EVERY MINUTE ONE MILLION PARTICLES THAT ARE LARGER THAN 1 MICRON (0.001 MM) CAN ENTER A HYDRAULIC SYSTEM.
The wear of hydraulic system components is dependent on this contamination, and the existence of metal parts in hydraulic system oil (iron and copper are particularly powerful catalysts) accelerates its degradation. A hydraulic filter helps to remove these particles and clean the oil on a continuous basis. The performance for every hydraulic filter is measured by its contamination removal efficiency, i.e. high dirt-holding capacities.

A hydraulic filtration system includes hydraulic filters to remove dirt and particles on a continuous basis.
A hydraulic filter helps to remove these particles and clean the oil on a continuous basis. The performance for every hydraulic filter is measured by its contamination removal efficiency, i.e. high dirt-holding capacities. Almost every hydraulic system contains more than one hydraulic filter. The hydraulic filters between pump and actuators are referred to as pressure filters and the hydraulic filters between the actuators and tanks are low pressure or return line filters.
