Device for reduction of pollutant concentration in printing machines, has visible light or ultraviolet radiation emitting radiation source in processing area, and rigidly arranged machine parts has photo-catalytically active coating

摘要

The device has visible light or ultraviolet radiation emitting radiation source (6) in a processing area (1). The rigidly arranged machine parts have a photo-catalytically active coating (3), which decompose organic pollutants during radiation. The photo-catalytically active coating consists of an oxide semiconductor material. The photo-catalytically active coating contains titanium dioxide in anatase form.
