On-board Air setup

[AceMan]

Myyoung, that is a very nice setup. I saw your thread at DT, too. I just didn't get a chance to respond. That will definitely come in handy on more than one occassion.

We should probably put this in the Members Build section. What do you think?

[TwinStick]

LOL, I will probably NEVER have the money for that one !!! I definately DO NOT have it like that. Wish i did. For now, my cheap ass Harbor freight inverter setup & my cheap ass Craftsman compressor works just fine for me. It certainly is nice to be able to air up by yourself. Your set up is SOOOO clean & neat. Kudo's to you sir !!!

Thanks guys! This ended up costing a little more than I was expecting after buying all the miscellaneous fittings and the $26 bottle of Loctite 545, but it was still about the same cost as the Power Tank I was considering. I'm somewhere around $525-550. All in all, I'm extremely happy with the system.

I just went out and drained one tire down to 25 psi and filled it back up to 50 psi. Fill time to around 45 was about 2.5 minutes and the last 5 psi took another minute. 45 psi would be an acceptable streetable pressure (I run 50 up front ad 45 in back) and I could do all 4 tires in about 15 minutes. Not too bad!

Awesome set up!

I just picked up the 400's today. Going to try a set up like yours. Looks mint

[jeep_boy02]

I've been looking into the viair super duty system. Can be found under $400. Not too shabby for a 100% duty cycle that includes all hook ups and such.

I'm diddling around with a small OBA installation on the Tundra, using a single cylinder ARB compressor, 3.08 cfm free air flow without a tank. So, I'm looking for a small tank. In the process I ran across some new OBA hardware from Kleinn, the airhorn company. They told me that their 7275 and 7350 were intended specifically for OBA rather than for the airhorn market. They are self-contained and ready to bolt into place. The 7275 is 50% duty cycle and the 7350 is 100% duty cycle, and they are about two weeks away from actually shipping units. Both are already listed on Amazon (just search for Kleinn with those model numbers) and are shown as "temporarily out of stock." Kleinn told me that Amazon will leave it that way until they get their first order and then they will become stock items.

Finally got mine wired up and plumbed inside a tool chest

[Mr.Smith]

How's the heat inside there?

[Kenadian]

As far as I know not bad cause it pulls in cool air from the intakes mounted outside and it fills the tank in 45 seconds. So not a long run time

[Mr.Smith]

Hahaha! I imagine it's not too big of a concern up north.

[Kenadian]

Haha yeah it doesnt get overly hot. I'm sure if it was on a heavy cycle like an impact be tougher on it

Some of the air systems on this thread seem to have a lot of work put into them, for minimal air output. Most of those Vi-air compressors are only putting out something like 1.8 cfm, so even two of them plumbed into an air tank takes a long time to fill up a set of tires. Didn't I read 15 min on an earlier post? And that Kleinn 7350 compressor that was mentioned above is downright puny. It only puts out 1.3 cfm.

Here is another alternative to consider. For the last three years I've been using one of these Smittybilt portable air compressors.



I have one in my motorhome, and another than I can move back and forth between the truck and the Jeep. I've used it pretty much every weekend for three years, and no problems with it at all. And with an output of 5.65 cfm it fills up 4 tires faster than 15 mins. It has a continuous run time of 40 minutes, and it cost $149.

Re the Kleinn 7350 reference, note that I said I was working on a SMALL OBA system. Not willing to give up the back seat or an entire tool box in the bed of that truck.

Re the SmittyBilt portable compressor you referenced, the OP said:

I don't really want to deal with portable compressors either, I like the idea of having the compressor and tank mounted under the truck and out of the way.

[Kenadian]

I found with the high out put Smittybilt which I have also. That it would heat up to much and blow the rubber line off multiple times

[MoparToYou]

They do get warm, but I've never had the hose blow off. All of these small compressors get really warm when filling four tires. If you're mounting your compressor under the seat, or anyplace that might be sensitive to heat, be very careful. You don't want to cause a fire from compressors that become way too hot to touch.

I like the Smittybilt though, because it is cheap and fast. There have been times when I have filled all four of the 37" tires on my Jeep, and then filled two of the 35" tires on my friends Jeep, before he had filled two of his tires with his Vi-air.

Two compressors that I am most interested in are the Warn medium duty compressor that puts out 12 CFM, that was mentioned earlier in this thread, and the ARB twin air compressor that puts out 6 CFM. They no longer sell the Warn compressor. Does anyone know if the Warn is sold under a different brand name, or if there are any vendors that still have the Warn compressor in stock? And finally, has anyone mounted an ARB twin air compressor under the hood of a Ram with a 6.4?

I have the Warn hardmounted in my truck (the white 3G in the earlier pic). It's a great compressor and I have been on the lookout for another one, just because. But I have not seen one for sale in a long time. Worth looking for, and the only thing I'd rather have is an Oasis, if it would fit. I'm not willing to give up cargo space for things like compressors and tanks and batteries and inverters, so the Warn was perfect for my situation.

[MoparToYou]

Thanks for mentioning the Oasis compressor, it looks interesting. 15 CFM would get the job done, especially with a 100% duty cycle. It weighs 65 lbs, though, and is 21" long. Wonder if it would fit along the frame rail?

[Ducky's Dad]

Wonder if it would fit along the frame rail?

Should fit. My measurements indicated that an Oasis 3000 might fit behind the grill on my 3G, but very tight fit, if at all. Problem on the 3G is the hood release mechanism getting in the way, but the 4G does not have that problem. There are several OBA threads on Expedition Portal, worth reviewing.
