Outer Limits 4x4 Board

I am trying to find the best air conditioning compressor to mount under the bonnet to use as a air compressor. I have heard that some have their own oil reservoir for lubrication and are better suited for this.

Is anyone running one and what vehicle make and model is it from.

chrysler sigma Sanden 508 air con compressor.
if your lucky, it may have been discussed prior to today..

google works too

is the factory compressor from an XE falcon useable? i only ask because i have one floating around

Thanks Bogged

Ran a search and found this has been discussed a few times before, the 508 seems to be the pick of the compressors for this use. Will visit the local wreckers and see what I can find. All I Have to do then is find the room under the bonnet of the GU.

The ex falcom pump is bulkyand requires a trick mounting. It also needs pulling down cleaning out and sme sewing machine oil or similar thin oil as a lubricant in its built in sump. Have heard they burn out oall the same but have been running mine from a 240 volt washing machine motor for about a year now as home compressor, still going strong, dont know about the angle stuff tho it might not like getting tipped over too far.
As for the other pump mentioned dont forget that air con runs liquid so you have to substitute that liqid with anther lubricant, have been told to put in molly grease but not sure where to put it. Hope my scant knowledge has helped. if anbody can add please do i would like to know too.

You just out an grease nipple in side of case body and pump in Moly every now and then.
My Endless air has been on 2 Nissans, petrol and Diesel (Mavs) and is still going strong after 6 years and lots of pumping.
You must use the orig A/C lines for output to take the heat of the compressed air.

How did ya setup the home compressor like that? Using a tank?

cheers

just wondered how this works as an air compressor as i am keen for this..

Could i use the A/C compressor thats already in my MQ patrol?? i don't want A/C so i would love to know what needs to be done and if i can..

Cheers stewie.

Sandens blow oil.

Geniune Endless Air's have been modified to use grease instead of oil and to stop the recirculation of grease/oil. How? I wish I knew.

And before anyone pipes up and says their Sanden doesn't blow oil, well like any good Rover, "If it ain't leaking, there is no oil left in it"!

Don't get me wrong, these things pump hard and FAST! but the oil drives me bananas.

So before you go to the trouble of fitting one of these, be aware that it is a major issue that you'll need to address.

Endless Airs still blow grease!

Look at http://www.onboardair.com/

this will give you good info to go on.

If you ran a tank with a filter would this help at all (to catch the oil) ?? If you used a truck air brake tank you could use the relief valve\water getter outer (Technical term ) to remove the oil from the tank ... would stop the tank rusting up as well ..

This is one of the ways to address this but the tank has to be in-line before anything else (obviously) but when pumping hard they tend to vapourise the oil so it will still be suspended in the air in the tank when it goes out the other side. This can be further addressed with a moisture trap but these are still not 100% (as I have found in 2 installs).

You need to top the compressor up with oil regularly otherwise it won't last long so in essence, there are things you can do but you will never completely get rid of it.

The decision is up to the individual as to whether they can live with it or not. Personally I can't and will be installing a high flow 12v compressor for my on board duties.

Cheers.

Thanks for that ..
Has anyone tried the big mo-fo compressors that the custom air suspension crowd use (about 50cm long, rated at 150 psi constant duty) would pull quite a few amps, but would be quick.

I have this system...modded 508 to grease, and a water trap after the pump to catch the grease...being the budding servicer i am, i over luv it and catch whats got past to reuse/recycle on my driveshafts :-)

We have a York compressor from Kilby (www.onboardair.com), the unit I got was new - but it's still basically an air consitioning pump.....
IMHO whilst the york (falcon/volvo/valiant) is bulkier than the sandan it does put out more volume - but you need to be aware that there are 3 different sizes of York.
The sandan is very good - but I wanted to pure volume of the york for the airbags - and they really do work bloody great..
We have an oil filter & return to the pump - but you still get a bit oil blown out - fact is it's just the nature of the beast.

All I will really add is there is NO WAY I'd consider a 12v after enjoying the benefits of engine driven.

Hey Wooders, How much did the york set you back?

The york with all the mounting to suit a Jeep Wrangler whilst retaining the A/C (yeah I went the lazy kit option)...$950....but was a simple bolt up and with 9cid it cranks the air out

I like Lazy Did you import it yourself or buy it local? Might see if they hve one to suit a Small Block Chev...

Wooders Garage is the Aussie Distributor for Kilby

So how much for a SBC Kit then?

I would think an old York 210, like Wooders suggested, or a twin cylinder Tecumseh HG 1000 (cast iron bore) would be the go.
Give either Kirby Refrigeration or Lovelocks a call.
A swashplate design like a Sanden isn't a real good idea as an air compressor, as some of you have found out.
Any refrigeration/air conditioning compressor is going to pump oil, but the old twin cylinder jobs are revving much more slowly and don't tend to lift as much oil out of the sump.

I've had no major problems with the Sanden 508/tank system I have set up in the Rocky. The system took a few tries to sort out the way I wanted, and to do what I wanted it to do. Its been fitted for about 6 years. And yes, theres no way I'd go back to a 12V compressor. In fact, last year I won a new ARB compressor kit complete, and sold it cause I didnt want it.
