ONBOARD AIR COMPRESSOR
I WOULD LIKE TO INSTALL AN ONBOARD AIR COMPRESSOR SYSTEM, THAT WOULD I COULD USE TO AIR UP TIRES ON MY TRUCK AND FIFTH WHEEL. LAST SUMMER I HAD A COUPLE OF TIRES THAT WERE LOW AND I WAS QUIT A WAYS FROM A SERVICE STATION. I ENDED UP BURNING UP 2 OF THE THE SUPPOSED HD COMPRESSORS THAT PLUG INTO THE CIGARETTE LIGHTER. I WOULD LIKE TO ALSO HAVE AN ONBOARD AIR TANK WITH A LITTLE VOLUMM TO IT. PLEASE POST SOME PICTURES AND LIST OF PARTS. THANKS

viair 480 compressor with at least a 3 gallon tank. a little costly at around $400 complete, but worth every penny.
i have twin 480 compressors with a 12 gallon air capacity, and can run my 1/2 inch impact wrench all day long.

York Compressor for On-Board Air

Not sure if the unit for sale is the correct york style to use, just saw the ad and threw it up here for example of prices. Off Roaders use this setup quite often.

I have a 1994 H1 Hummer that I have owned since 1996. It has the CTIS (central tire inflation system) on it. The CTIS has always leaked so I have to turn on the onboard air compressor at least once a week to maintain proper tire pressure. I have not had any problem with this compressor. I just went out and got some info for you. I am not exactly sure if I got the model number right because it is in the back side of the compressor and was hard to see.
Rough measurements: 11"x8"x5" and does not use a air tank.
Manufacture Pacific Scientific
12 volt, 22 amp
Model # TA-305t-DCx
No idea of price but has been very reliable.

Here's my OBA setup got an Air Zenith OB2 on the left and a viair 350c on the right and 5 gallons of air also have an electric solenoid on the right for my train horn and one on the bottom for a drain. Couldn't get it in the pic, but also have a 50' air hose reel on the left side of the tank with an impact wrench and air chuck for changing/airing up tires.

NEED A WIRING DIAGRAM
Got a Viair 380c compressor with a inline pressure switch and a tank. i need a good wiring diagram for hooking this up on my truck. I know that it has to go through a relay of some type. Thanks

I have nothing specific to add except that a combination of a power inverter and a common 120VAC compressor is a much more capable, versatile, and cost effective setup then a pricey 12VDC compressor. That's what I use, nothing fancy or pricey, just works. I do have a couple 12v air compressiors but they just don't cut it.

It's not like I planned out the setup, I just used what I got. I'm cheap.
My biggest advice in doing something like this is to error towards the largest inverter that fits your needs. Just a little too small is way to small, and you can't combine a couple to run big things like you can dc stuff and air compressors, etc.

10 gauge wire from the battery to the relay, then circuit breaker then to compressor..
14 gauge wire from a switched power source in the fuse box, to the 5 amp fuse holder, to the switch, then out through the firewall to turn the relay on and off.
this way the compressor is off when the key is turned off.
the toggle switch is optional. i like to use it so i can turn the compressor off if not needed.

5000W inverter and what claims to be a 3HP 150PSI compressor, not sure the cfm. I also have a little 1200W generator and a 40A converter so I don't always have to run the truck. Its no where near ideal or quality stuff but works, does a lot and I got about $400 total invested.

For less than $400 I've got a 12v 100% duty cycle compressor with 2 gallon tank in my truck. It's only about 1cfm though and I'm looking at adding some additional capacity and cfm.

I'm guessing you mean 3 gallon compressor? 3 hp is a pretty good size motor and a 1200 watt generator won't provide enough amps to run one I don't believe.

No the 1200 watt generator will not run the compressor, I don't ask it to. It's job is to provide other power and charge the batteries in the truck via the converter. That will provide up to 40A and 14.5V to the truck. With some power to spare for power tools. The compressor will only start off the big inverter in the truck.
I also have 3 of these 12 Volt, 100 PSI High Volume Air Compressor For $20 each they have been great and I haven't killed one yet.
