Hydraulic Filter


A 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. Their size is on a scale of micrometers, meaning hydraulic filters must be properly sized to filter out even the smallest of particles.

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. However, considerations for cost and space impact where designers choose to place 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. Ensuring your hydraulic filter suits your equipment's needs the first time around will prolong its life and allow you to work more efficiently.
