Sundstrand Sauer Danfoss Series 40 Charge Pressure Filtration
All series 40 units have charge pressure filtration available. The filter is mounted and is near the circuit after the charge pump (per the diagram). The ratings for the filters are 34.5 bar (500 PSI) pressure A 100- 125 screen in the reservoir or in the charge inlet line.
To prevent damage or contamination from coming in the filter media, a filter bypass valve is needed for the task.
If there should be a high pressure drop that could have caused a blocked filter or from a cold start up, then the fluid will go around the filter. It is never suggested to have an open bypass working for an extended period of time.
You will need a electrical dirt locator and regular routine maintenance is needed on your filter.
