extinguisher bottle as an air tank... how do i set it up?

[rustynuts]

I dont know what the problem with using an extinguisher Ive been using one in both of my landcruisers for 3 years without any dramas.
Heres a few stats to chew over:

9kg extinguisher tested to 2500 kpa
1.5 - 9 kg around 2000 kpa

Thats approx. 280 psi

These are tested presures not the charge presure (big difference). Charge pessure is alot lower. These containers work incredibly well.
If your worried about whats in the container wash it.

If you want to get one go to a place that services extinguishers and ask for one of the discarded ones, you never know your luck. I know we have heaps laying around that wont be used again. Try Wormald or chub

Cheers Russ

For all those who don't believe it 2 x maxairs into a 20ltr tank keeps a rattle gun going non stop

I've just got a 9L extinguisher that Im modding for an air tank. Drilled a hole in the base for the drain and welded a socket onto it.
Now the next problem is finding a suitable place to mount it and welding on some brackets

i got a 9kg fire ext tank and it says to recharge to put in water then charge to 620 kpa about 89psi and as far as i know all pressure vessels are tested to 3 times the working pressure thats about 1860kpa test or 269psi all i did was cable tied the handle on and unscrewed the hose and put the air outlet into that then unscrewed the tyre valve and got a fitting that went in there all good

nothin wrong wit cable ties to buy fittings and a manifold to remove handle setup would cost well over $25

this is true.

IMHO i would just use black steel fittings and weld them into the tank.

it would be different if you were using the tank simply as an added air receiver.

if you want qaulity, cost is priceless..

I pulled the handle and fittings apart. Blocked 2 of them off with bolts & used the other for the inlet line. Hasn't had a drama yet...

greetings all

i am a long time reader but thought i would make a post as i have been following this thread for some time

the beer keg looks interesting to me

i am now ready to fit an air tank under my trailer & want to keep it as small as possiable in Diameter but can be as long as 1800mm

anybody have any ideas were i may be able to find an alloy tank or something that is light weight
