that write up is pretty good, do u have the link to it? i want to check out the pics.

i want to put an endless air system on my next 4b when i get it.

Instead of using a nipple for lubrication
You can get a inline oil dispenser That screws into the air intake hose or the hole
As the air gets drawn in the dispenser sends oil with the air to lubricate the pistons inside the compressor

Grease nipple idea is a seized compressor waiting to happen.

Why do you say that? If the piston type run a sump that separates the lube from the charge air why would it cease? It's effectively doing what it was designed to do I would have thought. The original SD piston type compressors weren't libricated byt the AC gas as is now the standard.

I've had a endless air setup on my Suzuki sierra that proved to be unsuccessful with the use of the factory denso (vane type) can't be lubricated correctly in an endless air setup causing the compressor to seize, I had pretty much given up on this setup for the time being and started using an electric compressor. After a little more reading online I discovered that the compressor that is more suited to this application is a saden a/c compressor as they use several pistons in there compressor and not vanes. This system can be lubricated by fitting a grease nipple to the casing of the compressor to keep the internal mechanisms well lubricated. I found the following compressor many moons ago at the local Suzuki wreckers. It was marked as being a vitara compressor, but Unfornatully it isn't a direct swap with the denso's mounting brackets as the saden compressor is a slightly larger diameter casing and the pulley offset is also different. But the good points are that it also runs a 4-PK flat as the old one, Also the saden's compressor pulley diameter is smaller than the denso compressor which would mean that it would produce more volume of air at a lower RPM. Now here lies the question, does anybody recognise the compressor above as I would like to find the correct mounting brackets so they don't have to be fabricated. I'm keen to see if it will work.

Okay then, I just seen it on a endless air setup one day when I was searching for endless air setup for the zook Not sure how it worked, I just assumed it let's a certain amount of oil in at a time. But your right, not sure how it would clean the oil out of the discharge air

Looks like it says SDB-705. See link here http://www.erareplicas.com/gtman/ac/sanden.pdf I don't see a 705 but the SD does mean it is piston driven which is what you want. The 5 should be the displacement so it flows a bit less than the SD-508 which is the one usually recommended. It doesn't look like it has the same sump as the SD-508 either but I'm assuming as its a piston one it does have a similar design (or maybe its on the other side of the compressot in your photo). Don't use an in line oiler. The benefit of those piston type sandens is that you can run oil/grease in the sump as mentioned in the thread you posted. What vitara was it off? I've been chasing an SD-508 but if I cant get one with a 4pk belt off a vitara that would be great. Wonder if the sacrifice of the 3 cubic inches of the displacement over the SD508 is worth it though.

This should work OK as long as the lubricator used has oil capacity and air flow large enough (but not too large) for the compressor, they work on a venturi effect so any passing air will draw lubricant through so long as the lubricator is installed the right way and not so large that it wont venturi. Plenty of wall mount type units available as well as tool oiler types, we regularly install these type of unit (usually filter/regulators) in to shovels, draglines etc so vibration will not be an issue. Grease nipple idea is a seized compressor waiting to happen. Plenty of lubricator options available http://www.wilkersoncorp.com/products/lubricators.shtml L01 is a tool size lubricator ideal for this but only holds 7cmSQ of oil L03> nearly all have a drip feed set up so could also be used. A particulate filter would be required to remove the oil before it hits the locker etc.

I have said bracket to mount a sanden compresser onto a G16 without power steer, had to replace it with a power steer version, when I got the bracket 4 years ago it was the last one of either as the company stopped making them (TRX Automotive) Ill sell it for the right price From my reading the compressor has an internal sump that lubes everything as well as oil in the line for other stuff, so might jsut work with oil in it

The compressor takes in the lubricant and spits it back out with the compressed air, a grease nipple can only supply a small amount and has to be manually filled, a lubricator will continue to feed the compressor as long as it is running with little manual interaction. As I understand it, an automotive air con compressor gets its lubricant from its own sealed gas system, the system described in this thread system is not and can not be sealed. I may have missed something if so please tell me.

Endless air don't use oilers, only the grease nipple and mods as described above and they run for years, with occasional greasing. I've played with an oiler but I wasn't satisfied it's a useable solution for this application - the grease nipple mod has the runs on the board as far as I am concerned - the two cars I've been involved with with Endless air setups have run for years, trouble free.

Hi Squiz, There are a few different types of AC compressor. The SD compressors can operate with merely oil (or grease with the additional of a nippler) in the sump with a small modification. Refer to the 4th paragraph and photos in the link below. This is the link that oosuk pulled his info from to start with. There may be some oil that bypasses the pistons I guess but it wouldn't be a huge amount. http://www.grungle.com/endlessair.html EDIT: Beaten by Steve

so what type of compressor is in a 1992 LWB vitara. could it be used for a endless air set up?

Hey Steve, My brother did a write up half way down this page http://www.4wdaction.com.au/forum/viewt ... &start=125 He fitted endless air to his v6 rodeo, which used the piston style sanden pump. Hope this helps.

It's most likely a Denso - Vane type that can't be used. Steve.

All you need is an oil trap, like the moisture traps big compressed air systems have... and then feed the line back into the compressor, with a hand valve, and just keep an eye on the oil trap, once it gets to a certain level, open up the hand valve, and it goes back into the compressor... this could be set up to do it automatically if needed, but would complicate a simple setup...
