On board air

[Rover Nick]

Srry if this has been asked a million times, but what is the best option for on board air. How is the ARB? How does the arb work? What are other good options in on-board air. I do have an EAS classic the has been converted but I'm not sure about plumbing the eas because I have heard that the whole system might just crap out. What are your thoughts?

i have an arb air pump and its super sloooww........... i got it for dirt cheap so it doesnt matter so much. if youre looking for pumping up tires, get something like a powertank. those things are fast!

a 20lb aluminum scuba tank with a high flow regulator. Cost like $20 to fill up $40 to certify a year and about $250 for the hardware new. But will fill up about 15 sets of 44's before needing a refill. Will do a 44 in less than minute I heard. 3000psi is alot of air!

Nic, i love you, i htink my dad still has his from the 80s....

Nick, what do you want to do with the air. I run an airconditioning compressor connected to a 21 litre tank. With the car at idle, it will pump up the tyres around the same speed as a Service Station. Take it up to 2,000 rpm and it will run any air tools.

ive been thinking bout doing this...
a good way to get the parts for cheap is try craigslist... look for a tank which has a current hydro and visual... and another thing u need is a 1st stage. and some misc hozeswhich u can get any dive shop..
there is also some dive sompany that makes the attachment for schreder valve...

Sounds like your tank was super charged. A full CO2 bottle will fill lots of tires but not 44"ers in under a minute.
Don't go waisting to much money buying a used tank unless you have a local supplier of CO2 verify they will fill the tank. If the tank doesn't have the proper stampings it is only good for a paper wate.
If you buy a new set up, spend the extra and get the larher bottles, they are not that much more, only a couple dollars more to fill and last alot longer especially if you want to run some power tools .

I saw this link posted on Dweb, seems like a really clean and economical way to install air on a Disco

I'd like to do an on-board air compressor but a powertank won't work because the nearest fill station i know of is 2 hours away. I have seen someone build a big storage comparement in the back of their LR3 with an ARb fridge and a compressor set-up. How much do you think it would roughly cost to make a complete working system with a tank and compressor.

If you only want the air to pump up tyres, and your not running large tyres, there are a number of 12 volt compressors under $100 that will work well. If you run 33 inch tyres or larger, you would serious look at an on-board tank with engine mounted compressor.

The superflow mv-50 air compressor that is used in that writeup above is great. I'll eventually be doing an air tank in conjunction to it, but just for airing up tires it's fast and cheap.

How would you go about powering a conventional compressor?
