If any of you have on board air setups with tanks I have a couple of questions.

1) Where have you installed the tanks?
2) Where have you installed the female chucks to plug in a hose at?

If you have pictures I would love to see them. I have an idea of where I want to put mine at, but someone else could have a hell of a better idea.

 

of course i can't find the pics but i know some people have a powertank strapped to the side of their cargo area, come have tanks in the engine bay, some up under the truck etc. i think WATRD has a female connection permanently on his front bumper

 

Here is my setup:

I am always blown away by how much information 4Crawler has in regards to his mods. Thanks for all the work.

 

Psst... "WATTORA" is a club, "WATRD" is me hahahah

As far as duty cycle goes on these OBA systems, can someone go more in depth about it? Is a lower or higher duty cycle better? Whats a good cu ft. flow rate for using air tools etc? I just can't seem to find anything on it.

 

The ideal duty cycle is 100%. That means that the compressor can run continously under load, within reason and subject to some pressure and temperature limitations.

A compressor that has a 33% duty cycle, can only run 1/3 of the time, the other 2/3rds it must rest and cool. It varies from manufacturer to manufacturer, but 20 minutes on, 40 minutes off will give you an idea to start with.

Very few electric compressors are capable of running air tools. You can fill a tank and get a burst, but for most people the only way you are going to get air tool functionality is a belt driven compressor or a C02 tank.

You can see the requirements for some common tools here; http://www2.northerntool.com/aircompressors.htm Note that the requirements exceed the delivery of most portable electric compressors by quite a bit.

 

You need at least 4CFM at ~90psi to run air tools (impact or ratchet) well.

The new compressor/winch combo from Warn does 5CFM at 90 psi. Oasis compressors have high enough flow for airtools also. You can also do the York conversion where you replace your A/C compressor with a belt driven aircompressor.

Some good info on parks off road too:

If you are also thinking about C02 systems, here is how I mounted mine.

As mentioned, if you want to run airtools (90 psi sustained pressure to run an impact wrench) you will need some pressure from a good compressor or C02 tank.
I set my tank at 100 psi, and when I pull the trigger the gauge drops to around 90 psi to power the wrench.

The Powertank can be cranked up to 200 psi and higher with their new regulator they came out with recently.
I had it cranked up to 200 psi at the Fall Colors run and blew everyone way (no pun inteneded ) when it refilled their tires from 20 psi back to street pressure at less than 20 seconds per tire.
I would say more like 10 to 15 seconds.
They are that fast.

Only drawback to a C02 system is you do have to refill it @ about $16 for 10 lb of C02, the size of my tank.
But I do not mind.
C02 tanks are compact, easily removed from the bracket which we did, and carried to each rig for airing backup.

When doing my rig only, the tank stays inside and I stretch the 20' hose around the rig.

 

aww crap

 

I have one of these, http://www.4x4wire.com/tech/portable_oba/p2.gif
but it's just to fix a flat if I should ever encounter one.
I also carry a tire repair kit with me.

 

89dlx, that's a great compressor. is that the one from kragen or pep boys?

I have a 10 gal tank in the rear of my truck with two of those compressors along with their own battery. I also can hook up 2 6 gallon tanks behind each front seat to give me a total of 22 gallons. those 6 gallon tanks can hold up to 170 psi, i just have to find a place that can fill it that high, lol.

I have couplers (thats what the female chucks that you are refering to are actually called) in the passenger footwell and in the back of the truck directly off the air tank.

 

It's from Pepboys. Bought it about a year ago. I couldn't find one where I live. I was in NJ (training for work), stopped in at the local store and snatched one up. Now a couple of guys at work want one.
I figured I stop by the Pepboys in Berlin (I think) CT. They had two. So I bought them both and and will give them to the guys. If they pay me for them of course!

 

I have one of those portable compressors too. That thing is awesome. I am just wanting something diffeent now. As to 4crawler that guy is awesome. I love reading his write ups.
I like the air chuck on the front bumper. I am thinking about having two. 1 on both sides fo the truck. I just haven't figured out where to put them where they are accesible but out of the way. Putting the tank under the bed of the truck where the spare tire was is a good idea. I think I will mount my tank there right in front the the aux gas tank
Thanks for the info guys

 

After looking, I think that if I head down the road of on board air, it's going to be a pulley driven system so I can operate air tools. Only thing I've got on my mind is how the lubrication of the compressor works. Has anyone successfully completed the 'York air conversion' on a toyota?

EDIT: Just found one on toyotaoffroad.com Here's the link for other people's reference.
