The hydraulic oil circuit return filter element FX-630*40H has advantages in both performance and price, and can be used for filtering lubricating oil in various industrial fields. When used in the lubricating oil system of power plants, the filter element FX-630*40H can be used as a return oil filter element. As a commonly used filter element, it requires frequent replacement.

It is usually possible to determine whether the oil return filter FX-630*40H needs to be replaced from two aspects: system pressure and filter element differential pressure indicator.

• Differential pressure indicator: The return oil filter device is equipped with a differential pressure indicator, usually a visible pointer or mark. When the filter element FX-630*40H starts to block, the pressure difference indicator will display a certain pressure difference. If it exceeds the specified range, it indicates that the filter element needs to be replaced.
• Change in working pressure of the hydraulic system: If the return oil filter element FX-630*40H is blocked, the working pressure of the hydraulic system may fluctuate or decrease abnormally. If the system pressure is significantly below the normal range, it may be because the filter element is clogged and needs to be replaced.
