The filterability test rig is used for testing the filtration properties of fluid lubricants in the process of developing such lubricants. During the test run the testing medium is heated, a controlled amount of water is added and the medium is pumped through the filter. Characteristic data such as flow rate, differential pressure, temperature and
humidity values are evaluated and recorded by the control system. In addition, the Flender oil foam test system can be used to determine the foaming characteristics of the testing medium in accordance with ISO12152 prior to and after the filterability test. The filterability test rig is built under license of ISP Salzbergen GmbH & Co.KG.
