Donaldson Portable Air Filter

A portable filter box to remove particles and odours.

The Ultrapure ALG 20 is applied when the breathing air is contaminated by the working process itself, as for example during sandblasting, varnishing, paint production, in chemical industries, in plastics industries or working places where the air quality is impaired. 

If the compressed air is centrally pre-purified and carbon monoxide (CO) and carbon dioxide (CO2) concentration in the compressed air do not exist, the Ultrapure ALG 20 with its two respectively three filter stages is used as an additional solution for purification application.
