random fire extinguisher question.

[mysterious_rider]

Ok this is random, but why are the tanks only classed as '6Litres' When they are like twice the size of a jerry can, and look capable of taking about 12 easily.

Is half of it not used or something?

planning on using one as a tank. Cheers.

normally the top half of the cylinder is where theres a charge that expands to pressurise the contents
I remember stripping the ones in our work to have the charges replaced years ago, something like this

Ah damnit. I appreciate the info though!

If I did choose these as a tank, It won't be easy. I'll have to nip the top off, and run some drill holes around that plating so fuel can go through and make use of all of the space.

Then just reweld it all.

Cheers.

it can be done, I seen one used as a tank on a biker build
they took an extinguisher and made a petrol tank from it

dude,just get an AFFF extinguisher (9 litre one should be big enough) the bottle itself is pretty much the same inside as out, no funny workings inside

Hm Couldnt find any cheap of those afff ones, so got myself some water extinguishers.

It has to be cut and welded anyway, so I'll just buy a long drill piece attachment and just put a load of holes in the plate in the middle.

Will also remove the gas canister. I wonder how its held in there... Welded?

hardest part will be welding it all up afterwards!!

The charge is just screwed in i think so they can be serviced/recharged every few years

Can you do pics of the completed item? Would be interesting to see!

^ Fantastic. I'll unscrew the top and run various drill holes through that plate. Pretty unfortunate that stupid canister will be taking up space, I will try and remove/puncture however.

Plan of action is cut a hole in the top for a cap, if the tanks are alloy, I shall cut up a pitbike tank, and use the top half with the cap and pop rivet it into the tank with an O ring to seal it. And two universal taps underneath (normal and reserve).

If tank is steel I should imagine I'll get it welded, but I want rat style so pop rivets sounds good.

I'll be running two of these side by side.

Cheers for the help. (I'll be throwing up a project thread with pics in soon anyway)

If you're serious about fire, fit one of these to your garage:
