    Trying to decide on the right compressor for an OBA setup.

    I realize these compressors are quite different
    - the ARB pushes more CFMs, but is 50% duty rated
    - the Viair is less flow but 100% duty @ 100psi

    What does that really mean in real life? I need some real-world experience to help make up my mind.

    Both models cost more than I originally planned to spend, but looking down the road I'm ok to spend some extra money up front.

    Some intended uses:
    - horns .. reasonable, ie: bus/ambulance, not train
    - filling tires .. stock on the Taco, 33s on the Jeep
    - lockers .. in the future
    - air tools .. maybe, see below
    - crotch-air .. for those hot summer days, global warming fellas, it's coming..

    Will either of these models push air tools (ie: spin off tire lugs) with any success? with/without tank?

    the Viair wont drive air tools without a tank, and even then, it would only run tool sfor a short time. The ARB will, with the use of an air tank of about 2 gallons, would drive an air wrench for a short time. With its 50% duty cycle of 30 mins run time, 30 mins off time, it would be fine for light duty jobs.

    Do yourself a favor and get a Puma. Chearper and will run many tools (depending on air demand) strait from the compressor (though a small tank is advised, and guess what, it comes withat a tank haha).

    100% Duty Cycle
    3.4 CFM (3.0 CFM @ 90 psi)

    HAHAHA sorry, do a google search for "12V Puma compressor", you will find LOTS of info (also check in my build for details on my install with mine...about 2 or 3 years later, and she is still going strong.

    Basically it is exactly the same as the extreme air (costs around $600), at a MUCH lower price

    The air tools were kind of an afterthought, not something I would be doing regularly.

    I will add the Puma to my list of contenders, though.

    So the question comes down to A) do I want 100% duty or B) more CFMs? Since I'm not planning to run this continuously, it's starting to look like ARB or Puma. to be decided.

    oh yeah, your build was one of my "inspiration" threads. The Puma thing didn't click for some reason, but now I see.
    Badass truck you have there, by the way! I put an OME lift on my father's Jeep few years back, big fan of their products.

    A few bolts are different.
    ARB.

    I have had the Viair Superduty kit (2 compressors with 2 gallon tank) It was pitiful. The ARB out preforms it by far. The longest I have had the ARB running was to air up my 4 33's from 14psi, 4 37's from about 10psi and 2 more 35's from about 12psi. The ARB never faltered and wanted more.

    Air tools would be a stretch on it though. But, if you ever plan on getting lockers you're already set!

    The puma is 100% duty cycle as well. So its higher CFM AND 100% ducty cycle. I do run a 3" grinders/cutoff wheel and impact off it, though a large grinder may be a stretch for it and other things that require high flow. With a tank you are good though.
