25W UV Ultra Violet Water Filter – 18 Litres Per Minute UV Water Treatment

25W UV Ultra Violet Water Filter – 18 Litres Per Minute – UV Water Treatment System

The 25W Ultra Violet UV system is ideal for point of entry or point of use applications, commonly used as part of a private water supply setup 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 18 litres per minute flow rate this system is suitable for use as a whole house UV system to treat water for small/average homes where the flow rate will not exceed 45LPM. Ideal for use on private water supplies, well water treatment, bore holes, motorhomes, static homes, and so on.

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 whole house UV pre filter system for this.
