NAGASEP is a hollow fiber membrane module manufactured using Nagayanagi’s proprietary silicone membrane technology. Our non-porous silicone hollow fibers are produced through a fully automated manufacturing process, ensuring consistent quality and high dimensional accuracy.
NAGASEP offers outstanding heat resistance (operating up to 200 °C) combined with excellent solvent resistance. Thanks to these superior properties, our products are trusted and chosen by many customers.
Uniform membrane structure with minimal UV degradation ensures durable use, backed by a solid quality assurance and stable supply system.
NAGASEP hollow fiber membranes support compact designs and diverse shapes.We flexibly provide customized solutions tailored to each application, ensuring optimal results and maximum customer satisfaction.
Silicone rubber hollow fiber membrane module “NAGASEP” is aimed for advanced operations of gas, vapor and solutions. Hydrogen Water, ink degassing and blood test degassing are some examples.
NAGASEP hollow fiber membrane modules utilize the selective gas permeability of silicone and can be used for a wide range of applications, including gas separation, liquid degassing, and gas injection into liquids.
NAGASEP works by creating a difference in gas concentration or pressure across the non-porous silicone membrane. Gas molecules selectively permeate through the membrane from one side to the other. Depending on the application, this principle can be used to remove dissolved gases, introduce gases into liquids, or separate selected gases.
NAGASEP hopes to contribute widely in the fields of environmental protection, medical care, and food hygiene around the world.
