Looks to be an engine driven one but can't say I've ever seen one of these before.

Very Cooool

I remember seeing these in a 4WD magazine quite a few (15+?) years ago. From memory the Australian Army were looking at them, the biggest hassle is disconnecting from the engine when not in use. They were geared to run efficiently at (or near) engine idle speed, and would suffer significant damage if run at "normal" engine speeds.

From memory, performance was significantly better than any of the 12V compressors available at the time (as you'd expect), but I don't know if pumps like the Twin Tongue were around back then.

These days I'd be looking at a modified AC compressor.

Cheers,

Scott

You'd thing that they would have a clutch on the front of them !

These things are still fitted to the 6x6 landrovers that we use they are a pretty compact sort of setup and seem to work well. Never looked at putting one on my 4b though.

Cheers

these are from the army rigs

they hav a max of 1200 rpm anything over that they self destruct

but put out around about 5 cfm at 1200

bloke next door has one or to i think just never got round to setting it up

Magnum engine driven air compressor used a manual clutch for freewheeling when required, but an electric clutch was also available. YOu'd have to lift the bonnet to disengage it. They worked very well and came out around the same time people were just starting to use air con comps for pumps. V design can make fitting difficult..

I have an engine driven compressor in my Series 3 SWB - they are modified AC compressors,cost about $300 and are not rare in Melbourne. Fitting them can be tricky - expensive - it is often cheaper to get someone who is good at that sort of thing to make up brackets rather than but them.
The company that 'makes' them is called Endless Air and they advertise in 4WD magazines but if you want contact dtails email me and I will lok them up in the telephone book.

The army style compressors work well. There is a small stud on the pulley wheel that pushes in to engage and pulls out to disengage, obviously while the motor is off. A quick hit on the accelerator pedal usually disengages it too. I have never seen them on anything before except my 6x6 at work.

Hi
These are good but easily damaged and light duty...unless you have spares, it would be better to go the air conditioning compresser way....

From what I have seen, the Endless air is just a used A/C compressor painted, tapped and fitted with a grease nipple. Much cheaper to go to the wreckers and pick one up

Ive done just that...been pumping tyres for 2 years now no problems.
The good part about endless.is their brackets ready made.

i had one of thos compressors setup on a mq patrol deisel.. had a clutch that u had to engage or disengage manually.. wasnt self oiling, u had to put oil down the air outlet to lube..worked real well though. sold with the vehical. i custom made mounting brackets to suit.

i have access to a coulple of these and will try to set one up on my zook

it will be operated by electric clutch and will be connected to to switches

the first will be a pressure switch

the second will be a swith that cuts out over 1200 rpm

and will see how it goes basically just have to stop and let the car idol and than you would have 5.5 cfm which can run rattle guns and wat not

if i get this set up and sorted may be selling it as a kit which all you will need is some custom brackets for mounting and belt
