Vacuum Filtration
Notes:
First-pass efficiency relates to the basic efficiency of the medium before a filter-cake has been formed.
Dirt-holding capacity relates to how much (fine) dirt the media will remove before blinding-off and stimulating an index.
Vacuum Filter
These factors are important in deciding which material suits a given application. It will be noted that both Infiltra NF95 and Infiltra NF140 have similar micron "ratings" but they have different First-pass efficiency and Dirt-holding capacities. NF95 would lend itself better to a system controlled by timer (perhaps with large quantities of larger size dirt mixed with the grinding debris) whilst NF140 would be the product of choice where indexes are based on vacuum or pressure and high volumes of fine dirt are present.
