20μM 40" High Flow Filter Cartridge Polypropylene Filter Cartridge
Description of Pharmaceutical water prefiltration
WECHANGE PP membrane filters are high efficiency depth type filters
constructed entirely of chemically resistant polypropylene. They
are economical, premium quality products that deliver consistently
high filtration efficiency, superior flow rates, substantial dirt
holding capacity, and exceptionally long service life.
All-polypropylene construction makes it a cost-effective choice for
clarification and prefiltration applications.
WECHANGE PP membrane filters are ideal for clarification,
polishing, bioburden reduction and prefiltration applications. It
is compatible with a wide range of chemicals and cleaning agents.
