PP‑Melt‑Blown 20‑Inch Spun Melt Blown Filter Cartridge For Water Pre‑Filtration

For small‑medium water‑treatment and food‑beverage pre‑treatment projects, PP‑Melt‑Blown 20‑inch melt blown filter cartridge is cost‑effective pp melt blown filter. This spun filter cartridge adopts gradient depth‑type polypropylene melt‑blown fiber structure. As typical depth filter cartridge, outer layer captures large particles, inner fine fiber traps tiny impurities, good dirt‑holding performance for water pre‑filtration cartridge. It fits standard 20‑inch filter housing, commonly used for RO pre‑filtration, drinking water equipment, food and beverage production water pre‑processing.

Depth‑Type Filtration Principle Of Melt Blown Filter Cartridge

Raw water flows from outer surface gradually penetrate into inner core of 20‑inch pp melt blown filter. Gradient fiber density of this spun filter cartridge realizes step‑by‑step interception for different‑size solid particles. Large‑size impurity trapped in outer coarse fiber layer; fine micron‑sized pollutants intercepted in inner dense fiber layer. Clean water flows into central core pipe. This depth filter cartridge avoids fast surface‑blocking, extends service life for water pre‑filtration cartridge.
