尚、図6は図5のA-A断面図である。
図においては、最も高効率な水分供給を図る為、両端が充填接着剤400によりポッティングされた中空糸膜100に対して、端から端へ流入ポート600と流出ポート700とを禅掛け(周方向に180度ずれた軸方向反対側)に加湿空気を流す様にモジュールケース500に配置する。
更に、この種膜モジュールは、モジュールケース500を、図示しない外部ケース部材内に配置し、この外部ケース部材の内壁面とモジュールケース500の外壁面との隙間に、シール部材を介在させて、隙間を液密にシールする構成としていた。
また、外部ケース部材の両端には、それぞれ中空糸膜内を流体が流れるための流入口と流出口が設けられ、更に、その両端近傍の側面には、それぞれ、中空糸膜の外面をクロスして流れるための入口と出口が設けられる形で使用されている。
更に、ケースが2層構造となっているため、組み立て工数も多くかかった。
