ABSTRACT:
A fluid filter, which is adapted for separating a less dense fluid floating on a high dense fluid, includes at least a fluid filtering arrangement including a floating wing adapted for floating on the less dense fluid and at least a fluid outlet formed on the floating wing, and a container body, which is extended from the floating wing, having a fluid collecting cavity communicating with the fluid outlet, wherein the fluid outlet is formed at a position above the fluid collecting cavity. Therefore, when a downward force is applied on the floating wing until the fluid outlet is slightly positioned below the surface level of the less dense fluid, the less dense fluid is allowed to flow into the fluid collecting cavity through the fluid outlet by gravity.
