12W UV Ultra Violet Water Filter – 4 Litres Per Minute UV Water Treatment System

12W UV Ultra Violet Water Filter – 4 Litres Per Minute – UV Water Treatment System

The 12W Ultra Violet UV water filter is ideal for point of use applications to help protect against bacteria & microorganisms. The system comprises of a 304 grade stainless steel chamber containing a UV-C germicidal lamp. As water flows through the system microorganisms are exposed to the UV light within the chamber.

At up to 4 litres per minute flow rate this system is suitable for use with under sink water filters and water dispensers. The system is supplied with fittings to connect directly to 1/4″ outer diameter water pipe, so that it can be connected easily in-line with an existing filter system (adapters are available for other tube sizes).

The UV lamp / bulb will last for up to approximately 1 year between changes, with changing recommended after 8000 hours – note bulb will remain lit beyond this but will loose effectiveness. The power supply transformer features a visual indicator to show when the bulb is lit or not in the rare event of bulb failure, for complete peace of mind it is recommended to check this regularly when in use.

Note: It is always recommended to choose a lamp with higher capacity than anticipated to account for variances in water conditions and lamp life. It is recommended that the UV system is installed after at least a 5 micron filter as sediment particles may shadow microorganisms from the UV light. We recommend installing after our “small UV lamp sediment pre-filter system” for this.
