Hydraulic filters are used in hydraulic systems to keep contaminants from the fluid. To do so, the filtration system works by continuously removing the contaminants, ensuring the fluid remains clean for a well-running hydraulic tank filter and system.
To purify and filter hydraulic fluid, different types of filters in hydraulic system units are used, ensuring each system is running well and clean. Some of the most common types of filters include:
• Suction filters: Placed before the pump, suction filters work to prevent large dirt particles from entering the system and damaging the pump;
• Pressure filters: Placed after the pump, pressure filters ensure the fluid is clean before entering the circuit from the pump;
• Return line filters: This is a low-pressure filter that purifies fluid before it returns to the reservoir, filtering out dirt that has accumulated from the pump and actuators;
• Off-line filters: A small independent filtration sub-system that includes a pump, filter, motor, and hardware connections. This filter operates when the machine isn’t active, ensuring the fluid keeps a constant contamination level;
• Air filters: Also referred to as air breathers, this filter focuses on the air entering the system. An air filter is essential to avoiding contamination of the fluid.
