  • Measuring Filter Pressure Drop 2018 01 22

    Anyone who has attempted to measure the pressure drop of a filter mounted in a filter grille will admit its a challenge.Some installations have a significant amount of return duct between the filter grille and the air handling equipment while others are mounted on a platform with no duct.With all the variations, how can you accurately measure this pressure drop without going through a lot.

  • The Importance Of Measuring Your Pressure Drop

    As the filter media collects dirt, sediment, and other contaminants, the pores in the media become clogged.The initial result of this is a less efficient system due to the clogged medias restricted flow and increased pressure drop across the media.The differential pressure increases as more and more material are collected.
