Location of Filter in Hydraulic System

Hydraulic filters are very important to ensure the cleanliness of the hydraulic system. However, people often ignore their position in the machinery. So where in the hydraulic system would the filter be located? Hydraulic filters are placed at various locations throughout a system to catch contaminants created at different points in the process. For ideal filtration, filters would be before and after the pump, in the return lines, off-line and within the reservoir.

What is a hydraulic filter?

Material of hydraulic filters

Hydraulic filter is a component within a hydraulic system that removes particulate matter from the hydraulic fluid . The filter element catches contaminants and prevents them from re-entering the fluid flow and damaging other pieces of equipment further downstream.They come in different types and configurations, each having unique benefits.

The basic components of a hydraulic system


Before going over the details regarding types of hydraulic filters , here is a brief review of the basic components of a hydraulic system:

Reservoir – holds hydraulic fluid that powers the whole system

Filter – prevents contaminants from entering the system

Pump – moves hydraulic fluid throughout the system

Lines – tubes, pipes, and/or hoses that transport fluid to/from the hydraulic cylinder

Control valve – extends/contracts the cylinder

Hydraulic cylinder – creates linear motion in the system

Particles or contaminants may enter into a hydraulic system for a number of reasons, such as a seal failure. However, the most common occurrence is during routine maintenance when a cap or seal is removed.To prevent any substances from entering the system, the right type of hydraulic filter should be used at all times. The filter hydraulic oil will remove any contaminants that may have entered from a previous cycle before returning the fluid to the reservoir to ensure the system always has clean fluid. Depending on the system, the hydraulic filter may be located in the reservoir or just before it somewhere on the return line.

Hydraulic Filter Types

Low-pressure filters

Low-pressure filters are vital components used in hydraulic filtration systems to maintain fluid cleanliness and prevent damage to sensitive components. These filters are designed specifically for lower pressure applications such as return lines, suction lines, or low-pressure circuits. By capturing and retaining contaminants like dirt and debris, low-pressure filters ensure the smooth operation and longevity of hydraulic systems.

Medium-pressure filters

Medium-pressure filters play a crucial role in hydraulic systems, specifically designed for applications that operate under moderate pressure conditions. These filters are commonly used in hydraulic circuits to remove contaminants and maintain the cleanliness of the fluid. By effectively capturing and retaining particles, medium-pressure filters help prevent component wear, system malfunctions, and ensure the reliable operation of the hydraulic system.

High-pressure filters

High pressure filters are vital components in hydraulic systems that are specifically designed to handle demanding applications with elevated pressure levels. These hydraulic high pressure filters are engineered to withstand high operating pressures and effectively remove contaminants from the fluid. By maintaining fluid cleanliness, high pressure hydraulic filters help protect sensitive hydraulic components, ensure optimal system performance, and extend the lifespan of the equipment. 

Inline Filters

Inline hydraulic filters are installed directly in the hydraulic line and come in various configurations such as cartridge filters or hydraulic inline filters housings with replaceable filter elements. They are typically positioned in the pressure or return lines to capture contaminants before they reach critical components.

Suction Filters

Suction filters are placed in the hydraulic reservoir or directly on the suction line to prevent larger particles from entering the hydraulic pump. They ensure the cleanliness of the fluid as it is drawn into the system.

Return Filters

Hydraulic return filters are positioned in the hydraulic return line, typically after the hydraulic components, to capture contaminants before the fluid is returned to the reservoir. They help maintain the cleanliness of the hydraulic fluid, ensuring the smooth operation of the system.

Spin-on Filters

 Spin-on filters are self-contained filters that are easy to replace. They consist of a filter element and a housing that can be quickly spun on or off for maintenance. These filters are commonly used in various hydraulic systems and are available in different micron ratings and configurations.

How to change hydraulic filter?

1.Identify the location of hydraulic oil filters in your equipment or machinery.
2.Ensure the system is depressurized, and place a drain pan beneath the filter to catch any residual fluid.
3.Unscrew the filter housing or remove the filter cover, replace the old filter with a new one, and securely reassemble the housing. Dispose of the old filter properly. Remember to use the correct filter size and type recommended by the manufacturer and refill the system with fresh hydraulic fluid if necessary.(Reference blog 'How to Clean and Change Hydraulic Filter ')

Clogged hydraulic filter symptoms

●Decreased Performance:

A clogged hydraulic filter can restrict the flow of hydraulic fluid, resulting in reduced performance and slower operation of hydraulic systems. You may notice decreased power, slower response times, or diminished overall efficiency.

●Increased Operating Temperature:

When a hydraulic filter is clogged, it hinders the proper circulation of hydraulic fluid, causing increased friction and heat generation. This can lead to higher operating temperatures, which may be indicated by elevated temperature readings or overheating of the hydraulic system.

●Noisy Operation:

As the hydraulic filter becomes clogged, it can create turbulence and cause fluid cavitation, resulting in unusual noises such as whining, buzzing, or knocking sounds. These noises can indicate restricted flow and potential damage to the system components.

●Contaminated Fluid:

A clogged hydraulic filter is unable to effectively remove contaminants from the hydraulic fluid, leading to a buildup of dirt, debris, and particles. If you notice a dark or murky appearance of the hydraulic fluid, it may indicate contamination due to a clogged filter.

●System Malfunctions:

A clogged hydraulic filter can cause various system malfunctions, such as erratic operation, jerky movements, or even complete system failure. These issues occur due to inadequate fluid flow and compromised performance of the hydraulic components.
