Hydraulic Filter Structure

Most hydraulic filters are cylindrical devices with openings for fluid input and output on opposite sides of the filter. The fluid is usually directed through channels in the filter housing and through the filter media. The media then collects contaminants, and the cleaned fluid passes through the central channel between the filter media to the output end. Contaminants are still trapped in the filter medium; when the filter is full, the switch usually triggers an LED or other visual indicator to notify that the filter needs to be replaced.
