This system turns compressed air into safe breathing air

By Mary Page Bailey and Gerald Ondrey |

The Ultrapure Smart ALG breathing-air system (photo) processes compressed air into safe breathing air, using a sequence of filtration and adsorption operations. A first stage removes condensate and particles from compressed air by an UltraPleat coalescence filter. Air is then guided through a desiccant cartridge to remove water and CO2. Adsorption and regeneration alternate between two cartridges. Traces of CO2, SO2 and NOx are removed by adsorption, and CO is catalytically converted. A final filtration removes particles down to 0.01µm, producing highly purified breathing air. The system is suitable for applications involving exposure to dust or solvents, and in the chemical and pharmaceutical industries where gases and contaminated aerosols are involved. — Donaldson Filtration Deutschland GmbH, Haan, Germany
