PES Pleated Filter Cartridge Features
The naturally hydrophilic PES membrane combines high flow, uniform pore structure and reliable microbial retention for demanding fine-filtration processes.
High Flow, Low Pressure Drop
The hydrophilic membrane and optimized pleated structure provide efficient liquid wetting, high flow rate and low initial pressure difference.
Excellent Microbial Retention
Uniform pore size and fine membrane grades support high filtration efficiency and reliable microbial retention in sensitive liquid applications.
Low Extractables & Broad Compatibility
The membrane contains no added binders, has low precipitates and can filter a variety of compatible aqueous and non-aqueous liquids.
Large Membrane Area
A large pleated membrane area provides strong dirt holding capacity and supports longer operating cycles.
Naturally Hydrophilic
PES media wets readily with water and does not require pre-wetting with alcohol for common aqueous filtration.
Uniform Pore Distribution
Controlled pore structure improves filtration consistency across the cartridge surface.
Product Structure & Material
PES membrane media is supported by non-woven layers and a polypropylene cage. The cartridge is thermally welded without adhesive to reduce contamination risk.

How Micron Rating Affects Flow
Finer membrane grades provide higher particle or microbial retention but create greater pressure drop. Coarser PES grades support higher flow and lower resistance in the same housing.
Higher Retention
Lower Micron = Higher ΔP
Higher Micron = Higher Flow
