The Oxygen Sealer is a machine added by Galacticraft. Its purpose is to seal and pressurize an enclosed area so the player may breathe without breathing equipment. bug: when you have diagonal blocks on certain technic modpacks does not work.
First get an Oxygen Collector up and running, then connect it to the right side of an oxygen sealer (all pipes through walls must use sealable pipes to keep the room sealed) and place a battery in the sealer or supply it with energy on the right side, then right click the sealer and click enable seal, the area must be completely closed off or have the doorways sealed with an Airlock doorway for the oxygen to seal. The Oxygen Sealer & Collector should be placed on a floor or wall to function properly. Varying amounts of oxygen input will be required to seal an area based on the volume to be sealed. The vent of the sealer must be exposed to the air or it will not work. If it not sealed or It's large area , the GUI will say Area too large/Unseal
One sealer can seal roughly 800 blocks of space. Multiple Oxygen Sealers may be required if the area is large enough. If your area requires multiple Oxygen Sealers, you don't need to spread them out throughout the area, they can be next to each other and still seal the entire area.
Torches will burn out if there is no oxygen, and they'll reignite when oxygen is restored.
WARNING: Certain blocks and objects are not airtight, and therefore will not create an enclosed space that can be sealed!
