How a CO2 Scrubber Works. ... Air polluted with carbon dioxide is pumped into the CO2 scrubber. The air comes into contact with an ion exchange resin, which attracts the carbon dioxide molecules. The cleaned air is then pumped out of the CO2 scrubber.
Can scrubbers remove CO2?
A carbon dioxide scrubber is a piece of equipment that absorbs carbon dioxide (CO2). It is used to treat exhaust gases from industrial plants or from exhaled air in life support systems such as rebreathers or in spacecraft, submersible craft or airtight chambers.
