Photo catalytic filter for processing and purifying air in ventilation system, has external frames sliding along central frame, supporting UV lamps, to adjust opening, where central frame is intercalated between external frames

摘要

The filter has two external frames (1), where each external frame supports a photo catalytic media (2) comprising an activated carbon face and a braided face with a titanium dioxide deposit. The external frames slide along a central frame (3), supporting UV lamps (5), to adjust an opening (4). The central frame is intercalated between the external frames, and a dimension of the external frames is lower than that of the central frame.
