Fuel Oil Filter · Fuel Oil Treatment
MAHLE Pi 230 DN100 is a fuel-oil filter. It is normally installed in the engine-room fuel treatment or supply system upstream of engines, pumps or other contamination-sensitive equipment. Its purpose is to remove solid contamination from fuel and protect downstream injection and pumping equipment. Depending on the model it may use simplex, duplex, automatic backflushing or another filtration arrangement, which must be confirmed from the installed documentation. The exact model designation and listed connection or capacity information distinguish filter size and arrangement from neighboring units; refer to the manufacturer documentation for the exact filtration grade and flow data.

What our service work and the manufacturer documentation say about keeping this model running.
Monitor differential pressure and downstream fuel pressure and investigate rapid fouling rather than repeatedly bypassing the filter. Inspect elements, baskets, backflush mechanisms, covers, drains and seals for contamination and damage. Maintain fuel temperature and viscosity conditions appropriate to the vessel's fuel system. Clean or replace elements using the approved procedure and prevent dirt entering the clean side during maintenance. Check automatic changeover or backflush functions where fitted. Refer to manufacturer documentation for exact element grade, differential-pressure limits and servicing criteria.
Keep model-correct filter elements or candles, cover gaskets, O-rings, backflush valve or actuator service parts and differential-pressure instrumentation spares as recommended. Carry sufficient consumables for expected fuel-quality variability and voyage duration. Verify exact filtration grade and materials before installation.
