Air Scrubber | SafeRack's Industrial Index
Dry Scrubbers. Dry scrubbers are air pollution control devices that use a dry sorbent, usually in the form of a powder, to remove pollutants from exhaust gases. Dry scrubbers work by passing the polluted gas through a chamber where the sorbent comes into contact with the gas and binds with the pollutants.
