Air respirator

May I ask everyone, why does the air reservoir of a breathing apparatus need to be turned upside down when in use, with the outlet facing downward?

The second floor is the correct choice; the users should adjust the air volume as needed based on the conditions on site

1. First of all, the air inside is not liquefied; it remains in gaseous form, so there is no problem with the outlet being at the bottom. 2. It is convenient to turn it on and off by oneself when carried on the back.

Look and see if it’s convenient for you to use it with it facing up

What was said on the 2nd floor is correct – put it up there, will you be able to get it?
