What is a PES Filter Cartridge?
A PES (Polyethersulfone) filter cartridge is a membrane-based filter widely used for precision liquid filtration.
Its asymmetric pore structure provides excellent flow rate, low protein binding, and high thermal resistance, making it ideal for biopharmaceuticals, microelectronics, and beverage sterilization.
Key Characteristics:
Asymmetric PES membrane structure
Hydrophilic surface (no pre-wetting required)
Wide chemical compatibility
Long service life and high dirt-holding capacity
Available in 0.1μm, 0.2μm, 0.45μm, 0.65μm pore sizes
Our Production Capabilities
We control every step of the manufacturing process — from membrane sourcing to final inspection.
Production Process Overview:
Raw material selection (high-quality PES membrane + polypropylene support layers)
Automatic pleating for uniform structure and high filtration area
Hot-melt welding to ensure 100% integrity and zero leakage
Integrity testing (bubble point test & pressure test)
Final assembly and packaging under cleanroom conditions
We maintain batch traceability for every filter cartridge to ensure full quality control.

Applications of PES Filter Cartridges
