Smaller version of the 3M Scott Air-Pak?

on-demand air. I'm looking to accomplish the same idea, contained breathing, but in a smaller apparatus. I have no idea whom to ask about something like this but this resembles scuba so much I figured it'd be worth a shot.

Are there systems like this out there but smaller? Thanks.

Sorry, it wouldn't let me edit. The text should have been...

Pictured below is the 3M Scott Air-Pak used by fire fighters in compromised environments. The tank is just compressed air and supplies a face mask with 30 minutes of on-demand air. I'm looking to accomplish the same idea, contained breathing, but in a smaller apparatus. I have no idea whom to ask about something like this but this resembles scuba so much I figured it'd be worth a shot.

How about a pony bottle and harness? You nave to supply a regulator.
