I am about to buy a 7.5 tonne DAF, and need a compressor for it.

Any ideas - the two main differences are that it is 24V, and that the tyres are obviously a lot bigger!

Sam.

As time marches on, so one's desire for space and comfort enlarge... (I attribute it to age, but it's probably the desire to oblute in privacy :-))

Surely the DAF will have air assisted brakes and therefore a good engine mounted compressor already?

If not, Lee (Highlanderhead) should have taken delivery of his Flash Air by now, you could link up with him and try his out (I think his is 12V but it's available in 24V) You'll be pleasantly surprised...

Hi yes eventually bought the flash air 12v. Took 4 weeks for it to arrive though. My first thoughts when I took it out the box was its not very well made, but then for £200 what do you expect. Secondly what they never told me when looking at the specs on their webside was the fact that the figures where for the 24 volt not the 12v. So the 12v only pushes out 2.12 CFM. During the 4 week wait for the airflash to arrive, I decided to take on my own project and build my own. I bought a york air con pump off ebay from the USA and a 4.6HP 3500 watt winch motor. I have already started the project, building this monster which will push out 12cfm at 100psi. This is made possible by the high power winch motor that spins at 3000rpm no matter what the load, its a serious bit of it. So far I have mounted the compressor and the motor on a piece of aluminium, and I am just about to couple them together using a spider Ruland Coupler. It will then be mounted in a aluminium flight case. i will post some pics when the project is completed. All in all it will take 40 sec to pump a landi tyre up from flat maybe even less. As far as the FLASH AIR goes well its ok but I wont be taking it with me on my trip, only for short local trips in the UK.

Success with the home-build?

Sam.

Anyone used one of these yet ?

No, but 12 cfm is going some, thats better than my garage compressor!! I wonder how much spondoolies. pretty heavy @ 100lbs, but possibly less than 2 seperate units, although all hanging in front of the front axle

Yeah Moggy, I wonder how much !!! no change out of a grand (£) I bet.....I might enquire just to see......

- and 5cfm @90 psi - so say 7-8cfm @50psi ??? - id like to see the detailed spec sheets and the current draw....

For comparison, the Warn XD9000 on the Disco weighs 78 lbs and the Superwinch X9 on the Defender weighs 82 lbs - so 100 lbs aint bad for a combo...

- quite a decent winch too, looking at its features - similar to the XD9000 - which is a good winch - with up to date gubbins - and of course they do a 12,000 lb version.

be intersting to use one in action and see how it copes for real at West African temperatures - though Warn generally make fairly good gear - the video says it can run as a compressor continuously for 30 minutes - thats a good few tyres @ 8 ish cfm.......

I bought a cheap little Jumbo air comp for 10 squids and it works I got the fittings and hose and air gun when I was in ireland i got asteel worker to make me a neat little tray that sits over the wheel arche in the back of my toy hilux as the compresser is 240 volt I am going to search for a 600 watt invertor to run it has any one down anything like this ? when I let air in the tyres down and plugged in to the mains from the house worked no probs but i noticed that the motor got hot also the hose end that clips to the compr, also I need some sort of a reel that the hose can be neatly packed away any info would be greatly appr, thanks Stephen
sorry about the bad grammer

Unfortunately I think that you have taken the wrong approach. Compressors tend to draw a high current and having a mains one means that you will need to find an invertor capable to power it. Also invertors are a very inneficient way of powering equipment.

You would be far better off (and I suspect it would bee cheaper than your cheap compressor and invertor combo) just to go for a decent 12volt compressor like a Viair (around £135) in the first place.

As for the heat side of things, yes they do get hot and you will find that the cheaper ones will overheat quickly and require more time to cool down. You may find yours fine for pumping up one or two tyres in one session, but may struggle to pump up four large tyres.

When researching coompressors do check the duty cycle rating - there is quite a good basic guide to compressors at OffRoadRecovery.Com Air Compressor Basics - certainly enough to get you going.

After trawling through here, I think I'll have a go at plumbing in an old A/C compressor - I've been using T-Max jobby for the last three years, which I thought was worth a mention - small, very portable, about £50-£60 and inflates pretty quickly. All metal construction (it actually looks exactly the same as a Viair 400 - had it side by side with one once, only the stickers were different) and though it does get hot, it's never cut out.
I used it to inflate a king size airbed the other day and after only a few minutes returned to find it was about to burst!
It wasn't as quick to re-inflate four aired down tyres in the desert as the guys who were using on board engine driven compressors, but only a few minutes behind.
Be nice to shift the pump under the bonnet though, the T-max takes up the space of six large tins of , and in a 90 every little helps...
