Best portable tyre pump

Likewise I am on my second one , gave my old one to my son
The Maxair 111 is are a nice compressor, the guage on the hand piece is accurate and works well on its own as a deflator They are not to bulky or heavy either and have a good warranty The compressor motor is a USA Viair

There are a couple of informative Utube review videos about on them

Another happy Bushranger owner.

I have a Bushranger Air Max III. Hasn't seen a lot of use, but it seems to work well. I did have a faulty inflator - the bit on the end of the hose with the trigger and the gauge - and had excellent warranty support direct from Bushranger. New inflator shipped asap. No proof of purchase required.

I also had confirmation from the chap handling warranty support that it was ok to remove the alligator clips and fit an Anderson plug. which he had done to his own unt,

The one caution I'd add is that this unit is made for the US market and all the threads and fittings are US sizes, so nothing you buy here will fit, at least not that I could find. Fortunately Bushrange do carry a full range of parts.

The Maxair III looks in every way identical to the Viair I purchased from the US 10 yrs ago. I purchased this unit as it was continuous rated.
Mine is now permanently mounted above the DS rear wheel arch in the LC200, works a treat airing up 6 tyres.

I'm fairly certain that the current Bushrangers are a rebranded Viair. IIRC the replacement inflator I was sent was branded Viair, as are a number of the spare parts on their website. Explains the US threads and fittings.

If Bushranger are simply rebranding compressors sold overseas, then who knows what PMK03's 20 year old unit is. They may have been selling Viair back then, but it's hard to be confident of that.

American thread size is probably AF, or might be SAE.

If the threads in question are 'piping' threads (rather than screw fasteners) I can assure you that all such 'NPT' threads are satisfactorily interchangeable with our 'BSP' threads in sizes from 1/4"(6mm) to 3/4"(19mm). Those size references being the nominal inside diameter of the pipe. Not a precise match but acceptable for most applications below 600psi.
However, especially in the smaller sizes used on proprietry fittings such as air chucks and gauges, threads are sometimes used that do not conform to piping thread standards and defy efforts to find matching fittings.

I have changed the outlet on my Bushranger & just used 1/4" fittings I purchased from Repco.
I removed the chuck style outlet & fitted a barbed fitting as it suited my setup better & just have the hose connected permanently to the pump.
Was a slightly loose fit but I used some teflon tape & it works well. No leaks.

When I spoke to Bushranger direct back around 2010 they told me it is an Viiar compressor they use but their own base, frame hoses etc.
On my old one I went to a hydraulic hise fitting place like Pirtek and bought a thread adapter fitting so I could use a Nitto fitting
I am happy to stick with the hose and guage supplied on the latest unit as it is much better

I found out the hard way that the Bushranger doesn't have Nitto fittings. I'd dearly love to know what fittings the Bushranger does have. Does anyone know? I went through all the fittings at Total Tools, and although I came close, ultimately I drew a blank. I was hoping not to have to replace the hose as well.

The warranty chap at Bushranger told me that all the threads and fittings were US, and not to expect to find anything compatible here. I've had personal experience of the incompatibility of NPT and BSP threads in sizes larger than Alan mentioned, so this made sense to me. I'm a little surprised to hear that there is compatibility in smaller sizes.

Hi Briste,
My extensive experience with imported USA process control instruments with American NPT threads was that they were closely compatible with BSP fittings in 1/4", 1/2" and reasonably so for 3/4". The diameter and pitch were the same but the thread form was a bit off.
Today, NPT fittings are available in Australia but not so in earlier times and we had to make-do.
When it came to the high pressures of natural gas applications we needed to import NPT fittings.

I have one of these and it puts out more than enough air to blow the dust and cobwebs out of my desktop computer.

It has a pressure cut-out switch that will stop the compressor at about 120PSI so I just run out hoses to reach the van and car.

I also have had one of these Max AirTwins,from 4WD Supercentre, Was a great pump.
I would finish airing up faster than any of my mates.

But it soon failed, all I kept was the hose & tossed the rest in the bin.

Can't risk it not working when I need it the most. That's when I bought my second Bushranger.

With the van & car it's 8 tyres each time. The Bushranger is a little slower but it never stops.

I've nearly always run two 4wd's at the same time - the Ranger has an ARB twin onboard and I can't fault it !

Seven years ago I purchased a Kings Thumper twin for $89 delivered to my front door - it's copped a flogging in my Mitsubishi van for 3 years and then the same flogging in my 200 for 4 years up until a month ago when it decided to give up - just like the Australian cricket team :)

Nearly bought another one for less than a couple hundred dollars but decided to go another ARB twin for the 200.

Like any product in life, some people have a long trouble free run with it while others have nothing but trouble after trouble after trouble. ( sort of like a wife really lol lol )

Happy inflations

Thanks Joe. Serious bit of gear, serious price!

Bob

Yes your right about the price Bob.
I'm tempted because our new traveling vehicle is a 716 Hino truck and runs higher pressures in the tyres than a most 4X4s. On dirt we drop pressures unless it's only a short stretch, so pumping 6 tyres back up to 80 to 90lbs is very taxing on any portable compressor.
I've done lots of forum searches but unable to find any first hand comments about them.

Judging by the air filter fitted to the unit, Joe, I’d give it a tick. Just need to find the “readies”?

Bob.

" I’d give it a tick. Just need to find the “readies”? "

Hey Bob - you could have one on each side of your rig !

The left one does your LH side tyres and the right one does your RH side tyres - no need for long hoses lol

More time to have a cold beverage - win win I say :)

Yeah Gaz, dip into my super before Elbow does! :-)
