Spherasorb 408 Sodalime
Spherasorb 408 is a spherical shaped Soda Lime, available as NI (non-indicating) or WV (indicating). Soda Lime’s efficiency at removing Carbon Dioxide from air, leaving Oxygen behind, makes it a vital part of CO2 Scrubbers and rebreathing systems.
Military, Diving, and Medical applications (Conditions where keeping air breathable when circulation with outside air is impossible).
Spherasorb 408 is comprised of 3 mm cylindrical granules, produced to achieve maximum CO2 absorption. The combination of the spherical shape and particle size (4 to 8 mesh) leads to good packing within scrubbers and rebreathers, generating very low dust levels and relatively low breathing resistance. Spherasorb 408 has been tested to, and conforms to, the STANAG 1411 and EN14143 standards for rebreathers.
