PP polypropylene filters are used for prefiltration and fine clarifying filtration of liquids with high level of particle retention for reduction of loading on final membrane filters.
Features and advantages
- Biologically inert.
- Wide chemical compatibility and thermal stability.
- High filtration flow rate.
- High retentive capacity.
PP prefilters are used for prefiltration and bioburden reduction of:
- biological fluids;
- pharmaceuticals;
- solutions in a wide pH range;
- for air and gas filtration.
Material
Polypropylene non-woven material.
