The Grasso Oil  Suction Filter Assembly is a complete filtration unit designed to remove contaminants from the oil before it enters the compressor. This assembly ensures that only clean oil is drawn into the system, protecting critical components such as pistons and bearings from dirt, debris, and other impurities. By maintaining oil purity, the suction filter assembly helps improve system efficiency, reduce wear, and extend the lifespan of the compressor and refrigeration system.
