Just noticed in the latest Big W catalogue that they have a Max-air copy for only $89 !!! At that price its certainly worth giving a go (Big W have a great returns policy). Pity my ARB compressor is still going strong, albeit at less than half the speed of the Max-air types otherwise I would pick one up myself. But for those looking for an air compresor, at that price its certainly had to pass up.

Cheers

Captain I have spent many many hours this week looking at air compressors including the Big W Copy.
They are deffinatally not the same. If you have a look at the Max air, the air filter is at the top of the Cylinder/Heatsink and the BigW it is at the bottom. The Repco one is at the bottom also as well as a couple of others I've seen. The only one that looks like the Max air is the "Mega Grunt" being sold by AutoPro and Opposite Lock stores. AutoPro in Midland @ $169, opposite lock sell them for $200.
I don't know if the Mega Grunt is the same, however it is the only one that looks "identical" to the max air up close so it has the best chance of being the same unit. Repco's $299 rip off is probally the same one Big W are selling for $89.
After looking at a chart at ARB in Osborne Park that they have stuck up next to their busranger Max Airs showing "independant" tests of the copy's vs the Brushranger I've now made my mind up 100% that I will be going down to Opposite Lock Midland and buying the Blue Toung IV! All that their chart did was show me how crap the Max Air really is and how it fades like all buggery. The fact that it drops from 72LPM in the first few seconds right down to 60LPM and then steadily drops all the way down was not confidence inspriing. The Blue Toung can hold it's own and will keep doing it all day and all night if you need it too.
I also have some second/third/who knows' hand information about a guy infalting three tyres with his Mega Grunt and the whole thingbleepitself.
Woudln't suprise me as that what my chineese compressor has just done for the second time on the weekend.
BE CAREFUL GUYS, they are probally not identical, some of them might be, but some are deffinatally not. One thing the Chinese love to do is COPY, steal someone else good idea and cheapen it for a fast buck.

Oh yeah the supercheap Auto $179 job that was mentioned earlier also has the air filter down the bottom so it is deffinatally different to the max air.

Hi Jeff,

I hear what you say about the original max-air and their copies - all good info.

But one thing, you say the ARB comparo shows that the max-air flowrate drops as the pressure rises. Thats normal and ALL compressors should do that! If ARB is showing a chart where volume pumped stays the same as pressure rises for another brand, somethings rings alarm bells here.

A piston compressor pumps a fixed volume of air, so if you double the pressure, the volume halfs, hence 1/2 the flow rate when you have doubled the pressure - good old Boyle's Law at work for you P1V1=P2V2.

Not too sure of the fine print on the chart, but might be worth a closer look.

Cheers

Captain

Good info there Jeff - I agree with what you said before - its all very confusing! :)

Captain - if i understand what you just said correctly, I agree - but - remember the more pressure, the more load on the motor, a good compressor (motor) would be strong enough to keep pumping at the same speed where as a cheaper (weaker motor) would start to slow down with load and thus flow rate goes down....

Cheers,
Dave

Hi ya Biscuits,

Yep, totally agree. Its only if the compressor is "perfect" will it simply half the volume as the pressure is doubled. This is where the better quality compressors come closer to that, while the poor ones taper off rapidly as the pressure rises.

Cheers

Captain is absolutely correct in what he says, the volume will reduce as the pressure increases and conversely the same, pressure decreases volume increases.

If any manufacturer or seller depicts or tell you these are constant values then they a Bull$hiting you, pure and simple.

This is quite normal and in the compressor world you need to consider the volume supplied at the pressure required.

Mr Chen3
I fail to see were Jeff has made a racial comment.
He comment is valid in respect to "One thing the Chinese love to do is COPY" etc.

The issue of breaching patents and copyright by Chinese companies is very very well documented and is a constant issue between the US and the Chinese government's.

Thanks John,

Can I say American are cruel and inhuman as the way they invaded Iraq and treated these innocent prisoner, these are all well docuemted as well. how does Australian state their action in the invasion and their past history. Why did we see "SORRY" in the sky a couple years ago. We all know these.

This is a very popular 4WD forum and any comments on race or nation may cause unnessary debate and argument. Let people make their own choice on product their preferred.

Chenj3....GET A GRIP SUNSHINE!

I thought we're talking about air compressors.
If you can't have some informative input or comments go somewhere else!
"One thing the Chinese love to do is COPY, steal someone else good idea and cheapen it for a fast buck."...this is fact, nothing to do with race, colour or anything else.
Plus you are contradicting yourself aren't!

"Can I say American are...."
then you start about
"any comments on race or nation..."

Thanks Dogart you took the words right out of my mouth and saved me typing them.

It interesting to see who really is the person who is quick to throw direct racial slurs at others.

Mr Chen3 I would also add that people in glass houses should not throw stones, history would show that the Chinese are a nation that has been quick to throw its weight around also in a highly questionable manor.

Thanks John and Dogart for sticking up for me while I was putting my feet up after the accident yesterday, I appreciate it.

