TEST #12 Venting and Gas Filtration Vent Filter Selection Guide

기체 또는 환기 필터를 선택할 때 고려해야 하는 가장 중요한 사항은 공기 유량과 미립자 또는 미생물 잔류량입니다. 필터의 멤브레인 재료는 시스템에 필요한 공기 흐름을 감당할 수 있을 정도로 충분한 표면적이나 공간을 제공해야 합니다. The filter should also efficiently retain particles and aerosol droplets, and, if sterile air or gas is required, retain bacteria.
