Unique pellet shape
The unique hemispherical pellet shape allows a low breathing resistance and thereby provides longer usage periods.

Reproducible absorption
The uniform shape ensures an even filling of the cartridge resulting in reproducible CO2 absorption and prevents channelling in the cartridge.

Indicator
The Drägersorb 400 ind and the Drägersorb 400 ind S feature a color indicator. The indicator will change with e.g. CO2 from white to violet, the external signal for the
replacement of soda lime.

High CO2 absorption capacity
The extensive inner surface of the soda lime pellet guarantees a high CO2 absorption capacity.

High resistance to abrasion
The unique hemispherical pellet shape has a high resistance to abrasion and thereby reduces dust formation.

Higher water content
The Drägersorb 400 S and the Drägersorb 400 ind S offer a higher water content. Dräger is the only company to produce soda lime with higher water content especially for room air application and whose filtering function lasts longer under these conditions than conventional soda lime products.

Typical applications
ventilation filter for waste water plants
supply air filter for cooling water circulations in power plants (deionised water)
shelter and rescue rooms in mining
rescue trains
