Product Beschrijving

This melt-blown polypropylene cartridge uses a graded-density process: fibers are denser toward the core and more open at the outer layer, so larger particles are captured first and finer particles inside. The result is higher dirt-holding capacity, lower pressure drop and longer service life compared with single-density filters.This 5 micron 20 inch pp filter uses graded-density melt-blown media to capture coarse-to-fine particles with lower initial pressure drop.

When staged with carbon and RO, a 5 micron 20 inch pp filter protects downstream elements and extends service intervals.

It is commonly installed as a pre-filter for reverse osmosis, whole-house systems and industrial process lines to protect downstream carbon filters, softeners and RO membranes. The 5 µm nominal rating is a balanced choice for general sediment control and turbidity reduction; other ratings are available to match feed quality and target protection.

  • 100% polypropylene media — no binders, adhesives or additives
  • Low fiber release and chemical compatibility across typical pH ranges
  • Double open end (DOE) standard; fits most 2.5″ x 20″ housings
  • Recommended change-out at ΔP ≈ 0.1 MPa (≈15 psi) or by outlet turbidity

FAQ

De levensduur van een omgekeerd osmose systeem hangt af van de waterkwaliteit en het onderhoud. Het membraan gaat meestal 2-3 jaar mee, terwijl het systeem zelf meer dan 10 jaar kan meegaan als het goed onderhouden wordt.

Ja, al onze systemen zijn volledig aanpasbaar. We analyseren uw waterrapport en toepassingsbehoeften voordat we oplossingen op maat bieden.

Onze producten voldoen aan CE, ISO 9001 en kunnen op verzoek worden ontworpen om te voldoen aan specifieke regionale voorschriften of industrienormen.

Standaardsystemen worden binnen 7-15 dagen verzonden. Voor aangepaste bestellingen kan de levertijd oplopen tot 20-25 dagen, afhankelijk van de complexiteit.

Ja. We bieden volledige technische documentatie, begeleiding op afstand via video en kunnen op verzoek technici internationaal sturen.

Onze offerte omvat het volledige RO-systeem, het bedieningspaneel, de pompen, de voorbehandelingsunits en alle benodigde appendages. Installatiegereedschap en reserveonderdelen kunnen op verzoek worden meegeleverd.
