OSF Marine Separator

GEA Westfalia Marine Separator


Machine Application

The GEA Westfalia OSF marine separator is GEA’s newest self-cleaning separator covering all capacities up to 80 m3/h for oil and water treatment. The centrifugal separators from GEA specialize in the purification of fuel and lube oil as well as bilge water treatment and sludge removal in marine applications. With their high g-force, the separators reliably guarantee high performance and economic operation of ship engines, and boost their service life even under extreme conditions.

Separator Design

Incorporating an integrated direct drive, the new GEA OSF marine separator is a revolutionary solution that offers more performance per square meter of footprint, an extremely simple service concept and smart connectivity.

Unlike conventional separators that rely on inefficient conventional motors, clutches, and belts, new GEA OSF marine separator features an integrated direct drive. This provides ship owners with numerous advantages.

Integrated direct drive at the heart of your system.
