I decided to look for a permanent air source for my truck. I thought about a co2 tank, but didn't want the hassle of refilling and finding a place to keep it.

Next up would be an air compressor
I have been running a Puma 12 volt that I keep inside over the rear fenderwell for some time. I was trying to find another place to mount it, but it isn't water proof .
The other option would be to install one under the hood. I wanted to save all the space I could, under the hood, in case I decide to run another battery.

Next thought would be to to mount a compressor exterior. Since there is ample real estate available under the back of the truck, this was a good option. So it would have to be waterproof.

That's where the ExtremeAire compressor comes in. These are really good compressors that have great stats, plus they are waterproof to so many meters, for so long. Perfect
They make a few different models, even 24 volt if needed. The standard compressor is 3.4 hp

Here are the details on this one

ExtremeAire 12 volt Compressor
$414.95

The ExtremeAire Severe Duty Compressor is setting standards for high output compressors. By utilizing a 3/4 horsepower fan cooled motor, overheating is a thing of the past. Designed to fill the largest 4WD tires or the highest-pressure RV tires, this unit can fill tires continuously with no fear of motor burnout. With a 150psi working pressure, you can fill air tanks and run impact wrenches to dismount and mount wheels easily. For clean air in the dirtiest environments, the ExtremeAire uses an oversize UNI-Filter that is crush proof, washable and reusable. All major motorcycle teams use UNI-Filters for Baja and motocross racing. In addition, the fan shaft has a sweeper filter to keep dirt and debris out of the motor and brushes, at the same time, allowing moisture and condensation to escape. The ExtremeAire is permanently lubed with sealed bearings so it can be mounted in any position making installation much easier. Every ExtremeAire utilizes stainless steel fasteners Loctited for a long and trouble free life in the highest vibration applications. Uses for the ExtremeAire include 4WD, RV, Agricultural, Construction, Motorsports, etc. No other 12-volt compressor has the speed, continuous duty cycle, output, pressure rating, and reliability that the ExtremeAire can deliver.

Tech Specs:

- Continuous duty cycle
- 3/4 horsepower motor
- 30-amp draw at 35psi
- 40-amp draw at 150psi
- 4 cfm free flow rate
- 150psi max working pressure
- Can be mounted upside down
- 14" long, 6" wide, 9", tall.


Next choice is the ExtremeAire Magnum
ExtremeAire Magnum
Imagine an ExtremeAire Compressor with TWICE the power and speed, all in a package only 2" longer than the original! Now you can have a continuous 12 volt compressor that will put out 6 CFM free flow and a whopping 2.6 CFM at 100 psi. Nothing in its size, class or price range even comes close! The ExtremeAire Magnum utilizes a 1.5 HP fan cooled motor and longer piston stroke to make the impossible possible. The Magnum has all the key features of the original ExtremeAire such as superior filtering, stainless steel hardware, heat dissipation cylinder coating and powder coated filter housing and fan shroud. Plus it can be mounted in any angle or position, even upside down! Sealed bearings mean no servicing or lubrication is necessary. Uses include filling tires, running air tools, air bags, lockers, train horns, etc. It is the perfect unit for jobsite chores or ranch duties. Since the unit is totally sealed from the elements, you can mount it under your truck on the frame rail so valuable storage space is preserved.

Specs:
-1.5 HP Motor
-95 amps @ 12.5 Volts DC
-Continuous Duty @ 150 psi
-6 CFM @ 0 psi
-2.6 CFM @ 100 psi
-Weight: 20 lbs.
-Dimensions: 16" long x 6" wide x 9.5" tall


My final decision was to go for the Magnum. I wanted to put the worst case scenario in as far as size goes, Since it was only 2" longer, it still will fit where I want to go.

Here's what brown brought me


Next post I will go through the mounting/install
 
Along with these items pictures were 25Ft high pressure reinforced brake/air line. 25 ft black and red 4 awg 2 quick disconnects front and back . a bunch of quick snap air fittings. a head pressure bleed off switch, so the cylinder unloads for start up. air regulator solenoid. 80 waterproof circuit breaker , 100 waterproof relay and various terminals heat shrink.

