Rule of Thumb
#
4: Pressure drop is also caused by the dirt holding capacity of
the element. As the element fills up with dirt, the pressure drop increases. It is
important to document the pressure drop across a given filter when it is new and
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
velocity of 6,000 ft
