Econe - Polyethersulfone (PES) Filter Cartridge
A PES filter cartridge is a pleated filtration element made from hydrophilic polyethersulfone (PES) membrane, designed for high-purity liquid filtration. PES membrane filters are widely recognized for their high flow rates, low protein binding, and excellent microbial retention efficiency.
-
Sterile-Grade Filtration: PES (Polyethersulfone) membrane filter cartridges are ideal for critical applications like pharmaceuticals, biotech, and laboratory filtration.
-
Hydrophilic Membrane: Our PES filters require no pre-wetting and offer fast wettability, reducing downtime in sterile filtration systems.
-
Excellent Flow Rate: Designed with uniform pore structure for low pressure drop and high throughput.
-
Broad Chemical Compatibility: Resistant to a wide range of solvents, making them suitable for complex liquid filtration processes.
-
Certified Quality: Manufactured in ISO-certified cleanrooms using FDA-compliant materials. Full traceability and documentation available.
What is PES Filter Cartridge
These cartridges are engineered to remove bacteria, particles, and other impurities from fluids in sensitive applications such as pharmaceuticals, laboratory processes, food & beverage production, and medical device manufacturing. Unlike PTFE or PVDF membranes, PES filters do not require pre-wetting, which enhances operational efficiency and cost savings.
The pleated design increases surface area, extending filter life and reducing frequency of replacement. They are typically used as final-stage filters in critical liquid processing systems, especially where sterility and consistency are essential.
Available in various micron ratings such as 0.1μm, 0.2μm, and 0.45μm, PES filter cartridges are compatible with most industry-standard housings, including 222 and 226 end caps. Whether for small lab systems or industrial-scale sterile production, PES pleated filters provide reliable and repeatable performance.
