Low pressure filters are the most commonly used type of filter in hydraulic circuits, used as return line filters in applications with typcial working pressures up to 150 psi and static pressure up to 300 psi. Donaldson offers flow/pressure combinations to fit most applications. Continuous filtrations of bulk fluids through dedicated off-line circuits or kidney loops helps keep fuel, oil and lubricants clean.
