Dynamic Filter Efficiency (DFE) Testing: Testing methods assure that DFE rated elements perform true to rating even udner demanding variable flow and vibration conditions. Today's Industrial and mobile hydraulic circuits require elements that deliver specified cleanliness under ALL circumstances. Wire mesh supports the media to ensure against cyclical flow fatigue, temperature, and chemical resistance failures possible in filter elements with synthetic support mesh.
Current Industry standards are surpassed byinducing dynamic duty cycles and measuring real-time performance before, during, and after the cycles. DFE testing quantifies both contamination capture and retention efficiency in real time so that we may predict the worst case fluid cleanliness along with average fluid cleanliness.
