I'd be impressed if there's a cheaper thing to fill into a can of compressed air then regular air.

My understanding is that this is because a typical compressed air can could not actually withstand the pressured required to hold normal air, compressed.
- jerzyt 6y agoCompressed air is definitely cheaper than any other gas you could use, but you can't liquefy air at room temperature, at least not reasonably. As result, a can of compressed air would have very low capacity compared to a gas which can be liquefied at room temp. A gas like propane for your BBQ liquefies at room temp, and once it's liquid you can put a lot of it into a cylinder without increasing the pressure. That's why compressed air is not used in the spray cans.