I made a plan on where I wanted it, so I needed to build a crossmember to make it work
Here's what I came up with








It fits perfectly between the frame rails attaching to 3 threaded holes on the frame each side. It doesn't hang below, the rails at all. I will make a skid plate to protect it and put heat shields under the exhaust pipe. I intentionally mounted the heavier compressor on the passenger side, to not make the FJ lean any worse.
Its now painted and will be install tomorrow. I will take more pictures of the electrical, air routing when it's done .
 
Pretty slick set up Don. Nice writeup
 
Thanks
Yesterday was the very, first day, Since I have been back from SEMA, that I even walked in the garage to do some work. I have been sick, since Thanksgiving. It felt good to grind some metal and do some stuff under the truck. I hope to have it operational by Sunday. I will post more pics of the rest of the process
thanks
 
good idea, second dibs, please :bounce:
 
Yes I do want to sell my Puma
Only thing missing is the handle. I was going to make one, but I just haven't had the time .


Part 2 is complete. After test fitting the bracket some adjustments had to be made. I actually wheeled with the bracket in place yesterday. The adjustment I made was making sure there was a separation between the compressor frame and the body above it. I thought I allowed enough in the original fabrication, but after pulling the bracket, today I saw rub marks on the body above the frame so now it is spaced more.

The compressor and tank were mounted , pressure switch plumbed in, blow of valve attached and everything from the compressor to the tank is now complete.

The hard stuff is done.
Next phase is plumbing the air fittings and running all the electrical. I hope to have it running this week and do some testing.

The entire unit together weighs 47# . I'm not sure what a CO2 set up weighs full, but if someone could give me the weight, that will be a good comparison.

Here are some pics mounted






 
First class as always Don

Looking forward to the air up numbers.
 
If I have it ready by the meeting this month it would be good to do a side by side
Air down to 10 psi ExtremeAire versus Puma
4 tires 35" so it will show what a real world air up would be. Afterall compressors loose a little efficiency after a few tires.

I want to have it working this week anyway.
 
I just wanted to update this thread with some real world info
At the CSC meeting , we had a compressor shoot out between the Puma and the Extremaire , Then the Extremeaire and the a/c compressor off the motor
The Puma Filled a 35 General Grabber on a 17 inch rim from 0 psi to 24 psi in 3 minutes
the Extremeaire did the same test and got 34.5 PSI
The a/c compressor, blew both of them away getting 40psi in less than 3 minutes . Obviously that would be the very best system to run if it could be done in a kit for different platforms, but I am happy with the ExtremeAire because of its performance and ability to mount under the truck , since it's waterproof to a few meters.
The cost of the ExtremeAire is more than double to the Puma, so that is a consideration for sure. '

Real world air down and air up happened yesterday, when a few of us did Asbestos Point. I put my Hankook 285/17/17s back on for trails. I aired them down to 15psi . After the trail I was able to air them back up to 40psi It took 1.35 minutes, air each tire up. I was totally happy with that. I also decided to try an impact wrench, for changing out all 4 tires . I didn't run my motor and did them all with no real effort. It cycled on during the first lug, but only slowed down a bit on the last of 6 lugs. Since I run the Odyssey 2150 battery It didn't even break a sweat . For the trail I will keep the truck running, but at least I know it can handle it , with no problem .
 
Don, you realize youre spoiled rotten now dont you?!

:flipoff2::hillbilly:
 
How has it held up over the years under the truck etc? I aks because Im doing same right now.

Might be a while before you get a response. OP hasn't posted on mud since December 2014. Last logged on September 2016.

I would relocate the compressor air filter inside the cab.
Oh I mounted the entire thing in truck beside rear drawers just fired it up now. winch fittings leaking away I have to regulate the PSI down for the winches air brake I believe. starting to look at this entire thing and man theres so many more things that could wrong with the new set up more moving parts. SO Im making it bullet proof. or trying
