Re: Fire extinguishers as air tanks.

[M1S3RY]

Can you readily get a fitting that screws directly into the neck of a extinguisher, or do you need to get 2 seperate fittings, one to replace the pressure guage (Inlet) and one to replace the nozzle (Outlet)? And then secure the handle down.

Thanks for any info.

According to fitting people, fire extinguishers use "unique" fittings. Certainly the 9kg water extinguisher I have at home uses an unusual fitting.

My one has its valve built in to the main fitting so you can't just screw barbs onto the gauge/nozzle and call it good, unless you wire the valve open which all sounds a bit hack to me.

I went to Enzed and the guy recommended a small fire ex as a tank and said they have fittings to suit. I have one thats out of date so i will give it a go.

its been done before, but why not go to a truck wrecker and get a tank with pressure relief valve fitted for about $20-50

While this is prolly the best option for acquiring a tank, i have access to a 4.5kg fire extinguisher for free and wanted to try it for myself.

Ive never used one as an air tank , But we used to get the stainless ones
and remove the gauge and replace with a tube and tire valve ,

Unscrew the top fill with water ,replace and pump it up a bit with your car compressor and you have a bit of a presure cleaner .

We used them a bog hole events to clean the brakes ect before heading home .

Yes they do have unique fitttings i welded a BSP sleeve in the top of my 9kg tank to scew the inlet fitting in

You can get a 18l air tank from Bunnings for $39. I replaced the hose that comes with it with a nito fitting. Works great.
