What is the function of the differential pressure indicator of the FH series?
-
The indicator allows you to visually determine when the element needs to be replaced.
When the element is clogged and the differential pressure between the inlet and outlet sides increases, the red ring will start to float in the indicator window. When it floats to the top, covering the entire indicator window, replace the element. Once it has floated to the top, the red ring will remain there, so after replacing the element, press the reset button on the top to reset it.
The differential pressure under which the red ring operates depends on the filter specifications.
