LO4D 27/27 CJC Filter Insert

The CJC® LO4D 27/27 Filter Insert is engineered for offline filtration of engine lubricating oil in medium-speed 4-stroke diesel engines running on gas and light fuels. It is optimised for use with SAE 30 and SAE 40 crankcase oils, where maintaining low contamination levels is critical for engine reliability and long oil service intervals.

The LO4D insert replaces conventional centrifugal separators by delivering superior filtration performance, lower operating costs, and a more compact system design.

Fuel Compatibility

The LO4D 27/27 insert is suitable for engines operating on:

• Marine Gas Oil (MGO)

• Marine Diesel Oil (MDO)

• LNG

• Biofuels

• Hydrogen

• E-fuels

Contaminant Removal Performance

The LO4D filter insert provides a well-balanced combination of high filtration efficiency and strong dirt-holding capacity, allowing effective control of oil contamination levels. It removes:

• Combustion contaminants

• Wear particles

• Oil degradation products

• Asphaltenes

• Water

This ensures the oil remains within engine manufacturer cleanliness limits and helps reduce wear on critical engine components.

System Performance and Benefits

• Frequency-controlled flow rates of up to 250 l/h per filter insert

• Compact design comparable in size to a centrifugal separator

• Very fine filtration for improved oil cleanliness

• Extended filter insert service life

• Increased crankcase oil service intervals

• Lower oil consumption and operating costs

Extensive field experience has demonstrated that the CJC® LO4D 27/27 consistently keeps insoluble contamination levels below engine maker recommendations, delivering long-term reliability and reduced maintenance requirements.
