Airrane

Airrane makes gas-separation membranes, thin physical barriers built from hollow fiber strands that filter mixed gases and extract specific components such as nitrogen, methane, and carbon dioxide at high purity.

Its products are used wherever industrial or commercial processes require clean, separated gases from a mixture. The company develops and manufactures these membranes itself, with hollow-fiber-based gas separation forming the core of its product line. Airrane is listed on KOSDAQ, South Korea's tech and small-cap exchange.
