My son tells me of this 12v Air compressor at a cost of $115. and pumps at an amazing 300LPM its twin cylinder available at 4wdsupercentres. You can read the details on their website. Is it too good to be true?? Does anyone have one of these??

Who knows Jeff, some specs on such things are a little over stated I'm sure, air comps and solar panels are 2 such things.
150psi / 150lt / min is good for mos 4WD tyres, and most twins are this spec, so you should be right with this one.

4WDSC ?
Just try and go into a shopfront, see the product, and buy it instore.
Online can be a crapshoot and after sales (after they've got your $$$) service is sadly lacking with this company.

Agreed Les, I generally look at these types of products fairly closely. And yes they do have a shop front in Sydney.

If it is anything like their previous model which was 150lt, I don't think you can complain. Have had for over a year now and used many times and it has been faultless, and these were only $95 delivered.
At the recent Adelaide 4wd show there were many rebadged versions the same as 4wdsc ones, just different colours and they all had the same specs. They were asking up to $299 for the same unit.
I personally wouldn't have any hesitation buying one.

I've had one the twins for about 6 months and used it quite often in that time.
For the price I can't fault it, its' extremely quick and has a constant flow of air. But as with anything motorized they will fail eventually so when on a trip in the bush I always carry a manual foot pump as a back up.

I've got the single cylinder version and it works good now. I bought it in store, took it on its first trip and it wouldn't turn on. I tried to take it back to the store and they wouldn't take it back. They said I had to go through head office which is total crap. Dealing with head office was an exercise in exasperation that got nowhere, the girl on the phone sounded like she had been inundated with complaints and couldn't give a rats. I almost just threw it out but decided to take it apart and found a wire solder join that had broken. I rejoined it and it was off and running.
Would I buy from them again.....not likely. The gear is well priced Chinese stuff with hit and miss quality control. If you get a good one you will be happy with it. If you get a bad one you can be philosophical about it not costing a fortune.

Lets not start a 4WDSC bagging session and stick with the question.
I have had a winch replaced by them, no questions asked, over the phone (incl rope & relay) because I snapped a drive tooth. Still got the old winch for parts.
Sometimes they do behave nicely

It's a compressor from the same company that didn't perform at all until I fixed it. Seems plain enough to me?

Michael, the business you purchased the item from is responsible for following up the warranty claims. They can ask that you go through their supplier (not always the manufacturer!) and in truth, this often makes sense for you and the businesses involved. However, if the issue of going through their supplier inconveniences you or costs you extra, they cannot insist upon this unless VERY clearly STATED and DOCUMENTED at point and time of sale.

Cheers,

Mark

The business I bought it from was a branch of 4wdsc. I know my rights, I'm in business myself. That's why it was so annoying that I took a few hours out of my day to drive back to the place of purchase for what I thought would be a simple exchange, and then have them point blank refuse and paim it off to head office at Silverwater which had already closed for the day. The ineffective phone calls and lack of email replies were the icing on the cake in my case, but not Malcolm M's apparently.
The actual compressor is fine now that it works.

Michael, I'm not defending them as such as I also think they are a pretty useless bunch and I think three times before I spend with them.
I rang Sydney support and somehow the call wound up with the QLD branch. They were brilliant. Nothing like the Sydney clowns I've dealt with in the past.

They pull up to 90Amps!!!
I've used the single cylinder ones (up to 45Amp) for a few years now, and feel no need for anything quicker.

They are pretty big, heavy and pull a heap of amps.
Do you really need to take 60 seconds of your 150Lpm compressor time?

I know a couple of people who have these and they are happy with them.
Sold under a variety of names at considerably more cost.

4WDSC usually sell them for around $109 so watch their deals page.

I have had the Single one for a couple of years now , it pulls 45amps , I was surprised how hot the power lead got , I shortened the lead as much as I could .
I have used it a fair bit all ok .

A mate bought the Twin model just yesterday

replace the power lead with heavier gauge wiring it will stop the resistance heat build up

Motor / alternator charging is recommended even for the regular compressors.
They all draw significant power, and depending on tyre size, battery circumstances, could be an issue even for a 150 / 150 regular model or even a single cylinder comp.

I checked my sons one, I thought the 90a might be the max but it draws 90a all the time even with no tyre connected. I was going to change the alligator clips to an Anderson Pole but they are only rated to 50a. He uses his second battery so no need to have the engine running.

Well if you have the engine running, you are pumping 14+ volts into it instead of 12-13.
The extra volts make a big difference to the comp motor speed which equates to a faster inflate time.

. . . and even though 2nd battery, why not have it charging / kept topped up with motor running ?
Well, safer than running from the main and not running I suppose, and it will charge up when driving again.

I doubt I would be getting 12-13 volts without the engine running when drawing 90 amps. It is plenty quick enough without the engine running. It is not running for long enough to worry the second battery, it is a very fast compressor. The advantage of not having the engine running is no Diesel fumes.

I know the modern 12v compressors are quite good but do they really deliver 300lpm at 150 psi ?
My V twin shed compressor is 8cuft/min at 110psi or 228 lpmin and requires a 2hp motor to drive it.
12v x 90 amps for the twin is around 1000watts where the 240v ac is pushing 1500w or close to that and is producing less volume and psi.

Just wondering if the stated performances are true, the physics indicates it isn't possible.

That would be 300lpm at 0 psi, like most compressor ratings.

No indication of output at higher PSI.

AH, so that must be 300lpmin of nothing at all. That is a strange way to rate something. A computer fan can almost do that too, no pressure but lots of flow. 0.150AMP flow

Why make it 150 psi? Who needs that pressure apart from divers.

RMB

You are right, Almost all compressors are rated that way as a benchmark.

A good compressor usually shows flaw rates at more usable pressures, like 20 psi, 30 PSI, 40 PSi etc, It's at these pressures that flow rate is meaningful.

the 150PSI rating has no real meaning if you directly connect tyres. 50 or 60 PSI is enough. However if you have an air tank then higher pressures such as 150 PSI is useful.

If you have an air tank, it will hold twice as much air at 150psi as it will at 75PSI. A speed advantage when you are pumping up tyres and for using air tools.

I bought my son one for Christmas. It burnt out on the 6th tyre on a very hot day. Took it back to the Brisbane store and they replaced it no problem. Second one is going fine so far. Very fast and did 8 tyres in a row coming home from a recent Fraser trip.

Thanks for the responses. I'll give one a go and see how it lasts the distance.
Probably buy the 150lpm for myself and the son gets the 300lpm.
