Phil - what onboard compressor are you running ?

one of the new ARB ones.

cheers phil

where you have the 3/2 valve.

you can get those with a check vavle incorportated into them

Fitting an air drier is surprisingly simple and you can buy them with a pressure controlled unloader valve that will vent tank air out from the tank through the dessicant to atmosphere via the 3/2 valve and then when tank pressure drops to a certain point will stop the airflow.

If I understand you correctly the attached Rev 3 is what you’re suggesting. This way I get dry air in both systems – depending on what the Dessicant costs it could be worth it. Not much chance of freezing conditions in Western Australia though.

I have also included the manual valve that was recommended further down the thread.

On problem I have is that from what I see the Landy System runs at about 210PSI and to try find an onboard compressor that can truly deliver at this PSI is not easy. They state max 150PSI but when you drill into the detail they will only do about 100 – 120 PSI . The VIAIR Units are the same – state 200PSI but only really deliver about 150.

I suppose this is more than enough for my tyres, toys, tools, etc but while I am at it I may as well try getting a system to handle both. I may need to fit a regulator on the tyres, toys, tools outlet otherwise the kids bicycle tyres will get bloody big bloody fast .

Hi HarryO
Is there any reason you cant fit a LR compresor if you are finding it hard to find a onboard compresor for this amount of psi?

Hi Connock

From what I have read on the forums I do not think that the Landy Compressor can deliver the volume (litres per minute) to pump tyres, toys, etc. So I would have an initial burst of air which would then slow down to whatever the compressor can deliver. If it could deliver sufficient volume that would be the ideal solution because I would then have a 100% redundancy factor for the suspension. If I am wrong one of the guru’s please let me know.

As you most probably noticed this has grown over time and a lot of people would rather just carry a portable and fit the direct pump to each wheels airbag kit and be done with it. For me this is fun and I love adding these little “projects” to the Landy – it keeps me sane.

Cheers

Hi 400HPongas,
After your demo I'm treated myself to an early b'day present, LLams goes in over the weekend, the other disco is now back on the road as of tomorrow, engine done and running, time to start on the D3.......... Thanks for the insight.

Yours Marty

the dessicant comes in cartridges and cost about 20-300 bucks per cartridge. Look at truck shops for the filter heads and dessicant cartridges.

The only thing left that Id change is the position of the check valve and the tap. after a while and a few uses tap valves can develop leaks.

should work nicely and heres a kicker, you dont need to get to the full 210psi to get the suspension to work in an emergancy, 85psi is plenty but you have to have a manual switching setup to operate the suspension (I have a breakout box that I plug in in place of the ECU that gives me push button control of the valving.

Ive abuse tested a handfull of different pumps and surprisingly they will make more than 120PSI, I think 175 is the highest Ive seen without bypassing the thermal cutout system and running them on more than a good solid 13.5V It wouldnt do that pressure often but IMHO they'd do it often enough to keep you out of trouble.
