Hello,

I want to install an oxygen bottle in my ASW20. I haven't found any documentation on what size bottle should be installed. I tried a search on this site and there are loads of posts regarding oxygen but I couldn't get them to open. Anyone know why? Anyone have any information on the size of oxygen bottle to use in an ASW 20?

Thanks,

Deming

You need a steel (not aluminum) E size bottle. These may vary a little in OD and smaller is better (4.18" is the magic number iirc). The aluminum E size bottles are too big.

Something like this:
