The primary source of contamination within an engine exists in components and tubes, and occurs during normal operation. Hydraulic filters are necessary for filtering out contamination and debris from hydraulic oil. Such debris includes metal flakes, glass, ash, lint, various fibers, rubber, or sand. By removing harmful dirt and particles, the oil will last longer and extend the life of the engine. Remember: over time, contamination can impact component reliability and the performance of various components. Hydraulic filters remove the contamination and maintain the cleanliness of the oil.
