On Board Air Questions

If the CFM of the compressor doesn't match that of the horn, then you'll need a tank. Can't really say yes or no until we know all the facts.

And also, the compressor doesn't store much air so even if the CFM is high enough, it can't sustain you staying on the horn for long. I'd just plan on getting a tank to be safe. They're not much money by themselves.

Ok but is that compressor a good one for running the tank for the horn and then some lockers maybe

if your running a 2 gallon tank then yes it will be fine. if you get the twin which is 100% duty cycle you shouldnt need a tank at all or just a smaller tank

Yeah that's fine. If you want to air up your tires you might be waiting a little while. That's where the dual compressor shines.

the two gallon tank will help midigate the time it takes to air up due to the tank pressure. he may even be able to run air tools off of it. since the single has a lower duty cycle it only needs to run long enough to fully pressurize the tank.

A two gallon tank isn't that big. I don't know what size tires the OP is running, but a 2 gal will not take care of 4 35's on a single "charge". I can't speak to how long that compressor would take to fill a 2 gal tank (may be on ARB's website), but I'd bet a twin compressor could fill 4 tires faster than a single compressor and 2 gal tank.

i think it will do just fine. my guy who works on my jeep and does my welding runs the cheapest vlair and a 2 gallon tank in the back of his bagged cars and trucks. he is able to fill up the bags and run air tools off of that set up. the compressor cycles on and off when the tank pressure gets down to 100 psi i think he said. the tanks compacity is 140 psi.

Ok well right now, money is limited and unless anybody has a dual used they can find me or one I can get for cheap, I'm going to have to wait the extra time waiting on just the single compressor and the 2 gallon tank,
The compressor is 35% duty cycle. Not sure what that will do me in regards to being able to air up, but the site doesn't say how long to take for airing up 35"s
 
Steve and I got slightly off topic, but I was just warning you that if you're looking to use this setup to air up your tires, it's going to take awhile. This little compressor is only pushing 0.47 CFM @ 29psi and that's at a 35% duty cycle. In other words, if you ask too much of it, you are going to overwork it and will need to wait between runs for it to cool down. You may not be able to do more than one tire at a time.

If funds are an issue or your needs don't include such high volume demands as filling up 4 large tires, then no worries. We were just trying to provide some insight in case you were interested.

agreed yes we did get a little off topic but good info (i believe) was flowing thru us both to try and help with running a good set up.

as dave said the compressor will take a long time to fill up 4 tires on its on. thru a tank it will prob make that time a little less. the best possible option is to run the arb twin (or something like it) or get a warn powerplant. these will help ten fold.

Ok well I'm probably not going to be airing up more than one tire at once right now. And when I eventually start to move into more rock crawling and harder trails where I would really need a winch,I'll invest in the PowerPlant and then just use the compressor for lockers and the air horn. For now it's just going to be the tank with the compressor, unless anybody can find me a slightly used better compressor or even a used double compressor.
Thanks again for all the help

well we are not saying its going to be for more than one tire at once. we are saying its going to take 3-4 mins prob for each tire to fill it up and thats just for a 35" tire. i can fill up one of my tires in just over a min. i fill up all 4 in just over 6 mins.

I am not too worried about that, I am not getting beadlocks more than likely so I won't be airing down as low as that, probably around 16-18psi if I had to guess so it shouldn't be as bad

i dont have beadlocks either and safely air down to 13 psi and it still only takes me just over amin like previously stated. i will be going to 10 this summer when i can adjust my deflators. either way the single will still take a long time due to the 38% duty cycle rating of it. if i were you i would save up a little more and invest in the twin compressor. :twocents:

Ok, well the only reason was because the single arb I found on eBay brand new for like 100 with shipping auction and it's the bigger single which is 35% duty cycle, so like 100 vs 500 is a big difference

check out amazon or northridge. i found my twin on amazon for under 500 but i ended up getting it on northridge with the under the hood mount for $500 exactly. both usually have great deals and the later usually has great package deals

Sounds good, thanks for all the help
 
Just on a side note, the tank only makes airing the first tire faster, after that you will be running on the compressor. It is volume not air pressure. I am running 100% duty cycle twin viairs with a 2 gallon tank, had this setup for 3 or 4 years. I bought this kit for under $400 in Canada. It is definitely not as fast as a York or even a sanden but better than the ARB compressors. Jm2c. Hope this helps.
