I am in the middle of my build and one of the next things to consider is air on the trail. I built a rear bumper from 3X6 square tube that I plan to use as a tank and I have found all sorts of gauges and crap but the compressors range from $40-$400 and I just want to see what you guys are running and where you mounted them. I don't plan on using air tools on the trail but I would like to air up or fill a flat. I plan on running 35s.

You can rig up a york. junk yard cost is like 20 bucks. You can run a electric. I have a viair 450c its a 100% duty cycle, 105 off and 150 pressure switch.

crawlerdad · « **Reply #2 on:** Nov 08, 2009, 08:33:27 PM »

I would like to stick with electric.

junya92toy · « **Reply #3 on:** Nov 08, 2009, 08:57:30 PM »

My 450 was like 275, its one of the best you can get for the money. It only pulls 19 amps at full load too.

crawlerdad · « **Reply #4 on:** Nov 08, 2009, 09:08:57 PM »

What size tires do you run, do you have a tank, and how long does it take for you to air up? If I run a York do I have to get rid of my AC or anything?

junya92toy · « **Reply #5 on:** Nov 08, 2009, 09:26:50 PM »

35s its not super fast but its not super low either. I have 2.5 gal tank. If you make a custom bracket, you can keep your ac. my setup is like 1 cfh, a york is like 6+ cfh

Oasis compressors are crazy sick

junya92toy · « **Reply #7 on:** Nov 08, 2009, 09:45:14 PM »

they are a york hooked up to a winch motor.

PhantomD aka Zach · « **Reply #8 on:** Nov 08, 2009, 10:46:31 PM »

it's a modified starter motor, not a winch motor. I have a friend that tried to make his own with a winch motor, it pulled WAY too many amps.

I had a york on my jeep AND the stock air conditioner compressor, it was AWESOME!

having just the york was plenty... I could fill up my tires and my two friends rigs in less then 15 minutes... probably more like 10... it did not take that long.

I don't know how readily available they are, but I run a Thomas compressor out of a Hummer with CTIS. I got 3 of them for free because they were a recall item for some reason so the dealerships removed them in good working order and replaced them. The issue was a wire that would come loose inside. It flows enough air that I don't run a tank. Fills a 35 in less than 2 minutes. !00% duty cycle. Maybe a guy could find a deal

I have a Chevy 4.3 so it was just natural to modify the AC compressor for OBA.

What about Extreme Aire? have heard good things about them, they sure are pricey though....

crawlerdad · « **Reply #12 on:** Nov 09, 2009, 08:03:11 PM »

So far I think the Viair is winning due to budget and that I'm not sure I want to stuff a york under the hood. I know more about the electric compressor so it would be easier for me to set up. I was hoping someone had an idea on the cheap side.

88_Pathy · « **Reply #13 on:** Nov 09, 2009, 11:51:44 PM »

Viairs are pitiful with anything over a 33. A budget co2 setup would be far better.

86rustbucket · « **Reply #14 on:** Nov 10, 2009, 12:44:54 AM »

yep 88 pathy is right heres my budget co2 setup

the regulator was $35 at poly performance
the fittings were $5 at harbor freight
the tank i borrowed that will be the main part to find but even if you pay 50 for one you got a $100 powertank

junya92toy · « **Reply #15 on:** Nov 10, 2009, 06:42:05 AM »

Co2 runs out, viair never will. It maybe a little slow but its got no limits.

crawlerdad · « **Reply #16 on:** Nov 10, 2009, 07:08:48 AM »

I like that idea. I could buy a $40 compressor as a back up with the money saved. I want to look into viair a little more before I start building.

88_Pathy · « **Reply #17 on:** Nov 10, 2009, 08:18:23 AM »

My cheapo mv500 electric pump is my back up, it can be had at pep boys or costco sometimes. I paid like 60$ for mine at 4 wheel parts. It is faster than the viair pumps but will overheat if I do more than 4 37s. My c02 setup will do 4 trips airing up from 8-30 in lees than 1 minute per tire. Then I have to help my buddies out because they are still on the first tire. I would love to have a OBA setup but york or oasis is the only way I would ever switch. Everything else is just too slow.

Is that a scuba tank? Where do you take it to get it filled? What does it cost to fill it?

junya92toy · « **Reply #19 on:** Nov 10, 2009, 08:06:43 PM »

Its a co2, even a 3000psi air tank cant come close to the volume it can hold. But once its empty, you have to exchange it at a welding supply store.

86rustbucket · « **Reply #20 on:** Nov 10, 2009, 08:25:34 PM »

its a c02 tank for a soda machine

its like having a powertank without paying $450 bucks for it

marlin charges a $1 a pound for co2 that is a 20 pound tank

good luck putting a bead back on a rim with one of them rinky dink compressors

junya92toy · « **Reply #21 on:** Nov 10, 2009, 08:31:28 PM »

Ive put plenty of beads on the rim with my rinky compressor. You just have to know what youre doing

86rustbucket · « **Reply #22 on:** Nov 10, 2009, 08:34:47 PM »

yeah your junks probably bigger than mine too

86rustbucket · « **Reply #23 on:** Nov 10, 2009, 08:35:56 PM »

i know how to use a peice of junk compressor i am just not in denial about the fact that they suck

junya92toy · « **Reply #24 on:** Nov 10, 2009, 08:37:44 PM »

Hey I never said it was fast but its far from junk.
It works every time.
I can run air tools.
It never runs out.
It doesnt cost any money after buying it.

86rustbucket · « **Reply #25 on:** Nov 10, 2009, 08:43:54 PM »

how rinky is your compressor though?
the only one i used seem to take forever to take a 33 from 15 to 30 psi
i ended up just driving on 15 psi to the gas station

i know there are bad a ss 100% duty cycle viairs but they arent cheap

i throught this together for under $50 bucks

junya92toy · « **Reply #26 on:** Nov 10, 2009, 08:46:41 PM »

I have a viair 450c with a 2.5 gallon tank.

86rustbucket · « **Reply #27 on:** Nov 10, 2009, 08:49:46 PM »

msrp is $300

junya92toy · « **Reply #28 on:** Nov 10, 2009, 08:52:34 PM »

Ya I got mine for 275 I think. But think about it. How many fills will it take with the co2 before you hit 300$? What if its got a leak, you leave it on and it empties?

86rustbucket · « **Reply #29 on:** Nov 10, 2009, 09:02:12 PM »

well considring i get to go wheeling maybe twice a year
and 20 pounds is $20 from marlin that would be fifteen fills for $300
now lets say i blow a whole tank every trip
i think that would put the year around 2017 once im finally $300 dollars in

im not sayin its junk but if you got the money go for it, if you want the same results for a fraction of the cost do it my way
