The new compact drinking water filter with UV-C treatment WAF 20 from AFRISO (Germany) was designed as a simple and easy to fit filter for below worktop installation, providing clean and healthy drinking water. WAF 20 consists of a robust plastic housing with active carbon fine filter insert and stainless steel reactor housing (for the UV-C tube), a sturdy mounting bracket and the housing for the electronics. WAF 20 is installed just in front of the water withdrawal point. The incoming drinking water flows first through the active carbon filter and then passes the ultraviolet tube which kills reliably any micro-organisms present. Should an exchange of the UV-C tube be necessary, a visual and audible alarm is triggered. WAF 20 eliminates up to 99 % of all heavy metals, herbicides, pesticides, residual medicines, bacteria and viruses without forming any harmful by-products which contaminate the environment or are damaging to health. When using this filter, there is no danger of any chemical reaction in the preparation of food stuffs, drinks, essences, medicines or in the mixing of baby foods. The filter can, however, also be used for the manufacture of rinsing water or process water, water for agricultural use or in connection with decalcifying plants. WAF 20 has two G¼ connections and is suitable for a maximum flow rate of 300 l/h and an operating pressure up to 6 bar. WAF can be supplied with 230 VAC, using the mains adaptor provided, in the area of housing technology or with 12 VDC for camping, caravans or leisure boats (especially where drinking water is stored in vessels for longer periods of time).
