Anybody use a 12V air compressor. Not the Little 250PSI deals that you plug into your lighter but the other 12volts units. Something reasonably small. I have seen them at Jeep jamborees but not having much luck finding one. Anybody have ideas? What about the 12V air compressors used for the "Bagged" lowered trucks. Will they fill up a tire without burning up?


You serious off roaders must know.


Thanks in advance

Northern Tool has a few to chose from.

I think you can mount a compressor to be driven off of the serp. belt in the second alternator location. I forget who told me that, but that setup would be very cool... Too bad for those of you with dual alts.


Might be worth checking into.

I don't know how "small" of an air compressor you want, but I used to work for a company that used 12V compressors for air bag suspension systems on buses. We used a Thomas (http://www.thomasind.com/) air compressor.


Here's some on ebay:

I wish I had all the money I've spent on 12v compressors. Haven't found one worth a d*** yet! Getting one of our rears to 80 psi with a 12v could take the major part of a day.


Man, if anyone knows of one to mount on the engine I sure would like to hear about it.

Try this one on for size.

4Doors that is sure a nice setup that vmac has. Do you have any idea on the price? I'm guessing 2-4k http://www.dieselplace.com/forum/smileys/Geek.gif

Duramax Dually, I am one of those "Jeepers" you may have seen at the Jamborees. Yes, there are many options for serious 12 volt underhood (or other loacations) compressors. In my Jeep, I currently have a serpentine belt driven compressor. Output on the order of Rated at 4 CFM at 90 psi while running at 1200 rpm, and capable of 8cfm. Such a setup can be seen here:

A nice York setup on a Jeep will caost you $500-$800.


As far as electric compressors, lots to choose from. Check some out here:

These are not the wimpy cigarette lighter types we have all wasted money on over the years.Edited by: jeephauler

I have no idea on the cost. I saw them at a trade show in Vegas a couple years ago. At the time, way to expensive for me. Great idea, just to much for the amount of use I personally would get out of it.

hope to have a serpentine pump to play with soon buddy bought it and doesnt have the time to work on it. i got the time and no money. hes going 12v.

try this one for a real air compressor

more cfm than any other 12v compressor that I'm aware of


if that's not enough, you could run it at 24v for almost twice the cfm


more info here: http://www.oasisoffroad.com/


I don't use a 12v compressor, but I looked into it in order to supplement my existing setup. I currently use liquid CO2 from http://powertank.com/start.htm

I called vmac the turn key set up runs for 7khttp://dieselplace.com/forum/smileys/Ouch.gif on the 73cfm unit.

EASY, go to Ebay and put in 450c, comes in 24 vdc and 12vdc. Puts out max psi of 175 and a 100% duty cycle. 23 amps max, weighs about 9 lbs. This is wht they us in all the air ride suspension low rider trucks. Banks also uses this model for their engine brake. Made by Viair, found locally at 4wd shops for around 300.00 but found on ebay for 200.00 plush ship. Company in Canada and Co in So Cal I think. Goto Viair site or tellico4x4.com and they have lost of info. Storage tanks from justairtanks.com are several good sites.

Hahahahaha

I looked at all those $$$$$$$ setups and got better then all of them for 79.00.

I put a 1000w inverter in my truck for 79.00 and run a regular compressor I already had. I got the compressor at home depot for 89.00. Its a small twin tank and it will fill an H2 tire in 4 mins.

problemchild,

Do me a favor.

Taks a look at the 1000w inverter and tell me what amperage it's rated at. Then check your compressor for the same. I'm not sure your inverter can handle a 110V compressor especially the startup.

Well you get what you pay for!

Hoot

The compressor doesnt have an amp/hp placard. If I had to guess I'd say its 1/2-3/4 hp. It fills the twin tanks to 110psi in about 2 minutes. I then can air up my tires. It usually takes two full runs or 2 tanks.

My inverter is actually 800w not 1000. I made a mistake.
I have used it to air up the tires numerous times. It works great.

You want a laugh. My coffee maker actually puts a bigger load on the inverter then the compressor. The coffee maker (110v) pulls 60+ amps when converting 110 to 12v.

I calc the 800W inverter would draw a nominal 70A and provide apprx 7A of 120VAC. Max of 140A w/15A of 120VAC for a short period. Course one could skip the arithmatic and chk the value stamped on the fuse http://www.dieselplace.com/forum/smileys/Ermm.gifEdited by: ShumDit

MY OPINION/SUMMARY:


<$50 Cheap disposable 12v compressor. Available at most Targets and autoparts stores. Fractional CFM rating.


$150-450 Many manufacturers produce these for 4x4 and air bag use. Higher dollar within this range gets you more CFM and duty cycle rating. Use with larger onboard tanks will allow intermittent air tool usage at a duty cycle depending on your setup. From fractional CFM to 4 CFM. (quickair, viair, arb, extremeaire)


$500-1000 York based compressors either 12v, 24v, or engine belt driven. Great for off roaders and air tool usage. You can set a bead on a tire w/ these. Tanks are recommended, but optional. Duty cycle is constant for some, but a non-issue in most cases due to high CFM ratings in the 4-25 range. http://www.onboardair.com I've been looking at the XD2000 made by oasis off road, but I probably won't purchase for another year.


In the more $$$ than I can afford or justify category is professional compressors. By professional, I mean you should be making money using one of these. They are expensive, but may be a better alternative than towing a compressor to run a jackhammer.


$300-600 Liquid CO2 - I have one of these setups from http://www.powertank.com I've used it successfully for a few years now. Pros: Very portable, can run w/o electricity & engine, high CFM Cons: needs to be filled up peiodically, not good if left out of cab in freezing temps


Home brew inverter/120v systems: Better than the disposable 12v compressors.

Viair is the industry standard in small durable 12V compressors. I mounted on eon my 2500HD for air bags and tire fills (I surf fish and need to get form 15 back to 50 or so multiple times a day) and it works great! try (www.truckspring.com (http://www.truckspring.com) or www.airliftcompany.com (http://www.airliftcompany.com) ). Many other sources as well.

I to use a Viair compressor. I use it to air tires and to run my fire truck horn I mounted under the radiator. It is a great compressor. I have a 3 gallon tank with a pressure switch that shuts the compressor off at 125 psi. I also put a pressure regulator that I set at 60 psi. I get 15 sec of horn without the compressor kicking on. I put a switch so I can switch between my factory horn and air horn.

I have a belt driven York on one of my Land Cruisers. 10 years with no problems, great for air tools. At the same time, while I was in Iceland, I got a couple of CO2 tanks. The CO2 is NICE!!!! I can air up a 38x15 from 2 psi to 30 psi in under 5 seconds. With temps in the teens and 20s a 15 lb bottle is good for 12 such air ups. At higher ambient temps it will do even more.

Here's another source - http://www.extremeoutback.com/
They have all the accessories including a pressure switch for automating electric setups.

Good people with some unique "stuff".

Try AW direct part PAC3 for 379.99 its a 12volt 3 gallon tank 3/4 hp 0- 120 psi in 90 seconds 100% duty-cycle. There web site is www.awdirect.com (http://www.awdirect.com) My new truck a 2003 Chevy C4500 has air on borad to run the engine brake and horns.

I have a viair 550C that works great. Have not had any problems with it and it is rated for continuous duty.
