It's pumped in with an Air Compressor
people are not safe in space if there air tanks run out of oxygen because there is no air in space.
Air tanks were invented to hold compressed air.
they have air tanks in their space suits
Air tanks come from russian bollets made from solfer umonier
The air trapped in the hull (this includes the buoyancy tanks) make it lighter than the water it displaces. The buoyancy tanks surround the main hull (where the people and machinery are), and can be flooded to allow the ship to sink. Refilling them with air (from compressed air tanks) allows it to return to the surface.
The air tanks on a submarine are typically located in the ballast tanks, which are distributed throughout the submarine's hull. These tanks are used to adjust the submarine's buoyancy by filling or emptying them with air or water.
Air tanks, also known as compressed air tanks or cylinders. These are used to store air under high pressure for different applications. MasterAire stands on hi-tech infrastructure that includes core expertise in the air compressor industry. They are commonly used in scuba diving, firefighting, and industrial settings. The tanks are filled with compressed air and then used to provide a portable supply of air when needed. In scuba diving, for example, divers carry air tanks to breathe underwater. The pressure in the tank forces air through a regulator, which reduces the pressure to a breathable level. These tanks are usually made of steel or aluminum for durability.
people breath in space with air tanks installed in them Modern spacecraft also have air processing equipment to remove toxic waste products such as Carbon Dioxide and to add Oxygen so that the air can be re-used.
Nitrogen.
The submarine has scrubbers. They remove carbon dioxide from the air and break it down to release the oxygen back into the air. There are also a few tanks to supplement the oxygen content if necessary.
Firefighters typically get oxygen tanks from their fire department or fire station. These tanks are filled with compressed oxygen and are essential for providing breathable air to firefighters in hazardous or smoke-filled environments.
The air to replace the water in a submarine's ballast tanks typically comes from high-pressure air banks stored onboard the submarine. These air banks are filled with compressed air from the submarine's air compressors and are used to control the submarine's buoyancy by adjusting the amount of air in the ballast tanks.
