Cintropur UV 4100 lamp 40 W is an original UV-C replacement lamp for Cintropur UV 4100 and TRIO-UV 4100. It delivers a stable main line of 253.7 nm, which is the standard wavelength for microbiological water treatment, and has been developed for chemical-free disinfection of pre-filtered water. This is a spare part for planned annual maintenance when you want to maintain documented bacterial hygiene performance in a point-of-entry UV system for housing, well water or rainwater systems.

As an original part from Airwatec, the lamp is adapted to ballast, base and quartz sleeve in the UV 4100 series. Compared to non-original lamps, the correct fit, stable ignition and predictable UV dose are important for safe operation and correct functioning of the system. The UV unit should be used as the last step in the line after mechanical pre-filtration and possibly activated carbon, because turbidity, particles and coatings on the quartz sleeve can reduce the effect of the UV disinfection.

• Original 40 W low-pressure UV-C lamp for Cintropur UV 4100 and TRIO-UV 4100
• Stable UV wavelength of 253.7 nm for effective inactivation of bacteria, viruses and other microorganisms
• Chemical-free water treatment that does not change the taste or smell of the water
• Recommended lamp replacement once per year in normal 24/7 operation
• Designed for interaction with the system's ballast, safety function and quartz sleeve
• Suitable for domestic use, well water, rainwater and other installations with pre-filtered water

UV-C works by damaging DNA and RNA in microorganisms so that they cannot reproduce. In practice, this means a hygienic barrier without the addition of chemicals and without the formation of by-products from the UV process itself when the system is correctly dimensioned. In a home with its own well, this can be the last hygiene step before the water is distributed to the kitchen, bathroom and shower. In systems for rainwater or technical water, the lamp contributes to better microbiological control when the water has first been filtered for particles.

To achieve the expected performance, the water must be clear enough for UV light to penetrate, and the chemical quality must be within relevant drinking water standards if the water is to be classified as drinking water. It is therefore recommended to check pre-filtration, flow rate, quartz sleeve and service interval as part of a fixed maintenance plan. The quartz sleeve should be cleaned gently when necessary and considered replaced after several years of operation, often around five years depending on water quality and load.

This lamp is relevant for you who use Cintropur as a water filter and UV treatment in homes, smaller commercial buildings or other point-of-entry solutions where safe water supply is important. In contrast to a normal filter cartridge that removes particles or improves taste, the UV lamp is the component responsible for the disinfection step itself. Therefore, the lamp should be changed as a preventive measure even if it still lights up, since the UV effect decreases over time.

The product is supported by manufacturer data and practices described in, among others, Cintropur's installation and maintenance manuals, NSF/ANSI 55 for UV systems, WHO guidelines for drinking water and EPA guidance for UV disinfection. Use and installation must take place in accordance with the manufacturer's instructions, and components that require professional assembly should be installed by a qualified installer. This is a precise choice for those who want stable water hygiene, documentable specifications and the correct spare part for the Cintropur UV 4100 series.
