Thread: air tank

A Landrover to bolt it to.

(sorry couldn't resist)



I would think you'd need a pressure cut out switch so when the pressure in the tank reached a certain point, the compressor turned off.

I'm sure someone else can elaborate.

I never said what I was going to bolt it too anyways

sheesh one in every crowd

Hi Bigbugga
The common 9lt water fire extinguishers are pretty good,alleady have a car air valve to presurize and are rated 120psi+(you charge them to 120psi so they are probably tested to near twice that)
The cheapest place to buy them is Elders/Wesfarmers as farmers buy ****loads of them for harvest etc as they are mandantory on any machine working in a paddock at harvest.They are the most efficient bit of gear when a farm machine starts a fire,point and squirt high pressure water.Best bit is you fill em up with water,plug the compressor in and you are ready to go again.
Easy enough to get fittings from an Enzed type shop to plumb up to your compressor.
Goodluck

You will need:
Air inlet from compressor, weld in a female thread of the size you require

Another female thread welded in to attach the pressure cutout switch which of course will be wired back to your compressor

And a third female thread to attach a small pressure relief valve set to your maximum operating pressure in case the pressure switch fails and puts the system under overload

Then last but the most important another outlet to deliver the air to where ever you want.

Now, with a little thought and judicious piping you can accomodate the last three in a single header so ultimately you only need to weld in 2 connections.

Hope this makes sense........it's friday night and the red is flowing

This idea worries me a lot!!! 8O

Not to sure I'd skimp on the $$$ for proper parts.

Just be SAFE... compressed air is very dangerous....

Drop into your friendly Opposite Lock store and pick up a proper pressure switch. This will allow you to set the max pressure and the cut in pressure.

Not cheap but for safety's sake, as mentioned above worth the dollars.

I have mine set to 60psi max and cuts in at 45psi. My tank also came from OL, (11litres) and is fitted up under the LH sill on the fender.
Fittings are 1/4" bsp.

Air in, and also tee'd into the pressure switch and pressure gauge.

Air out, to a standard airline quick disconnect outlet

Drain (blow down valve in bottom of tank).

Thanks all.

I feel a lot more informed now, and wont feel like such a fool when asking for what I need.
