HYDRA RAINMASTER DUO RLH CB 3/4” - Well Water Filter Household Water Filter

Dual Filter Housing with One-Piece Head

This filtration system treats water efficiently at high concentrations, reduces iron content, and filters out contaminants and fine particles from the water.

Innovative backwash system with spring-mounted filter cartridge. When the flush valve is opened, the pressure drop pulls the cartridge downward, cleaning it internally as well. A minimum pressure of 1.8 bar is required to ensure backwashing.

Includes hose connector and drain funnel with backflow protection according to UNI EN 1717-11/2002

This works through the self-cleaning/backwash pre-filter with 90 microns, a pre-filter with 25 microns, and a final water treatment CARBON cartridge.

The filter cleans the water down to 10 microns.
