The applicability of the aromatic polyimide membrane to air-drying system was studied. The premeability of steam is estimated to be 1000 times as large as that of nitrogen based on the experiment with the single hollow fiber. The air with -20°C dew-point can be easily produced by the process using this membrane module having several hundreds hollow fibers. But the obserbed permeability ratio was 300-500.
