Simplex Filter for Marine Fuels
Filtration for Engine Fuel Valve Trains (FVT)

John Crane’s Simplex filters installed on the Fuel Valve Train (FVT) of dual fuel marine vessels are designed to capture particles from the fuel before it enters the engine and generator. By ensuring the fuel is clean, the filter prevents damage to the fuel injectors and other critical engine and generator components, thereby promoting smooth and reliable operation. Compliance with marine classification societies ABS, BV, DNV, LR, Class NK, CCS.
John Crane's Indufil modular building principle — using machined parts from forgings — offers high flexibility and a compact design that provides plug-and-play solutions for retrofits and upgrades.
