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

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

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.

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

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

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.
