The main factors affecting the dehydration efficiency of a coalescer filter element include: flow rate (excessively fast flow shortens coalescing time), temperature (low temperature makes droplets less likely to coalesce), initial water content (excessively high emulsified water overloads the element), oil viscosity (high viscosity hinders droplet movement), and the degree of filter element aging. To maintain optimal efficiency, ensure the filter element operates within its rated flow range and preheat the oil appropriately during cold seasons.
