Test stand to determine the capability of scrapers to block dust / dirt, that has been applied externally under defined conditions, from infiltrating into a hydraulic system. The foreign particles that have intruded into the system are collected in the plexiglass receptacles which may be seen in the center of the illustration. The oil contained in these receptacles is analyzed / examined for these impurities.
