High Corrosion Resistance Self Cleaning Filter Working Principle For Sea Water Filtration
The filter can be set up for fully or semi-automatic or manual operation.
Internal scraping self-cleaning filter blends modern technology with simplicity to provide a versatile method of filtering your process fluids.
Working principle: liquid enters the filter body from inlet and flows through the filter element from inside to outside. Impurity is collected on the internal surface of the wedge wire element. The reducer motor drivers scraper blades to remove the impurity contiously. Cleaning takes place without interruption to flow by the rotation is deposited into the bottom of the filter body from where it can be periodically discharged automatically via the drain outlet.
