Dehumidification in the pneumatic system is an important factor for preventing efficiency decrease and malfunction due to humid air. Various dehumidifier has been developed until now and especially dehumidifier using polymer membrane has been studied for low cost and easy manufacture. In this study, experiment and flow analysis of hollow fiber membrane module were performed for confirming the efficiency of dehumidification which is also related to the pneumatic system performance improvement. Water removal ability and adsorption performance of hollow fiber membrane module were confirmed by results of flow analysis and experiment, and the reliability of the flow analysis could be obtained through the comparison with experiment results. From this study, dehumidification phenomena in the hollow fiber membrane module was found out, and the basic design concept for the next generation dehumidification system was also discussed.
