On Board air re re revisited

[ToolManTimTaylor]

Dude I Gotta give Diesel Injection Service a shout on this baby!



Only How Many Amps does she draw?



746 watts in 1hp x 2. 5 = 1865



1865 watts Divided by 12volts = 155. 41 amps what did i do wrong?





One of the most powerful air compressors on the market!

* Inflates a standard size tire in less than a minute

* Powerful enough to run power tools without a tank

* Can run either on 12Vdc or 24Vdc battery

* 2. 5HP at 12V and 5. 0HP at 24V

* Average outputs of 14 cfm at 12V and 16cfm at 24V

* Max. pressure at 12V is 125psi, max. pressure at 24V is 175psi

* Utilizes heavy duty York compressor

* Winch-type motor runs at 1650 rpm at 50psi



Price: $729. 00

(includes air compressor and pressure switch)

After looking at PTO driven units

Good info on these from the manufacturer Oasis Off Road

i looked into them a little over a year ago but they are really big and the draw is huge so mounting would logically have to be near the batterys and solid. i just never took it any farther. But boy does that thing put out some air:--)

Good eye ted (oasis sticker)

Has anybody tryed the V-Mac system?

The flyer I got says up to 73. 5 cfm and 100% duty cycle 175 max psi totaly kit wieght is like 150lbs sound to good to be true but it is pricy. I was curious if any one has/does use this system?



Thanks

Craig

That compressor is only 25% duty cycle, and far to pricey, check this one out... http://www.extremeoutback.com/Compressors.htm Call and talk to them, they will answer all your questions, very nice people.





Later, Rob

That oasis unit uses a York model 210 compressor driven with a winch type motor. Onboardair.com sells everything you need to mount a york 210 to your 24v engines, thus eliminating the electric motor from the equation. The Yorks are just about indestructable, and are easily found in junkyards in Volvos as well as many other cars. I have a few that I have pulled out and I sell on ebay for those people that don't like going to the junkyard. I am waiting for onboardair to come out with a kit for my 12v, or I may end up fabricating the kit myself, who knows. In my opinion, running the compressor from a belt off the engine is a much better idea than buying an expensive, inefficient electric motor to run it.

Rob... cool site, I have two new tanks waiting for me to decide which pump to get... I plan on mounting the tanks permanently in my CJ7 and my Dually and moving the compressor back and forth between with quick disconnects. . this looks like a very good candidate

I'm in the process of trying to finish the install on my truck.

My application is for running Haskel Booster Pump.

Thinking of replacing right front coil spring because of the added weight?

How Heavy is the Compressor?)#ad






Straight six jeff's setup didn't look too heavy and I thought his engine compartment was stuffed (Alltho extreemly cleen install)





I also Forgot to ask If anyone is running a PTO driven compressor. (Saw one on a 6. 5 10 yard dumpster truck yesterday and of course it was hacked in but man that thang flowed)

 

[rbattelle]

I notice Kilby is selling the Oasis compressors now (link) .



I was planning to get his engine driven compressor, but decided to rethink the idea.



The Oasis XD2000 looks like an impressive unit, and with a dedicated battery could be run with the engine off (for a short time). 7. 5 CFM @ 100 psi.



Anyone with any experience?

[Mhannink]

has anybody considered useing another ac pump or their one already existing figure out a bracket and put that on use a switch to enage it like ur factory air and you can have more cfm then you want at up to 500 psi i know some jeeps have it like that if u dont belive me on the psi just think how much it takes to blow the ends on a 1/4 thick steel air bumper on a jeep oh yeah and only took a few minutes i have thought of this for sometime so anybody interested pm me for a few more details and maybe you can try it if you want

 

[ToolManTimTaylor]

Whoah What the?? How do ya like that This thread came back to like after allmost three years (2. 75) Well as alternatives I have looked at a ton of stuff.



Did absolutly nothing about it but looked anyway. From looking at belt driven , high tourque electric , high volume Viair suspension pumps to a big ol' verter and a small DeWalt unit tucked away in the tool box.

 

[Straight6Jeff]

For a short time, I was running my Kilby engine driven set up at 285# (air hammering rebar into the ground). The syustem took it in stride. I high Idled the engine to 1500 RPM and added a buffer tank during this time so that I had 30 gal reserve (instead of the 6 gal normal). Notes on running this pressure... Blow off valves were inoperative, hard tanks were astm rated to 150#... Basically all safety features were disabled. I wrapped the truck mounted tank in scatter-blankets just in case. Everything held just fine... except the air hammer... it was only rated to 90 psig. Sorry Craftsman. . not sure what went wrong!!!!! No, I did not try to get it replaced under warranty, as that would have been just wrong!

 

[Ted Constantine]

The question is what do you want to have the air supply for?



For continuous use like jeff was talking about engine driven is great. If you are using it for emergency (every once in a while) airing up tires, running air tools, I don't think you can go wrong with CO2. It is just so fool proof and has no moving parts.

 

[jdooner]

TTMT

That would be 746w divided by 12v=62. 1666666

 

[ToolManTimTaylor]

AHA LOL Thanks! I knew the math was wong. Like I said now that this has come to past a couple years ago I really ended up doing nothing anyhow. Buuuuut now that this thread is active again I am re entertaining the thought process and I am thinking of Viair (At least for the air horns anyways) . I did need flow numbers that were pretty much too large to be $$ worthy. It was for running air tools AND if hooked up with a bed mountable tank (removeable as well) I could handle irrigation seasonal shutdown. But that is better left to the tow behind unit. So it was not so much poundage but Cubic Footage.

 

[Straight6Jeff]

The CO2 setup would be good also because you could charge for hits off the co2 tanks at parties.....

I think that's nitrous... No buzzz from CO2, but it helps the beer get outa the keg.



I read on another site about a Viair type comp for occasional use. Same type, looks similar, etc. but it was only $28 from the local parts shop (Checker). They compared actual time to inflate offroad tires back to highway pressures, and the MV50 beat the Viair.



I installed one (with a tank) to run the airhorns and I swear they're just as loud. I figured if it wore out, I could replace it with something better.

the 550 series ViAir is rated @ 2. 90 cfm @ 100% duty cycle. Which equates to a 0-145 psi fill rate in a 5. 0 Gallon tank in 4 minutes. BUT it can do so non stop. But then again this is not a 28 dollar compressor either.
