Pleated Membrane Filter Cartridge

Pleated Membrane Filter Cartridge
Discover our extensive range of pleated membrane filter cartridges, designed to deliver reliable, efficient filtration while maximizing service life.
Our products are widely used in the food and beverage, pharmaceutical, and chemical industries.

Pleated Membrane Filter Cartridge
From laboratory‑scale filters and filter bags to production‑scale standard filter cartridges, our comprehensive membrane product portfolio employs the same media and structural materials, ensuring seamless scale‑up and eliminating the need for revalidation.
Our membrane filters employ advanced heat-sealing technology to ensure a robust, leak‑tight seal on all components, enhancing equipment integrity and providing resistance to a wide range of solvents, acids, and bases. The chemically resistant polypropylene material supports filter regeneration, while the all‑polypropylene construction minimizes extractables.
All our products are manufactured in a controlled environment in strict compliance with ISO 9001 standards and fully meet the requirements of EU Regulation No. 1935/2004. Furthermore, all materials we use comply with FDA Title 21 and USP Class VI specifications, ensuring full batch traceability for your peace of mind.

Low Bioburden Sterilization-Grade Filter
Our membrane filtration product line provides efficient filtration of high-value liquids in both food and industrial applications.
The PES Plus series comprises three products—SME+, BME+, and SME‑X—featuring hydrophilic PES (polyethersulfone) membranes paired with PET (polyethylene terephthalate) support layers and integrated copolymer end caps, offering excellent wettability and low pressure drop. For applications requiring polypropylene end caps and support layers, we also offer the SME, BME, and SME‑X series.
They are widely used for water filtration, the removal of yeast from beer and wine, cold stabilization of alcoholic beverages, and the final filtration of beverages.

Sterile-grade filtration
SMV and SMV-X sterilizing-grade membrane filters are designed to effectively remove microorganisms from valuable liquids in food and pharmaceutical applications.

They can be used for cold stabilization of alcoholic beverages, sterilization of bottled water and process water, and filtration of eye serums.

Its filtration medium is made of a double-layer asymmetric hydrophilic SMV membrane, with the support layer integrated into a robust housing equipped with a reinforced filter cartridge and end caps, making it suitable for virtually all operating, maintenance, and cleaning conditions.
Their key features include high flow rates and low pressure drop, broad chemical compatibility, no need for pre-wetting, and low adsorption of proteins, pigments, and flavoring agents.

High-Temperature Sterilization Grade Filtration
SMT filters are entirely made of polypropylene and feature heat-sealed joints that ensure the integrity of the unit while providing chemical compatibility with a wide range of solvents, acids, and bases. SMT filters are widely used in the pharmaceutical, cosmetic, and chemical industries for sterilizing corrosive liquids, achieving complete retention of particles and contaminants, and performing pre‑filtration and final filtration of oxidizing fluids.
The SMT-P filter provides safe, reliable, and efficient bioburden control and sterilization for oxidizing, corrosive, and erosive liquids. It effectively retains particles and microorganisms through a single-layer asymmetric hydrophobic PTFE membrane, with its bacterial retention performance thoroughly validated. Key features include a 100% perfluoropolymer construction, proven bacterial retention capability (for the 0.2 µm model), and high flow rates with low pressure drop. Thanks to its chemical compatibility, the SMT-P filter is widely used in water treatment, pharmaceuticals, cosmetics, and the chemical industry.
SMT‑H sterilization‑grade membrane filters deliver highly reliable and safe microbial reduction in critical applications. They are suitable for sterilizing corrosive liquids, ozone‑water disinfection, and high‑temperature water filtration. Their exceptional dirt‑holding capacity and durable materials ensure an extended service life. The filter media consists of a pleated, single‑layer, inherently hydrophilic PTFE membrane, with a PPS support layer integrated into a robust housing featuring reinforced end caps, making it well‑suited to virtually all operating, maintenance, and cleaning conditions. Key features include high flow rates, low pressure drop, and broad chemical compatibility.

Sterile Air and Gas Filtration
SMT-G sterilization-grade PTFE membrane filters provide absolute filtration of gases in the food, pharmaceutical, and industrial sectors.
They are suitable for sterilizing compressed air, nitrogen, and other gases; for sterilizing aeration tanks; for inlet and outlet gas filtration in fermentation vessels; and for absolute final filtration. The filter media consists of a pleated, single‑layer, inherently hydrophobic PTFE membrane, with a support layer integrated into a robust housing featuring reinforced filter cartridges and end caps, making it well‑suited to demanding operating and cleaning conditions.

Hydrophilic nylon membrane
The SMN‑X filter enables safe, reliable, and effective bioburden control and sterilization of high‑value fluids used in the food and beverage, pharmaceutical, and chemical industries. Featuring a dual‑layer hydrophilic nylon 6,6 membrane, it efficiently retains particles and microorganisms, with bacterial retention performance thoroughly validated. Key features include high flux, low pressure drop, inherent hydrophilicity, a dual‑layer membrane structure, and compatibility with integrity testing.
The SMN‑XZ filter effectively retains particles and microorganisms by employing a double‑layer, modified Zeta cationic hydrophilic nylon 6.6 membrane, thereby enhancing its ability to capture sub‑micron particles—such as endotoxins and other contaminants commonly found in pharmaceutical and biological solutions. The filtration medium, supported by a backing layer, is integrated into a robust housing or enclosure, making it suitable for virtually all operational, maintenance, and cleaning applications. Key features include positively charged, dual‑layer media for endotoxin removal, high flow rates, and low leaching of filtrate.
