Description
Accessories: Pre-filter for Alb Filter® Duo Nano tap filter
The pre-filter extension for your Alb Filter Duo Nano tap filter to protect the Nano filter cartridge.
Effective against coarse dirt such as pipe deposits, sediment, rust, sand and much more.
Why can the pre-filter be useful?
In certain installation situations (old buildings, etc.), pipe deposits, sand, sediment, rust, particles or suspended matter can clog the individual hollow fiber membranes of the Nano cartridge much more quickly and reduce the service life of the filter cartridge. The replaceable 40 µm pre-filter cap (pat.) ensures coarse pre-filtration and increases the service life.
How is the pre-filter used?
The pre-filter is placed directly over the inlet opening of the Nano cartridge. See picture.
