    Air Tank Size Recommendation

    I am about to install an ARB air compressor and was thinking of adding a tank for air tools (take wheels off and ratchet to fix odd thing on comp truck)

    What size tank would be the min for air tools - anyone know or have a formula to work out?

    Would and old rangie air suspension tank do?
    I also have one about half that size - easier to hid some where would that do?

    Also any suggestions on where one can get some heat shielding wrap for hoses and fittings in the engine bay?
    Thanks in advance

    I think the problem will be the compressor not up to running air tools etc rather the capacity of the tank being an issue.
    Sure it'll fill the tank to a set pressure and you can run a rattle gun or whatever for a few seconds then you'll have to wait for the compressor to fill the tank again.

    Just my 2 cents.
    Cheers

    yep, agreed. The little compressor I had setup on a small tank


    that one

    takes about 8 minutes to blow that tank up to 100psi which is enough air to get one tyre up from nearly flat and just enough air to crack all the nuts on one wheel of a deefer providing that the nuts arent over tensioned and have greased threads and face.

    IF you spin the nuts all the way off its got enough air for one nut.

    the tank is off of a compressor I bought from kmart auto in townsville from memory for less than $100 and the 12v compressor that now fills it was $79 from super cheap at about the same time. The tank, according to the sticker is

    6.0l
    140psi
    -10 - +100 deg C

    its getting worse for wear now being some 5 years old and being the compressor that I lend out when people need a loaner for 4x4ing.

    I've got a 9L fire extinguisher tank and as suggested, it's too big for the compressor. It's good for charging up the tank and reinflating a tyre quickly, but I reckon it then struggles when it has prolonged work to do - like inflating 4 tyres, as it must keep pressure up to both the tank and the tyre.

    I need to :

    1. get a smaller tank.
    2. rig up a tank by-pass system
    3. fit an endless air compressor

    I like option 3, so I'm doing nothing while I save money.
