G'day all,
I need to run an air riveter for one job only and am looking to set up an air reservior tank fed by a Big Red.I can handle the air plumbing but need to know the correct way to set up cut off switches and the like.I don't have room to cart a 240V compressor and was looking to set up an air tank anyway.Will be sourcing a tank from a truck wrecker soon.
Air riveter sucks 4cfm@90 psi flat out.I did a search but was hoping to pick up a little more detail with regard to switches,wiring,etc?
Any info greatly appreciated, Ian.

Ian,

You can get a air pressure switch from ARB which they use on the diff locks or there is on that I have used that is adjustable.

To wire them up all you have to do is attach the positive wire to one of the wires that are on the pressure switch and the other wire from the switch to the positive wire on the compressor. That way when the air tank reaches the set pressure the air compressor is turned off and when it reaches it set low pressure it will start again.

I believe that the pressure from ARB is set at about 100psi and 80psi, that you might have to check with them.

In the past I have used old fire extinguisher as a air tank. They are a pressure vessel made of aluminium and not too big and wont rust. A 9kg one would be a good size if you can hold of one.

That's correct Wayne, about the ARB cut-in and cut-out pressures. I use one in my set-up with the Max Air which is always full or close to it.

As for the plumbing side of things, you'll need either a manifold or at least a "T" piece. I use the "T" piece, so that the the compressor is altered as follows...... The outlet nipple is removed from the compressor and the "T" piece is screwed in it's place. The ARB cut-out switch is placed into one arm of the "T" piece and the air hose or nipple etc is attached to the 3rd part of the "T" piece.

I know you can buy these snazzy manifolds that have about 6 ports; 2 x 1/4" BSP and 4 x 1/8" BSP from memory. This is the way to go if you have diff-locks or if you want to run permanent hoses to front and/or back of vehicle for tyre inflation, or if you have air horns like mine that require a permanent supply of air to the solenoid that operates them etc.

Hope this helps....

Roachie,

I use to make my own manifolds out of 1" square aluminum.
The number of ports that you required would determined the length of the block and then it was a simple matter of drilling and tapping .

Last week I got a price on an adjustable pressure switch and relief valve ( $50 +$25 ) Then on the weekend bought a cheap 240 volt GMC compressor from Bunnings for $75. I cut the cable into the 12Volt compressor and wired it through the pressure switch, at the minimum setting it cuts in at 50PSI and out at 90PSI. There is a bolt under the cover to adjust the cut out pressure.
Anyway, consider using one of these, mine works well and for $75 ( a busted display one, normally $99) I have a tank, pressure switch, relief valve, regulator etc. Everything I needed for the whole job but a few air fittings.
