Product Features & Advantages
Broad Chemical Compatibility
Polypropylene media is suitable for filtration of many acidic, alkaline, aqueous, alcoholic, and selected solvent-based fluids. This allows the capsule to handle process streams where chemical exposure limits the choice of filtration materials.
Integrated One-Piece Construction
The capsule features an integrated, one-piece polypropylene construction, with the main fluid-contact components formed into a unified filtration assembly. Thermal welding is used instead of adhesive bonding, creating an adhesive-free filtration path that helps reduce potential contamination from bonding materials.
High-Capacity Prefiltration with PP Depth Media
The graded PP depth-media structure captures suspended particles through the depth of the filter rather than relying only on surface retention. This gives the capsule a specific role in particulate prefiltration and clarification before downstream fine filtration.
Controlled Particle Retention
The PP microporous membrane provides controlled particle retention for applications requiring a tighter filtration barrier than PP depth media. This allows the capsule to address fine-particle filtration requirements while retaining the material compatibility of polypropylene.

FAQ
Q1: What is the difference between PP depth media and PP membrane filtration?
PP depth media uses a graded fiber structure to retain particles throughout the media depth and is mainly used for prefiltration and clarification. PP membrane filtration uses a microporous membrane for finer particle retention at a defined pore rating.
Q2: Can the capsule filter be backwashed?
No. The capsule is designed for single-use operation and is not intended for backwashing or regeneration. Replace the complete capsule when the applicable pressure-differential limit is reached.
Q3: Is polypropylene compatible with all chemicals?
No. PP is compatible with many acidic, alkaline, aqueous, alcoholic, and selected solvent-based fluids, but compatibility must be verified against the specific chemical and process conditions. Strong oxidizing agents and concentrated aromatic solvents require particular verification.
Q4: How should I choose between PP depth media and PP membrane?
Use PP depth media for particulate prefiltration or clarification, particularly when the incoming fluid has a higher solids load. Use the PP membrane configuration when finer particle filtration at a defined pore rating is required.
Q5: Can the Polypropylene Media Capsule Filter be customized, and what information is required?
Yes. OEM/ODM customization is available for the product. Buyers should provide the process fluid, required filtration rating, expected particle load, flow rate, operating temperature and pressure, connection requirements, and preferred inlet/outlet configuration. These details help determine the appropriate PP depth media or membrane configuration and capsule specifications.
