UV light serves for the photo-oxidation of odours. Many malodorous VOC molecules can be oxidised by means of UV light. The result is a significant improvement of the odour situation.

UV light needs like activated carbon a good pre-separation of dust or smoke in order to ensure that its effects are complete. After the UV oxidation state a reaction section is necessary for completing the oxidation process.

UV light tubes are ideally suitable for high exhaust air temperatures from for example frying plants and convince by their long durability of 8000 – 10000 hours.
