DBoat I read through this thread and didnt realize that a tank could hold that much air.. so we need a build thread on the home grown inexpensive version, we need a parts list, etc.. also, where do you refill them? do you just through yours in when you go or do you mount it up somewhere in the Jeep?

Moabrubi If you have the $$ get the York. They are uber fast and no need to refill CO2 which sucks. When I can I'm getting York so i can get rid of my little Viair that takes 10,000 years to fill a tire. i will say it is a reliable little unit though, It has filled 6 Jeeps tires at once no problems (just really slow) because I was the only one with air.

Sahara707 I have both the Viair Compressor and the Smittybilt Tank. Last year I was coming back into Virginia City and it started to snow, lightly. It must have taken 15 to 20 minutes to fill the tires with the Viair air. I think I'll carry the Viair on the trail, but when I get back to the truck and have to fill up four tires I'll wipe out the tank.

Jerry Bransford One thing to keep in mind about a C02, which I have run for almost two years now, is you don't need an expensive regulator for it to flow high volumes and not have problems freezing up. I bought a regulator online for somewhere close to $40 and it fills my tires as quickly as my previous MAD-FAST York OBA system did that I had on my previous TJ that was stolen last year. <5 minutes to refill four 35" tires from 7-8 to 35 psi with both the York and my present C02 system. Neither has it ever frozen up. In total, I have under $150 into my home-made C02 system with an aluminum 10lb. tank, regulator, and hose. I spent $80 on the web for the aluminum tank brand-new.

BentMetal I have a viair, I have a Warn Powerplant winch, I still choose my Powertank every time to fill my tires at the end of a run or if I have to use my air tools out on the trail. Powertank regulators are pretty special and are made to flow large amounts of CO2 along with the hose that is specific for the cold temps that CO2 produces... a frozen regulator or a cracked hose is pretty useless when you need to air up.

Powertank is portable, powerful and made in the USA by a fellow wheeler.

Kilby, Sanden, and Yorks are pretty amazing but do cost a pretty large sum of cash and are not portable. The Powertank can be moved from vehicle to vehicle; I use the same Powertank that I use wheeling when I take my dirtbikes out for the weekend, or when I travel in the family car, it is great for roadside emergencies.

X2 with Jerry B on the smitty crap, made in China, sub-par junk that is imitating. Never, I mean never spend your money on rip-off knock off stuff that is stealing from true off-roaders, the few dollars you save you will spend in the end and you could have supported a business that supports us.

I will now get off my soap box

blue6tj I have the Viair and love it... I mounted mine behind my spare and above the gas cans.

Ageless Stranger I'm gonna go ahead and hang on to my lawnmower engine.

rrich I think you'll find the misconception that the Sanden does not have a separate oil sump like the York is just that - a misconception.

Since it's round it doesn't look like a conventional lawn mower engine. The end near the clutch is a separate chamber housing the main bearing, crankshaft and wobble plate. The pistons are lubed by splash, just like your engine.
That end is it's own oil sump - like others, you use a dipstick to check the oil level. There's a big plug on the side to put the dipstick in.

The other end has the reed valves - it too needs a little bit of oil, as does the external check valve. The 2 ends are connected only with a tiny vent hole to equalize pressure for the original AC application with pressures of up to 300 lbs. Oil is not shared between the 2 ends.

When I do an engine oil change, I let the air inlet suck in a few drops of Ester oil, then let it run until that oil is expelled.
Some folks hook up an elaborate system to catch oil - then they put way too much oil in with an oiler or just pour lots of it in.

Some even hook up an elaborate system to recycle the oil. Recycling puts the water back in the compressor - not good!

Take one apart, you'll see.

I've installed maybe a dozen or so, the only problem so far was one where the clutch self destructed - not an oiling problem.

A good source - sometimes a compressor gets replaced because it leaks a little - won't hold freon for a long period of time.
Shops replace the compressors rather than repairing them. (Repairing them seems to be a black art!)
But for an on-board air system it doesn't have to hold air for months at a time.

Most shops that do AC work have several cores laying around. Many will give you several for free! When thy buy rebuilts, they need the $5 core, but not for new ones.

As far as oil getting in your tires - the small amount of Ester Oil vapor for AC's does not hurt the rubber - if it did it would destroy all the seals and O rings in your AC system in short order.

The web has lots of diagrams and pictures of the Sanden and parts are relatively cheap.

Sometimes the core just won't pump at all - take off the end plate and clean the reed valves. A tiny piece of grit holds it open. Same like your shop compressor.

Ah that makes sense then. I won't go Smittybuilt, the shops here won't even fill them anymore since they have been being built in China. So it would be a big expensive paperweight.

All of this.↑↑↑

was that there power tank set up?

Yeah, I did some research & calling around & I'm able to get a new 10lbs tank, filled & regulator for $150 locally. Thats a way better deal than power tank.

The only reason I've gone to C02 now is because the TJ the York was installed in was stolen and I can't afford to install another York into my replacement TJ.

rrich I considered the Y0RK - it's like mounting a lawn mower engine under your hood - too big!

I went with a Sanden - same as your AC compressor - small, round, fit's nice. It leaves room for a 2nd battery and other goodies - winch controls, inverter, battery shut-off switch etc..

York's put out slightly more CFM, - around 10 CFM.
The Sanden is about 9 CFM. 10% less.

The difference filling a 35 is about 15 seconds longer.

Junkyard Sanden's - $10 -- York $50-100
Mounting bracket is easy to make too.

With an air tank it will run an air tool, but I've never felt the need for one on the trail.

I've used a few different that friends have set up on their rigs, from ARB, to VIAR to the Warren to a little SLIME one I bought from AutoZone for $59.99 and a few others. The SLIME one did just as well as the ARB with a 2.5 gallon tank. I also got tired of driving into a town on 10-12psi to spend a butt load of quarts and an hour to fill up.

That is what convinced me to go with a CO2 tank.

AirWerkz Systems look great. I like the VIAIR units.... very dependable and always have air when you need it.

I have used this consistently since installing it in 2008 for all of my runs, filling tires, other Jeeps' tires, etc. This setup is Baja proven, having filled my tires when I was 50+ miles from the nearest full-service gasoline station (in Baja, Mexico)

Filling up between Puertecitos and San Felipe - ~20 mi. from the nearest Pemex station.



Me standing next to my Jeep - fully loaded for Baja!
My camping gear, plus my Viair X'treme Duty equipment all fits together without losing too much space.


No gas stations for miles, but my Viair filled my 33" tires (~5 min. each 11 p.s.i. to 32 p.s.i.) and took me from Laguna del Diablo to Ensenada without having to stop at a Pemex Station.

Looking north

Looking south
Nice! I'm jealous!
