Hello all
I have SLS on my Disco 2 and the compressor got wet and now not working. I have read some of the forums about upgrading the compressor to a ARB compressor.
But I have some other questions and see if any one has done other upgrades.
Has anyone used the AOB (air on board) compressors? Are they any good ? Also does anyone know the pressure rating of the original valves in the SLS valve block?
Has any one done the upgrade and installed a air tank into the line? So the compressor does not have to run as much.
The compressor I am looking at has a auto start and shut of valve. Operation pressures 120psi on and 150psi off. Is this too higher pressures for the valve block and should I put a pressure reducer in the circuit? I am also setting the system up to inflate my tires.
Thank you guys for any help and advise

I'm keen to know this too.
I'm going to be restoring the SLS in my Disco. Every thing is in place except the bags and I have no idea wether everything is working. If the compressor has had the possum I won't be using a genuine one, something after market. I thought it would be a good idea to use a small gas bottle mounted under the vehicle for the tank.
Happy days.

Thanks zzsteve
But this does not answer my questions. I had already read this article. That's where I got the idea for upgrading the compressor.
But I am asking about a air tank in the system and if the valve block would handle the pressure of this 120-150psi??
think from memory the ARB air compressors are around 100-129 psi. just remember these compressors have not been designed to fill tanks, i have a friend who has 2x 90lt tanks and the air lines keep on melting due to the heat in the air

I am going to work all this out very soon. i am going to add SLS in my TD5 Ute conversion. I will be running a 2nd A/C as a pump.Originally Posted by travellerpaul

So is there a problem if the tanks are filled at the servo and then the ARB compressor just used to keep them toped up? The tank would fill the bags really quick and then the compressor should take no longer to top up the tank than it would to fill the bag by itself. The same amount of air will be used either way. The tank is just used as a buffer. The problem might be that the bag would be being filled at a low pressure where the tank will always be over 120psi.

shouldnt be a problen filling the tanks from a compressor, im looking at this and my friend with the twin tanks can as well. its the extended running time with the arb compressor where the heat come from

You'll need a regulator from the tank probably depending on the running pressure of the SLS system. I'd run hard lines, at 150psi copper would do but 6x1 steel hyd tube is very cheap and bends very well by comparison. Also easy to add fittings.
Tank wise 150PSI won't give much storage on a pressure vs volume basis so the tank would need to be quite large. An option would be to fill from a higher pressure source (as long as the tank was rated for it) and add a check valve on the tank inlet before the reg so the compressor wouldn't see high pressure and blow up until the tank pressure dropped below the pressure capable of the compressor and allowed flow from the compressor to the tank. You'd also need to pressure switch the tank for the compressor otherwise the compressor would just deadhead cycle against the tank pressure holding the check valve closed if there was any pressure drop in the line from the compressor to the tank.
