Mechanical Filtration and the Beta Ratio (β): A Technical Deep Dive 1. Why Beta Ratio Matters in Real Machines In turbomachinery lubrication and hydraulic systems, mechanical filtration is the primary barrier against solid contaminants. However, stating that a filter is “10 micron” or “fine” is meaningless without quantifying how efficient it is at removing particles at that size. … Continue reading Mechanical Filtration and the Beta Ratio (β): A Technical Deep Dive
