With reliable separation performance, exceptional chemical resistance, and food-grade safety, this ultrafiltration system ensures clarity, concentration, and purification across a wide range of applications.
Optimized Ultrafiltration Membrane for Food Processing Applications
The LEFILTER's SFP Series ultrafiltration (UF) membranes are specially designed for food and beverage filtration processes such as protein separation, whey concentration, milk processing, juice clarification, and gelatin concentration. By employing
The SFP Series ultrafiltration (UF) membranes are specially designed for food and beverage filtration processes such as protein separation, whey concentration, milk processing, juice clarification, and gelatin concentration. By employing hollow fiber ultrafiltration membrane technology, these modules enable selective separation of macromolecules while allowing essential nutrients and flavor components to pass through, preserving product integrity and taste.
These UF modules operate within the molecular weight cut-off (MWCO) range of 10,000–100,000 Daltons, making them ideal for a wide array of food industry requirements. Whether you are filtering dairy, plant-based proteins, starch derivatives, or functional beverages, the Ultrafiltration Membrane for Food Processing ensures efficient throughput with minimal fouling and long-lasting durability.

DuPont DOW Equivalent Performance and Compatibility
The LEFILTER's SFP Series is fully compatible with well-known brands such as DuPont (formerly DOW FilmTec), offering a reliable replacement solution without compromising quality. These membranes are made using hydrophilic PVDF (polyvinylidene fluoride) or PES (polyethersulfone), depending on model selection, ensuring high mechanical strength, chemical resistance, and biological safety.
Whether replacing existing DuPont DOW ultrafiltration membranes or integrating into a new food-grade system, the SFP Series allows for seamless installation and reliable performance. Their plug-and-play design reduces downtime and ensures process continuity for food processors globally.
