Topic: OBA setup

[Celt]

So I have questions.... 

1. I like the idea of installing the tank where the spare tire goes and the compressor in the storage compartment. Especially for water/mud crossings..
Any issues with this setup?

2.  I think KnightRider is running this system Air Zenith OB2.  Can you run Air Tools off this setup?  My Google understanding is Airtools require 3-6 CFM at 90psi to run correctly.  Is this true? The AZOB2 runs 2.66 CFM at 90psi

This is our max price point for OBA at this time (aka no ARB system).  If the AZOB2 can't realistically run air tools - we are looking maybe at this option...... VIAIR 200 PSI Ultra Duty Onboard Air System which only runs 1.13 CFM at 90psi

3. I do like the Stainless Steel Braided Air Hose vs. the VIAIR 30' coil hose.  And I notice the AZOB2 has 1/2" NPT Air Tank Fitting vs. the VIAIR 3/8" NPT Intake Port.
But are these differences significant?

4. Anything else I need to consider?

As always, I appreciate all input and help with spending more money......

Prior to purchase the Winter Mojave run will give you lots of opportunity to eyeball everyone's vehicles to see how they are setup. Both of mine that are going have OBA but in different configurations. One is up front the other is in the spare tire area. I'm not partial to either one, they are both really great setups. On that run you can see the various compressors and tanks in action with fill times for airing up or if a bead gets popped etc. Both of my compressors are Viair rated for constant run for 35 inch tires. I've aired up 8 35's consecutively after a trip without any issues or overheating but that compressor was working very hard and I wasn't thrilled about working it so much. As a rule air tools can be run just not optimal with them so a short run like a cutoff tool etc. wouldn't hurt anything but long term use would as they aren't designed for that type of use. So check out the various setups and ask a lotta questions around the campfire during Fire Jenga sessions.

1. I like the compressor in the storage area as it is not used otherwise, too hard to access when packed for camping. 

Heat has not been an issue and the ob2 has a fan on the head.

2. I pieced my own kit together as the air zenith kit was not available at the time.  It is a nice kit though and includes everything needed.

Air tools are possible, any on board air system is capable of running tools if you have a tank, the output of the compressor just refills the tank quicker. 

With the 200psi of the ob2, you will need a regulator to reduce the output pressure for air tools as most air tools are designed for 90 psi.  I have no issues running air tools, they came in handy while installing Henny's suspension at my house as I do not have an air compressor in my garage.

3. No difference unless you are running air bag suspension on a lowrider. 

4. Having a quick disconnect plumbed to the front and back of the truck help make the OBA easier to use.  I have a regulator and air dryer/lubricator  on quick disconnects so that when using air tools I can regulate the pressure down to 90psi and it removes moisture and adds oil to lubricate my air tools.

I'm ordering and Air max system with dual Viair 444c compressors and 5 gallon tank.  It was recommended from several people at the off road show.  It's under $400 on ebay.

4.  I think that you can get more for your $ by piecing together your own system.  I got about $200 into my dual comp. set-up.

We'll talk

Great idea, Celt.  But we are hoping to have it installed prior to the Winter MRT ..... not sure if we can get a system together that fast tho

KR - awesome info!  Thank you!

If you are looking to build a system, I have the Puma pump I bought from Joe I can sell for the same price I got it $100.

Here's the link.
