Breath mask/Legends

A breath mask was an apparatus that was strapped to the face. It usually had a hose to a filter or air canister, which supplied the wearer with fresh, breathable air.

Breath masks also safeguarded the wearer from minor differences in atmospheric pressure. Typical air canisters provided one hour of breathable atmosphere before replacement of the canister was required. The typical breath mask weighed roughly 1.5 kilograms. These masks offered no protection from extreme temperatures or a hard vacuum.

The content of the canisters&mdash;also known as air-tanks or breather packs &mdash;varied depending on what species was wearing it. As a member of the breather Gand subspecies, Zuckuss wore a respirator, since he needed to breathe ammonia, as oxygen atmospheres were poisonous to him. He kept the ammonia-filled canisters to his breath mask on his person. The tubes of his respirator were connected to a gas-processing unit, which he carried on his back.

All Kel Dor who left Dorin wore antiox breath masks because they needed helium and their own native gas, as oxygen was poisonous to them as well. The Ubese also wore breath masks. Breath canisters typically weighed about 1 kilogram and cost 25 credits. The breath masks also varied in cost, but from 32 BBY to 8 ABY, most models were available for 200 credits.

Breath masks could be built into armor. The most famous example of this was Darth Vader's armor. Breath masks were also used to supply breathing gas to a patient while submerged in a bacta tank.
