Plant Engineering | Industrial oil filtration

Filters with smaller pores generally operate under a larger pressure differential, since it's harder for the oil to squeeze through. Eventually, the excess pressure on the upstream side can break down the fibers, letting larger particles pass through. One way around this is to increase the filter's porosity (the number of pores for a given ...
