Rule of Thumb
#
4: Pressure drop is also caused by the dirt holding capacity of

then clean or replace it when the pressure drop increases b

Rule of Thumb #5: The inlet connection greatly influences the overall pressure
drop of the filter system. To minimize the restriction contributed by an inlet filter, a
