Compressor Recommendations, Please

I have one of these Thumper Max Dual Air Compressor MkII, not bad for $164 delivered.

Neil.
I am curious as to why you want a high pressure compressor. Most will pump to around 110psi and if the tyres you inflate require less it is high flow rate rather than high pressure. I have a real cheap little compressor which will develop high pressure, 150psi + BUT it almost takes a day per normal 4wd tyre. The one mentioned above isn't real high but plenty of airflow at a good inflation pressure.

PX07. No other 12V compressor comes close (IMHO).
I have one which has done lots of work inflating BIG tyres over the past 14 years and has never been touched. It also runs my diff lock, so is often left switched on for long periods. It has a 100% duty cycle.
It has a small accumulator tank, can be switched on from the driving position via a solenoid and has a pressure switch that maintains it at between 120 and 150psi.

If you want more then "Endless Air"

Neil,
For many years in a previous 4WD I had a blue tongue compressor into a receiver tank with diff locks etc. and when I sold it I swapped the compressor part with a mate. It was a great compressor, 100% duty cycle.

Nowadays I do less 4WDing and don't have diff locks etc. but have a need for a compressor, firstly against my better judgement bought a "cheapy" to do the job when required. They either take forever and then overheat or have other issues. Last year on a trip I even had compatibility issues with air hose connectors (some genuine and some Chinese copies) when needed.
Came home and installed the latest TJM 100% duty cycle compressor into a receiver tank and changed every connector to a genuine "nitto".
Whatever you do you should consider the "Spend Once and Well" for your requirements.

Cheers
Jim

Giday Niel : I have MM air compressor 150 psi /160lpm & have mounted a 4 kg gas bottle on vehile ..
that gives me an air bank to clean out air cleaner etc , lot cheaper that the big brands !
super cheap have a compressor on sale ..ridge riderair compressor ..this is not the compressor i have on vehicle but is pretty much the same.. but i have just got one for anther job & is pretty good IMO , your brothers nick boab ...LOL

XTM Air Compressor 160LPM 150PSI
Supercheap $135 or $99.99 for club members

For me, I'll probably buy the twin head version from Kings. I've used them and they are very fast for what they are. Longevity is unknown.

If your want the best, it costs a little more but the ARB twin version wins any of the comparo tests I have read.

NeilM, I am intrigued...."waiting for 2 tyres to be pumped".... Is this compressor for a motorbike?

You will never find any portable or workshop compressor that produces a genuine 200 psi - and if you did, why would you want that kind of incredible pressure?

Workshop air compressors normally operate at 110-120 psi, air tools work satisfactorily at 90 psi, even the heaviest loaded truck tyres only take 115 psi maximum.

You should not use air dusters at over 60 psi or you risk bodily damage.

The important part of air compressors is ensuring their claims of actual Air Output, actually meet Free Air Delivery (FAD) measurements.

FAD is the measured level of air output (in CFM or litres/min) - as compared to "calculated air output" based on the air compressor cylinders, measured displacement.

Measured displacement is not the FAD capacity of the air compressor, FAD is usually around 50-60% of the measured displacement.

Then there are other factors involved, such as Duty Cycle (the length of time you can run the compressor before it needs to be shut down and allowed to cool) .

Air compressors generate enormous heat, and many have inadequate cooling - of both motor and compressor unit. Oil-less models are the worst for this.

The amount you pay for the compressor is generally a good guide to the output and reliability of the unit.

Buy anything under $120 and you will only get a very basic unit that will have low output, low duty cycle and a relatively short life. You will need to spend $250 or more to get a quality unit.

The better 4WD portable 12V compressors have good quality rubber mountings on a solid base, have an air output that meets their claims, and have a good length duty cycle - and preferably, a remote switch.

No point in buying a compressor that needs to be shut down every 5 mins because it needs to cool down.

There's some good units in the link below, just select the best you can afford.
