Vacuum filters are installed before the pump, whereas pressure filters come after the pump. Pressure filters often have additional pressure gauges. One gauge measures the pressure of water as it enters the filter (influent), and the other measures the pressure of the water as it flows out of the filter (effluent). The difference between the pressure readings on these gauges is called the differential. The trapped particles build up and eventually slow the water’s flow through the filter, reducing pressure on the effluent gauge and making the differential exceed a predetermined limit established by the manufacturer.
