The Strainrite Companies Oil Absorption Logs are made from polypropylene melt blown microfiber and felt media. The log is surrounded with a heavy polypropylene mesh cover with a polypropylene center core for rigidity. These logs can either be inserted inside a filter bag or can float on top of oil contaminate drums or vats.
The unique design enhances the media’s ability to “wick” the free oil and grease from contaminated liquid. The only Delta P restrictions you have is based on that of the filter bag itself, as the flow of liquids passes around the oil log.
