Pressure on filters

Air conditioning systems are equipped with filters which prevent dirt from the outside air entering the indoor air. These must be regularly subjected to differential pressure measurements to check whether the filter is still fully functional. To do so, the pressure is measured in front of and behind the filter. The result of this measurement is the differential pressure. If it is too high, the filter is contaminated and needs changing.
