SJ-C Series (Clarifier)

The SJ-C series is the clarifier variant of MKK/MHI's SJ separator family. Identical base unit as the SJ-F (fuel purifier), but with clarifier disc stack and without gravity disc. Standard as LO separator on Japanese newbuilds with MHI main engines. Installed in parallel to the SJ-F — one for fuel, one for lube oil.
