The SFPP series filter cartridge is made of high-purity food-grade polypropylene particles as raw material. It is a cylindrical microporous deep-layer filter cartridge formed through melting, spraying, traction, and receiving. The fiber threads have a multilayer gradient structure in three-dimensional space, with coarse and loose outer fibers and fine and tight inner fibers. Particle interception is achieved through layer-by-layer retention, resulting in stable retention effect and high filtration accuracy. It is a filter element with extremely low cost.
Product classification: regular type -SFPP; polypropylene core - GSFPP; polypropylene outer housing - WGSFPP.
Typical Applications:
- Security filtration in the process of pure water production
- Pre-filtration for injections, medicinal liquids, and bottle-washing water
- Pre-filtration in precision filtration processes
- Impurity removal filtration for chemical reagents
- Clarification filtration for acid and alkaline fluids
Product Features:
- Low cost, economical operation
- Stable retention effect
- Excellent chemical stability
- High dirt holding capacity, long service life
- Can be back-flushed, scrubbed, and reused
- High mechanical strength, fibers are not easily detached
