Cleanliness of hydraulic system is a subject of great importance for all leading producers of hydraulic and pneumatic equipment. The intense pressure inside a hydraulic system can turn small particulates into big problems. Many hydraulic systems run pressure of 3,000 to 6,000 pounds per square inch. At this pressure, a small particle coursing through the system will abrade, or 'sand,' the surface inside the system, breaking down into more particulates and creating more problems.
