How to Size a Filter Element
The downstream equipment being protected determines the
micron rating of the filter element. Industrial tools, such as air
hammers and drills, typically require only a 40-micron element.
Air operated instruments and small, high speed tools typically
require a 5-micron element. Always consult the equipment
manufacturer for filtration requirements.
Generally, the smaller the micron rating of the element,
 the higher the pressure drop across the filter,
 the shorter the element service life.

Therefore, the use of a 5-micron element where a 40-micron is
adequate penalizes the customer in increased pressure losses
and frequent down time for changing or cleaning the filter element

Filters have their flow measured in terms of thepressure drop across them. As the flow increasesthen the pressure drop also increases. These pressure drops are energy losses in the system.
A well designed filter not only removes water and particles efficiently, but also has a low pressure drop at a given flow. The flow figures quoted in Norgren catalogues for general purpose
filters are at a pressure drop of 5 psig (0.3 bar),
from a 100 psig (7 bar) inlet pressure. Beware! not all competitors quote their flows under the same conditions. If a higher inlet pressure is used or a higher pressure drop is quoted
then the apparent flow will be higher. This does not mean it is a better unit , simply that a different point on the curve has been selected. Often the only way to compare units is to test them under the samelaboratory conditions.
