Importance of Filtration in Hydraulic Systems and Correct Filter Selection

20 January 2025

The efficiency and longevity of hydraulic systems are directly tied to the cleanliness of the oil used. Over time, contaminants such as dirt, debris, and metal particles can enter the system, causing damage to hydraulic components, performance loss, and even severe breakdowns. The most effective way to prevent these issues is by using the right filters and filter elements. At Hidronest, we ensure your systems operate safely with our high-quality filtration products.

Why is Filtration Important?

Filtration is a critical process in hydraulic systems to clean oil and remove foreign particles. Through filtration:

  • Reduced Risk of Failures: Dirt and debris can damage system components, leading to frequent failures.
  • Improved Performance: Clean oil maintains fluid pressure, allowing the system to operate efficiently.
  • Lower Maintenance Costs: Fewer breakdowns mean reduced maintenance expenses.
  • Extended Component Lifespan: Critical parts like valves, pumps, and cylinders can operate longer without issues.

Types of Filters Used in Hydraulic Systems

  1. Suction Filter
    Positioned before the pump, these filters clean the oil before it enters the system, offering crucial protection for the pump.

  2. Pressure Filter
    Protects system components operating under high pressure, such as directional control valves and hydraulic cylinders, by preventing damage to sensitive parts.

  3. Return Filter
    Cleans used oil before it returns to the reservoir, maintaining the overall cleanliness of the system.

  4. Air Filter
    Installed on the reservoir cap to block dust and particles from entering the system through the air.

How to Choose the Right Filter

  • Oil Viscosity: The filter must be compatible with the viscosity of the oil used.
  • Filtration Rating: Select the appropriate filter based on the filtration precision required by the system.
  • Operating Environment: In dusty or harsh environments, more durable filters should be chosen.
  • System Capacity: Filters should match the system’s flow rate and pressure specifications.
