TEST #12 Venting and Gas Filtration Vent Filter Selection Guide

ガスまたはベントフィルターを選択するときの最も重要な考慮事項は、空気流量や、粒子または微生物の捕捉です。フィルターのメンブレン材料は、十分なろ過面積を持ち、そのシステムに必要な空気流量を実現できるだけのスペースがあるものでなければなりません。The filter should also efficiently retain particles and aerosol droplets, and, if sterile air or gas is required, retain bacteria.
