Product Overview

The PP melt blown filter cartridge is a depth filter. It originates from polypropylene(PP) pellets, which are melted and extruded through precise nozzles. The polypropylene (PP) fibers are melt-blown around a core without chemical adhesives. The randomly distributed fibers form a three-dimensional micro-porous structure, enabling surface, depth, and coarse filtration simultaneously.

With its gradually densified pore structure, this filter delivers large dirt-holding capacity, high filtration accuracy, and low differential pressure. It efficiently removes suspended matter, particulates, rust, and other impurities, ensuring reliable performance and long service life.

Key Features

Gradient Density Structure: Optimized dirt-holding capacity with gradual pore size reduction.
Strengthened Fiber Surface: Prevents fiber shedding during operation.
High Filtration Accuracy: Superfine PP fibers for precise filtration.
Corrosion Resistance: Made from 100% pure polypropylene.
Expanded Filtration Area: Groove or grain surface design increases effective filtration area.
