Differential Pressure Gauge

Under normal conditions, the filter cartridges are replaced by a maintenance schedule. However, with varying conditions of fuel supply, the cartridges may need to be replaced much sooner. The differential pressure gauge gives a visual reading of the condition of the cartridges. These should be checked every time a new batch of fuel is supplied or at very regular intervals.  The typical pressure for replacement is as follows:

  • Filter Water Separator vessel – at 15 PSI or 100 kPa
  • Microfilter vessel – at 25 PSI or 170 kPa
  • Monitor vessel – at 25 PSI or 170 kPa
