About Hydraulic Filters

Hydraulic Filter is a component within a hydraulic system that removes damaging particulates by forcing hydraulic fluid through a porous filter element.

The filter element catches contaminants and prevents them from re-entering the fluid flow and damaging other pieces of equipment further downstream.

Contaminants range from dirt to water and reactive chemicals.

Functions of Hydraulic Filters

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. There are a few primary locations, which determine the types of hydraulic filters used:

Suction Line Filters:
Low pressure filters, are placed at the pump inlet to ensure no contaminants enter the pump.

In Line Filters:
Medium or high pressure filters, are placed after the pump to keep expensive downstream components safe. Pressure filters have a high-pressure capability to remove internal contamination created within the system.

Return Line Filters:
Are usually low pressure filters. They collect contaminants from the fluid as it returns to the reservoir and can be positioned along the return line or within the tank.

Off Line Filters:
Also called kidney loops, these filters continue working even while the central hydraulic system is not working. An off-line filter draws the fluid from the reservoir and returns it after filtration.

Benefits of Hydraulic Filters

Hydraulic filters extend the life of your hydraulic system and its components considerably. Filters maintain an impurity-free fluid by limiting the intake of contaminants and swiftly removing new ones.

Hydraulic filters also protect components from failure caused by the build-up of particles between close-fitting parts or lubricated mechanisms. Protection from wear and tear reduces the chance of malfunction and keeps systems safer.

An efficient, well-placed filter also saves you money and downtime due to costly replacements or repairs.
