Yes, capacity in the sense of more pressure. Allthough the cylinder capacity is, lets say 1.1 litre, there will be 50% more air because of the higher pressure.
Iv got a 4500 max flo just need a bottle. I used to own a 3000 steel tank but was too heavy. Do you kno anyone selling a 4500 bottle prefreably 1.1L in size?
ryder,
i don't think anyone has actually pointed this out to you, but you can fill a 4500 bottle up with a 3000 supply so you can use it at your local site,
"but you cannot take a 3000 bottle and fill with a 4500 supply"
as it will go bang and blow your head off !
Just thought i'd mention it
