Introduction
In the complex and precise world of industrial machinery, hydraulic systems play a vital role. These systems based on pressure transmission through pressure fluids are used in a wide range of industries such as automotive, aerospace, construction, production and agriculture. The beating heart of any hydraulic system is its oil or hydraulic fluid. But the fluid, though initially pure and free of contamination, is constantly exposed to external particles, dust, metal crumbs caused by components, and even by -products caused by fluid oxidation. The presence of these pollutants, even in very small amounts, can lead to serious and costly damage to the sensitive components of the hydraulic system such as pumps, valves, cylinders and motors. These damage can include rapid abrasion of parts, reduced efficiency, increased temperature, fluid leakage, and ultimately complete system failure.
This is where hydraulic filters enter the field. The hydraulic filter, such as the kidneys, is responsible for clearing the hydraulic fluid and removing pollutants. Choosing and using the appropriate hydraulic filter is one of the key factors in guaranteeing the life expectancy, reliability and efficiency of hydraulic systems. On the port filter website, we understand the importance, we are proud to provide a complete set of the most quality hydraulic filters for your varied industrial needs. This comprehensive guide helps you make the best decision for your system by accurately understanding the types of filters and their selection criteria.
Why is the choice of appropriate hydraulic filter?
Hydraulic Filter Incorrect Select can have unfortunate consequences for your system:
Types of Hydraulic Filters: Introduction to Categories
Hydraulic filters can be categorized by different criteria, but the most common categorization is based on their location and performance in the system:
suction filters:
Place: before the hydraulic pump, in the fluid inlet path to the pump. Function: These filters are usually made with a mesh or metal basket and are responsible for protecting the pump against coarse particles. Their filtration is relatively low (eg 100 to 150 microns). Benefits: direct protection of the pump, prevent large particles from entering the system. Considerations: The pressure drop in these filters should be minimal so that the pump's suction does not hurt. Are usually not equipped with bypass.
Pressure Filters:
Place: after hydraulic pump, in the main pressure line of the system. Function: These filters are the most accurate and critical system filters because they have the task of removing fine particles (up to 1 to 10 microns) that can damage the sensitive components. They are usually manufactured in resistant metal chambers and are often equipped with bypass valve. Benefits: Protection of hydraulic valves, operators (cylinders and motors) and other sensitive components against fine particles. Considerations: should be able to withstand high pressure and pressure fluctuations in the system. The pressure drop is important in them, but the accuracy of the filtration has a higher priority.
Return Filter (Return Filters):
Place: on the fluid return route from the system to the tank. Function: These filters remove particles that may be suspended by abrasion or entered through small leaks. The degree of accuracy of their filtration is usually between average and top (eg 10 to 25 microns). Benefits: Fluid cleaning before returning to the tank, reducing overall system pollution load. Considerations: are usually equipped with bypass valve to prevent the fluid from returning to the tank if filtered cramps.
Line Filter (In-Line Filters):
These filters can be installed anywhere on the hydraulic lines (suction, pressure or return) and will have a function similar to suction, pressure or return filters depending on the installation location.
Cool Filters:
Sometimes the hydraulic fluid also flows in cooling systems and requires filtering. These filters are designed for this purpose.
Water Separators (Water Separators):
In some applications, the presence of water in the hydraulic fluid is a serious problem. These filters separate the water from the fluid.
key criteria in selecting appropriate hydraulic filters
Selection of the appropriate hydraulic filter requires many factors to ensure optimum performance and system life:
filtration accuracy (Filtration Efficious / Beta Ratio):
This is the most important criterion. The accuracy of the filtration is shown with "beta" (1). The beta number indicates that the filter is multiplied by the removal of particles of a specified size. For example, β10 = 200 means that the filter traps 200 particles of 10 microns per 200 input particles (ie, 99.5% removes 10 micron particles). Determination: The amount of accuracy required depends on the sensitivity of the system components and the type of user. Pumping pumps and precision valves require higher accuracy filters (high beta in small sizes).
Influuid Absorption Capacity (Dirt Holding Capacity - DHC):
This criterion shows how much contamination can keep the filter before complete clogging. A higher DHC filter will have a longer life and require less replacement. Importance: Choosing a proper DHC filter reduces the cost and storage time.
Pressure Rating Ability:
Filter must be able to withstand the maximum pressure it experiences in the system. This includes continuous work pressures as well as Surges. Pressure filters are usually designed to withstand very high stress.
Pressure Drop (Pressure Drop):
Each filter generates some strength to the fluid flow that causes pressure drop. The initial pressure drop (when the filter is clean) should be permitted in the range so as not to affect the pump performance. The final pressure drop (when the filter is on the threshold of cramps) should also match the value set in the bypass valve. Importance: High pressure drop is harmful in suction filters, but in pressure filters it can indicate the performance of the filter (albeit until clogging).
fluid compatibility (Fluid Compatibility):
Filter body and element material (paper, fabric, metal) must be compatible with the type of hydraulic fluid used (mineral oil, synthetic, water-glycol, etc.) to prevent the corrosion or destruction of the filter.
Temperature Rating:
Filter must be able to work effectively in the system's operating temperature range.
Connection Type:
Filters are available with a variety of connections (thread, flanges, cartridges). The connection should be selected to match the plumbing and components of your system.
bypass valve (bypass valve):
As mentioned, the pressure and return filters are usually equipped with bypass milk. This valve opens a substitute for fluid in the filter to prevent damage to excessive pressure or discontinue fluid flow. The bypass setting pressure adjustment should be carefully selected.

Hydraulic Filter Selection Checklist:
Follow the steps below to ensure the correct choice: Specify the type of hydraulic system (industrial, moving, marine, etc.). Know the maximum work pressure and system pressure peak. Specify the type of hydraulic fluid used. Determine the operating temperature range of the system. Specify the required filtration accuracy (based on the sensitivity of components). Determine the location of the filter (suction, pressure, return). Do you need milk bypass? In what pressure? Contact the "Port Filter" experts to check the best options.
Hydraulic Filters Maintenance Tips:
Regular Inspection: Check the status of the filter (cramping, leakage) regularly. Many filters have a clogging indicator. Replacement Schedule: Replace the filters as recommended by the manufacturer or on the basis of periodic inspections (such as timing or pressure drop check). Early replacement may be unnecessary and expensive, but late replacement can be catastrophic. Use Original Spare Parts: Always use filter elements or complete filters and similar quality filters. hygiene: When replacing the filter, be careful not to enter the contamination.
