Portable compressor

I'm with you Kazza,
The Dual Thumper. Big capacity and throw away and get another at the price if needed. I've had mine for a couple of years now, used it fairly often and not a bit of trouble. I've fitted an air gun and gauge to mine so now it cuts out when not pumping keeping it cooler.

Interested in your comment Scott & Sally

I have just ordered this Car Vehicle Air Tire Pressure Inflator Gauge Dial Meter Monitoring Teste... . From what you have said, the pump will shut off after releasing the trigger, is this right?

I was actually going to add a remote control relay to turn the pump on and off, if what you say is correct I don't need one.

This is the New DC 12V 10A relay 1CH wireless RF Remote Control Switch Transmitter+... with the relay contacts across the on/off switch.

As I need to reach the caravan tyres, I also grabbed one of the Blackridge Air Hose, Recoil - 1 / 4inch X 50ft so both hoses will get me to the spare on the back of the van.

No Kazza, the compressor will not cut out when you release the trigger on that, or any shut-off valve, unless the compressor is fitted with a pressure switch.
If Scott & Sally's compressor cuts-out then it has a pressure switch.

For the purposes of tyre inflation, there is little point in having the compressor cut out anyway. The "idle period" when moving from one tyre to the next is short and the compressor is unladen. This means that the compressor is free air pumping which generates virtually no heat and the dc current drops to a much lower value than when compressing. Furthermore, the flow of uncompressed air would tend to cool down the already hot compressor.

There is even a subtle benefit from having the air flowing free when the chuck is not on the valve. It ensures that sand/dust will not accidentally lodge in the chuck.

The dual Thumper that I have apparently does have a pressure cut out switch. I only found this out when I fitted the air gun to it. As far as heat goes this thing pumps my tyres up so quick it hardly gets a chance to get hot.
Cheers Scott

Thanks S&S, will try it when my trigger arrives otherwise I still have the remote on/off I can fit or as Allan suggests, just run it with the trigger open.
Gota love this place. :=))

I have one of these Thumpers too, and it's brilliant. Was as cheap as chips and all my tyres are pumped up whilst my mates have hardly finished one and then I pump up theirs' as well!

Ditto, I've had an ARB one for the past nine years and it's been faultless. About four years ago I got them to fit it permanently under the bonnet, then moved to under tray on latest vehicle. Still going fine.

I doubt if you can believe a 4WD industry identity. It is unlikley the factory which makes the same, same, same, compressors would go to the trouble of making and fitting lesser quality but same sized parts to only some of their same same compressors.

It is highly likely the importers see a possibility to increase price along with claims of being better, knowing full well no one is going to do, or allowed to do, a dismantling check before purchase. Everyone is at their mercy or lack of.

For durability and size/weight reasons I have a CMK12 ARB and use it T hose linked to an old Fire extinguisher for use with an air grease gun and impact gun if required.

"Best to have the vehicle engine running whilst inflating."

Recommended for any compressors, they all draw high amps.

Specs look ok, and if on special (like now) not bad value if it's a decent build.

I paid $150 (show special price) for my Bushranger MaxAir 11 compressor 12 years ago...compressor has several times pumped up 8 large 4wd tyres and 4 X caravan tyres (12 tyres all up) from beach to road pressures one after the other without any heat cut off issues, and couldn't say how many times it's been used doing just my 4wd...i'll happily go same brand again if I ever replace this one.

ARB make crap as well. I have their lockers to prove it.
Just because you paid a heap of money for it doesn't necessarily make it quality.

I keep my ARB comp for lockers and use a Chinese thing for the tires - its over 8 years old and still doing the job. My son has a similar one that's around 7 years old and its still working.
Neither gets looked after too well and neither gets a cool down period while pumping. If one dies then we would use the other but that has not happened yet.
Can get 6 of them for the price of an ARB.

Do a google on compressor comparisons, plenty of them out there. Not everything without an expensive label is crap.

Most of the ARB air locker issues come down to poor instalation.
Hardly a ARB fault.
You do need to give them credit where its due.
Oil up the line was a poorly designed o ring or over time... perish
Which will happen to anything in a hot environment.
I have replaced the old o ring design with new design
Not an issue since.
At least they actually fix issues on some of their products with new designed fix such as the o ring

The one way valve was a patch fix they did sell

But i just done cape york and wanted a strip down and vehicle check over
Fixed it while on the hoist ?
Replacing the seal is super quick too


I have also had the crank bolt on the new arb compressor fail
Of which LONG out of warranty !!!
ARB warrantied the work without asking for proof of purchase or what i used the compressor for.
Fixed for free
No hassle or a fight
Very very easy to deal with on that one !
Cant ask for more than that

But i will say , their leaf spring setup is very poorly designed
As ive had 3 leaf spring failures in 3 years or less.

Seen several Renegade compressors owned by mates die at a fairly early age on jobsites I've worked on over the years.....no idea if those smaller ones are similar quality to thier big brothers or not though.
