Product Description

The extra-large UV disinfection filter combo is great for treatment of larger homes or small commercial applications where there is less demand on water use. With ultimate quality in mind, it comes complete with a WRAS approved Atlas L79 UV unit and a filtration system that includes a 20″ large diameter filter housing along with a 4 pack of 20″ large diameter 25µ UV filter cartridge, so you will have everything you need to get started.

As the table below shows, this package is suited for 5 bedroom + properties where the peak water demand is unlikely to exceed 79l/min or 4.7m3/hr throughout the property. The extra-large UV filter unit provides a dosage of 30 mJ/cm² (at end of its 1-year lamp life). This UV disinfection unit is manufactured with domestic drinking water treatment in mind and though you can use it for an aquarium, the UV dose will be higher than you would normally need.   Please see the technical details below for further information.

The highly efficient ballast provides a visual display for information including remaining UV lamp life and total days of operation using the full-colour LCD display. Its output is multi-voltage (100-240V. 50-60 Hz.) so it can be used on a mains supply or with any true sine wave generator.
