Good selection protecting your system & saving your money.
– When oil going through the filter with this parameters
Bigger Surface area :
⇑ Increasing the quantity of removed contamination. 
⇓ Reducing pressure difference (Δ P ).
More of Layers :
⇑ Increasing the quantity of removed contamination.
⇑ Increasing the filter efficiency ( βx )
-The price of the filter element is related to the surface area and number of layers.
How to quick calculate surface area
-Approximate surface area = 2 X numbers of fins X fin depth X element height
Filtration ration, βx ( filtration efficiency )
-This means the ratio between particles counted up stream and
down stream,
Dirt – holding capacity
Gravimetric determination of the mass particles in grams according
to ISO 4572 is the mass which could be absorbed by the filter element
until a point where one of the test limits ( time or pressure ) is reached.
Warning of bad material
Layer #6 Steel wire mesh , you have to be sure of its quality to avoid damaging as in the pictures
Warning of Bad construction
–Center Tube. You have to check it to be sure of steady flow without any losses.
