Two-part UV-C emitter converting redundant active oxygen to oxygen. An excess concentration of ozone is excluded. For rooms with a capacity of up to 70 m³ ~ approx. 27 m² (the conversion to m² is based on the average ceiling height of 2.6 m).
After approx. 11,000 operating hours, the efficiency of the UV-C lamps is reduced slowly. The change of UV-C tubes is described in detail in the operating instructions and can be performed by oneself without problems. Any expensive maintenance of these units is NOT required.
