When the oil-gas mixture is discharged, it must pass through the high-precision glass fiber filter paper of the exhaust filter. Since oil mist particles exist in liquid form, they cannot directly penetrate the filter paper and instead adhere to its surface. Over time, accumulated oil mist particles coalesce into oil droplets that return to the vacuum pump. Meanwhile, clean gas passes through the glass fiber paper under controlled pressure and is smoothly discharged. This process achieves effective oil-gas separation through the vacuum pump filter.
