compressors on the market today.

Boc,

Depends on how much you are prepared to spend.

The absolute quickest way is by way of an "Air-Up" portable compressed air cydinder. Prices for these have come down from $800+ to around the $580 mark, which is not that much more than the cost of my portable "Big Red" compressor.

For the occasional tyre pumping exercise, a 12 volt compressor is the usual way.
Fastest is not always best either. If the pump has a shorter cycle time before it cuts out, or bleep s itself from overheating, then you have wasted your money.

If I was buying one today, I think the ARB compressor would be my choice.

Bill.

Hi Boc,

I recently bought the new ARB compressor and it is every bit as good as the advertising. It replaced my 14 yr old ARB compressor which was still going strong, albeit not as quick, after years of abuse. If the new one lasts half as long as the old one then it will be a bargain!

Cheers

The Boss Air Compressor would be one of the fastest 12 volt compressors available. I've had the predecessor to it (Big Thumper) for over 6 years which has often pumped up 10 to 15 tyres in a row. Only issue is they are very big making them hard to mount. As a comparison I reckon they are about 50% faster than the latest ARB compressor which is probably the better choice if space is at a premium.
Cheers Craig...............

I recently borrowed my brothers new ARB compressor. Very impressed. Took the tyres from 25psi to 40psi in a very short space of time. Next time I use it I might actually time it for comparisons. When I'm serious about buying a new one it would be close to top of my list. Only down side would be letting it cool down enough before you could put the hose and cables back in the box without melting them. So until my brother remembers where he left it, guess where it will be.

Cheers

This is the best compressor on the market for my money

I have this mounted in the truck bed with a stainless steel tank made from 50mm stainless steel pipe .. two length of pipe about a meter long.. not a big tank but it works a treat.

I have 6 tires to pump on the truck (33" ones) and have compared specs and reviews as well as tested various compressors. Most specs a plain lies as far as duty cycle and flow is concerned and some specify 100% duty cycle at free flow (what a joke). I use the compressor as an onboard airsystem and drive a socket wrench, rattle gun, airhorns, exhaust brake and of course compressed air to clean out the corners from the red dust.

Everything else is pretty much a toy .. I pump up my 6 tires from 22 psi (lowest I usually go) to 50/60 psi in less than 10 minutes and that includes removing the valve caps and putting them back on on my dual wheels in the rear. Most other compressors I see out there when people pump up their tires at the same time struggle to fill 2 tires in the same time sometimes not even 1 ..

well ... you said you want it quick ... this is it then ..
good luck

I havent bought local 4x4 mags for a few years now, Has there been an unbiased test of all quality compressors in the last few years??? Michael

I've always had 2 pumps - easiest way to double the speed.

In the 70's and 80's it was two handpumps - so a mate could help out.
In the 90's I carried 2 Kmart pumps.
Since then its been 2 decent pumps - one's been a Blue Tongue under the bonnet and I currently carry a $125 Terrain tamer Twin Cyl one in a bag with battery clips.

The second pump is there as a backup; can be used on other vehicles, and I lend it to my kids if they go camping or on their own trips.
