When to Replace Filters？
什麼時候該交換濾心？
The pressure difference is an important index to judge the life of the filter element. Generally, the set working pressure is about 0.5-3 kg. If the pressure rises to exceed the set standard value (design according to different conditions), the filter element needs to be replaced.
Periodic exchange (meaning a fixed time period) and batch exchange (meaning a fixed amount of material usage) are good practices for maintaining filtration quality.
壓力差是判斷濾心壽命的重要指標，一般設定工作壓力約0.5-3公斤不等，如果壓力上升到超過設定標準值(依條件不同設計)就需更換濾心。
定期交換(指固定時間周期) 及批量交換(指固定材料使用量) 是維護過濾品質的良好使用方式。
