◆Selective Gas Permeation Principle by Difference in Solubility and Diffusion Rate

•
Gases of low molecular weight (H₂O, H₂, O₂, etc.) have a higher solubility and diffusion rate than high molecular weight gases (N₂, CH₄, etc.) and quickly penetrate through the inside of the module
•
Low molecular weight gas permeates the membrane, and high molecular weight gas remains and separates

◆Various Applications Available with Excellent Heat Resistance & Hydrolysis-Resistance

Applied Field Contents
Oxygen generator • Aerobic microorganism culture
• Medical and general air conditioning equipment
• Waste treatment by smelting and incineration
Nitrogen generator • Exhaust and inert gas filling of chemical process tanks and containers
