Pleated Membrane Cartridges
PTFE, PVDF, PES, Nylon, PP, and Glass Fiber membranes. Pleated structure maximizes filtration area. Ratings from 0.1 to 10 μm. Hot-melt welded end caps -- no adhesives.
Pleated filter cartridge supply from Shanghai, China — compare membrane and depth-media options against fluid, retention and validation requirements.
Pleated Membrane Cartridges
JINLV pleated membrane cartridges are constructed using imported membrane materials bonded to polypropylene or reinforced end caps via thermal welding -- no adhesives, no migration risk. The pleated geometry delivers 3-5x the filtration surface area of a flat-disc element of equivalent footprint, extending service life and reducing replacement frequency. Membrane options span hydrophobic PTFE (for gas and solvent filtration), hydrophilic PTFE and PVDF (for aqueous pharmaceutical streams), PES and Nylon (for bioprocess and fine chemical applications), PP micron (for general industrial liquid filtration), and glass fiber (for high-viscosity or high-temperature streams). All cartridges are integrity-testable by bubble point or diffusion flow methods. Standard connections: 222, 226, 220, DOE, and custom. Lengths: 10 in, 20 in, 30 in, 40 in.
Confirm duty before comparing membrane media
Wettability is only the starting point. Media concentration, temperature, pore size, sterilization and integrity testing define the final construction.
Preliminary membrane: PES / Nylon hydrophilic Phase: liquid Media: aqueous Temperature: 25 °C Pore rating: 0.22 μm Sterilization: none Integrity test: bubble End connection: 222
Filter membrane materials by process requirements
Choose the phase, process priority, wetting requirement, and filtration stage. The tool shows exact and conditional matches; final selection still requires compatibility and sample validation.
| Membrane material | Wettability | Typical applications | Compatibility note | Match | |
|---|---|---|---|---|---|
| PES (Polyethersulfone) | hydrophilic | Aqueous bioprocess, pharmaceutical, and fine liquid filtration | Confirm against the actual medium and concentration | — | View product |
| PTFE (Hydrophobic) | hydrophobic | Air, gas, venting, and compatible non-aqueous media | High; compatibility confirmation still required | — | View product |
| PTFE (Hydrophilic) | hydrophilic | Aggressive aqueous chemicals, acids, bases, and compatible solvents | High; verify temperature, concentration, and seals | — | View product |
| PVDF (Hydrophobic) | hydrophobic | Compatible gases, solvents, and chemical process streams | Very good within the verified compatibility range | — | View product |
| PVDF (Hydrophilic) | hydrophilic | Aqueous bioprocess, protein-containing, and chemical liquids | Very good; verify adsorption and extractables requirements | — | View product |
| Nylon (Polyamide) | hydrophilic | General aqueous, alcohol-based, food, beverage, and fine chemical liquids | Good for selected media; acids require special review | — | View product |
| PP (Polypropylene) | hydrophobic | General industrial liquids, water treatment, and economical clarification | Broad general compatibility; verify oxidizers and temperature | — | View product |
| Glass Fiber (GF) | hydrophilic | High-viscosity liquids, colloids, and high-load prefiltration | Medium-dependent; hydrofluoric acid is unsuitable | — | View product |

Recommended Membrane Product Families
Buying pleated membrane cartridges: define the duty and required evidence
This category includes membrane options alongside pleated PP and glass-fiber media. Choose a product family by the filtration task; not every pleated cartridge is a sterilizing-grade membrane filter.
- 01
Specify liquid or gas, chemical composition/concentration, temperature, wettability and retention target. Review the full assembly, including supports and seals, for compatibility.
- 02
Confirm length, end connection, seal material, flow and pressure conditions. Separate normal operation from cleaning or sterilization conditions and intended cycles.
- 03
List required application documents and acceptance tests before quotation. Confirm the exact model, quantity, destination, sample evaluation and lead time rather than relying on a generic membrane name.
Check evidence before approval
A 0.22 μm label or an ISO 9001 certificate does not by itself establish sterilizing-grade performance. For critical service, confirm applicable retention validation, integrity-test method/limits and material documentation for the actual configuration before approval.
Is selecting PES, PTFE or PVDF enough to place an order?
No. Confirm the grade, wettability, retention definition, dimensions, seals and operating/cleaning duty. Where required validation is unavailable, keep the application pending rather than assuming approval.