Now.

Chenj3, mate I will appoligise if something I said upset you.
However, I will not retract what I said as I have been seling chinese products and dealing with chineese, taiwanese and korean manufactures for my entire working career and what I say is undisbutable fact, if you don't like it tuff.
As for throwing around racial issues, mate you brought it up and if you think that I am "racist" for what I said well that's just your opinion. I did not say that chinesse were bad people (although I could have brought up many examples of nasty, selfish and outright imoral things I have seen them do in business and life but I won't and didn't here on this forum), I did not attack anyone or any group.
So if you would like to take my advise, drop it and let's get back on topic thank you very much.

Just for the record, original Bushranger Maxair is made in China as well. Most of the copies i have seen originated in the same "Max air factory". The story about Maxair "copy" is pushed around by TJM and Bushranger to protect their monopoly on this product. All importers of this compressors get them from China by a container load. Cost is 52.00 per compressor.
Next time you run into Maxair ''copy'' chances are is it one and the same compressor. I have opened Maxair and so- called copy and inspected internal parts. They are one and the same. Story about plastic rings in ''copies'' of Max air are just a lie.

Goran, very interesting comments there.
Let me ask you, which one of those "identical" air compressors did you pull apart?
As I have seen several different ones so far in my resarch, not only are at least some of these probally different on the inside, they absolutally different on the outside and the fact that you do no know this means I do not hold much credit to your above comments.

I am talking about the ''Max Air'' without the sticker i got from ebay. It is identical on the outside to max air. It just comes with different air hose. I AM NOT TALKING ABOUT SMALLER UNITS like grunter, etc. I have on good authority that if the comressor looks indentical on the outside it is one and the same Max Air. Same factory in China makes them by the container load. My mate has Max air (Bushranger) and i am telling you it is the same on the inside as well. The story about weaker parts and plastic piston is nothing more than what i stated above. Just a con.

The others are not smaller and look the same (compressor wise) however there are subtle differences. You can't be assured that they are the same inside without looking, even products made in the "same factory" are not necessarily made from the same components. Is it teflon coated piston? is it made from the same alloy? etc etc?
Not saying that the one you bought off ebay is not the same, just saying that even if it is, does not mean that "if it looks like a max air then it is". Letting people know not to just jump in and buy whatever looks the part. Looks can be false. As I have said before, different importers what to pay different prices, the chinese manufactuers are NOT stupid, if someone squeezes the price for 500 units, they cheapen the product by subsituting parts here and there. Look I've been there and done it as I have stated before, I know what goes on.

I have one the same, as stated above I got mine from Super cheap but is exactly the same as the Big W one. I did a timed test just yesterday on it. I deflated my 31x10.5s to 17 psi, the compressor took 2 min & 15 sec to inflate to 38 psi. These figures are pretty close to the max air figures. Not sure how long it will last but so far so good.

G'day Spook,
Inflation time/s are affected by a number of factors too.....
Condtion of battery (and whether engine is running)
Ambient temperature
length and size of cable to compressor
etc etc

Also, load your truck up like you were away camping with the extra 500kg of crap, put in a couple 100kg blokes and a full tank, then pump 4 tyes up in a row, then see how long the last tyre takes to pump up.
That's where the difference will be.

I got mine about 12 month ago from Motormate (South Road, SA). It is the EXACT same Max-air with the higher air intake. have had no problems with it whatsoever. It is actually in the Motormate flyer from yesterday for $149. Have a look here, and tell me it is not a Max-air.

here's apic from the Big W catalogue.

http://www.bigw.com.au/catalogue%2028-08-04/site/pages/24/b.jpg

the only diff to cruiserheads one is the lovation of the handle on the front!
For $89 get two of them, pump tyres up in half the time or have one as a backup.
And as said before, if it stuffs up bring it back no ?'s asked at Big W.

Not a bad idea with the two of them, but they are deffinatally different to the Max Air, as I said they don'thave the little rubber cover that goes over the air outlet, neither do they have the rubber cover over the power switch, neither do they have the air filter at the top.
Personally, I'm still going to save my $350 and mount the blue tounge under the bonnet plug in my air hose to the front grill and have a coffee with the peice of mind they'll be done and I can just relax while it takes care of it for me.

Hello Jeff

My Motormate does have all of your above stated!
It has:
- a little rubber cover over the air outlet
- a rubber cover over the on/off switch
- the air filter at the top!

I am quite convinced it is the VERY SAME THING and the Max-Air! Have a look for yourself!

OK, just bought the "Max-Air Copy" (and that's what I'm calling it!)
from BigW for $89.77. Will give a good workout over the weekend.
I'll see how many times I can pump up my 265/70R16's from 18psi to 40psi,
until it cuts out. Well that's the theory anyway.
If it's crap. bring it back, but I'm sure it will do the job.
Supercheap have EXACTLY the same for $179.00!
The money I save I will buy a set of Stauns. Then I'm all set. WOOOHOOOO.
