Best on board air, Tank or compressor?

Yes, but other compressors that draw 1/4 of the amps also only deliver 1/4 of the air output. The total battery draw to fill 4 tires will be the same in both cases, right?
 
I sure do like my Extremeaire. They make a 24V unit was well. Here it is in my LWB Samurai.

I'm fabbing mine from a reman York (10 CI) and a 4.5HP winch motor. The shafts will be connected with a modified spider coupling.

When complete, I expect this setup will produce about 8CFM @ 125PSI.

Should be the best of both worlds.

ive had the winch motor and the york in my garage for 5 years. please post pics of your coupling when you are done.
 
10 lbs Powertank on the FJ Cruiser rack, 20 lbs tank inside. I like running air tools and the nearly instant fills. I'm spoiled. A purist would say that the compressor is the only way to go and I can't argue. I used to do it that way and it worked fine.
 
Just got my 20lb CO2 tank appropriately regulated and hooked up. Had a chance to use it last weekend and I LOVE it! So fast and easy....:grinpimp:

I can't wait to use it with air tools. I was just filling tires and dusting, but with that kind of power I imagine it will spin some mad bolts too.
 
I love CO2!

...20lb bottles...usually I get through an entire wheeling season with about 15 trail runs filling up my 35's from 12 to 32psi..
One thing I would change is I would use a smaller tank in the 40, there just isn't a lot of places to mount a 20lb bottle in there.

So you are saying you can air up 60 35" tires on 1 20lb CO2 tank? I had a 20lb tank for a while and did not find anywhere near that number. I would say closer to half that. Wheeling for a weekend, 2 days. Airing up twice, sharing with 3-4 others... thats 2x5x4=40 tires... Maybe they were bigger than 35" and/or lower than 12lbs?

In any case... go with a (York) compressor if there is ANY chance you would be running out...sharing...unable to refill easily... It sucks to have to say no to a friend on the trail when they ask fo air (especially if it's in some emergency/breakdown situation out in the woods...)

Having used the 10lb CO2 for a while now, I couldn't be happier. It's saved my bacon a few times. Including when I got a nail in my tire and was almost late for work, but was able to pull over and fill up in about 2 minutes from almost a complete flat. Airing down is actually the much bigger pain now.

But I would definately recommend some kind of electric compressor or back up of some kind. I plan to use my ARB compressor that powers my lockers as my back up in emergencies if the C02 runs out.
 
So in the interest of some sort of scientific perspective on this I asked out on the LCML for input. A couple of "science guys" did some higher level chemistry mojo (details available) and came to the conclusion that a 20lb CO2 tank could fill ABOUT twenty 35" tires from 12 to 35psi. In ideal conditions (never really gonna happen) maybe that number could be 30.

So... as they say: "I fart in your general direction" to those of you in the CO2 camp! Get a compressor and be good forever. ALSO get a CO2 tank if you want faster fills and a portable fill/air tool source (both very good things) but don't think it's always gonna be there for you.

(now, lest somebody takes offense to my "fart" comment: relax. I love you all... I said that for it's comic effect, not to insult anyone or anything. No real people or products were harmed in the making of this no-so-humble opinion)

I have run a 10lb CO2 tank in the 40 for about 5 years now. I have found that a full tank with no sharing or other use will air up my 35" MTR's from 12psi to 28psi 4 times plus two tires left in the tank. I like the fact that I can fill up rapidly and seat beads if needed. That said... I HATE the fact that it costs me $15 to refill the tank each time I need a fill. I also hate that on my 5th trip out I need to dump two tires worth of CO2 into the atmosphere or use it frivolously somewhere around the house so that I have an empty tank when I go to get a fill. It is because of this that I am installing a York and a small 2 gallon tank in the 60 for my air needs. I will also be doing this on the 40 eventually and the CO2 will be relegated to portable air duties around the house or camp as required.

The total cost of my CO2 setup was $135 used from a friend. You could probably piece one together off the net for around the same price. My total investment in the York setup on the 60 will be right in the same neighborhood and It won't cost me an extra $15 every 5th trip out on the trail. For me, the math alone leans towards the York as the long term answer. Just my 2 centavos though.
 
So, in light of attempting to fill the void in my engine bay that my dead, and removed, smog pump has produced, could one fit a York compressor under there? It seems like a nice, out of the way place to put it. I really like the idea of a consistently running air pump.

Also, what would determine which vehicles had the 10 cfm york AC pumps as opposed to the two smaller versions?

1. I have a used 210 York I could sell you... contact me if interested.

2. I looked at fitting a York into the smog pump locationon my 85FJ60. I do not THINK it'll fit... I will be pulling off the intake/exhaust sometime soon (and the PS pump) and will be able to give it a better look. I WAS thinking of either the PS pump down there or a second alternator to use for an onboard welder/AC source. If I move the PS pump there I'd possibly put the York up top.

I'd like to hear more about this reconfig if others have done it...

I don't have a 2F FJ60 so I don't know how different my '79 FJ40's engine bays is organized. That said, here are some pics from the '79 FJ40's 2F engine bay. I think Mudrak makes and sells the adapter. It works great (on the 40).

When I convert the 3FE to a 2FE I am going to take a better look and see if it's possible for me. Would love not to haul the 20lb CO2 bottle around.

Problem with the York on a 60 is the hood... not as much room above the engine on the 60, the top hits the hood... with my 2" body lift that should no lnger be an issue... now it's just a matter of getting the time to get all the other things done so I will have time for the York install...
 
The soon to be released Warn compressors sound very nice in the specs... especially the VTC ($720). 8CFM at 90 psi and includes a one gallon reservoir.
 
I'd go for a dedicated compressor. If you're really out in the sticks and need to use that air for other things, forget the bottle. I mean, if it's for an expedition wheeler, what would you do go down and get a refill?

If the Warn Plant decides to s*** itself ,you will have no winch and no compressor.
If you have tanks then you need a compressor to replenish them.

I have a very sturdy Bushranger Maxair compressor which can pump up a large tyre from 17 to 35PSI in 2 1/2 mins and reportedly do 20 tyres in independant testing.
It takes up the room of a shoe box and weighs 4kg.

I wouldn't even install a compressor in the engine bay,it restricts airflow and is a PITA if you have to fix something

Everything on a true expedition rig runs on the KISS principle. Flashy gimmicks are for mall cruisers;)

My solution to this problem was to mash an Extremeair compressor with a 3 gallon craftsman compressor to make a 3 gallon 125psi 12VDC unit.

ExtremeAire Craftsman Mod - IH8MUD.com Forum

I like that I can put it in any of my vehicles. Not quite the same cool factor as a built-in onboard air option though.

YMMV

actually there are advantages to not having a built in unit.... but probably not for arb lockers.

i really dig the idea of that sears compressor!

well done.

Thank you. If you're interested in this kind of setup, read the thread that I linked to. I didn't use the sears compressor, just all the stuff it came with. I already had the ExtremeAir compressor, so this made it more usable. There is a company making a 'Puma' unit that is a similar result and less money if you don't already have the ExtremeAir.

I have used my Extreme Aire for a little while and I am pretty happy with it. It was pretty easy to install with the airbrake hose and push-to-connect fittings from ExtremeAire. I have two Warn 2.5 gal (hotdog) tanks mounted on my roof rack. It's enough reserve to run my 3/8" impact wrench without fail.
