Lubricating Oil Filters

Alfa Laval lubricating oil filters provide full-flow filtration for trunk piston and crosshead engines, with continuous automatic backflushing and more than 12,000 operating hours between cleaning and inspection.

Continuous backflushing

Full-flow filtration prevents contaminants from entering sensitive engine parts, reducing engine wear and boosting reliability.
Types 160, 240, 280 and 350 cover all lubricating oil flows.
Compact, space-saving design enables easy installation and retrofitting as upgrades to existing installations.
Continuous automatic backflushing prevents solids adhering to filter surfaces, eliminating manual cleaning of filter elements.
Low, constant pressure drop across filter elements reduces the risk of cracking. During backflushing there is no pressure drop.
Near-constant pressure in the engine’s lubricating oil system makes malfunctions easier to detect by registering pressure changes.

Specification	Value
Time between cleaning and inspection	more than 12,000 operating hours
Eliminator type engine capacity	up to 5,000 kW
Filtering columns fed with unfiltered oil	11 of the 12 filtering columns
Backflushing frequency for all columns	every one to three minutes

X type: for crosshead engines.
T type: for trunk piston engines.
Eliminator type: for trunk piston engines. Supplements the full-flow automatic filter with a special disc-stack centrifuge that removes particles from backflushed oil, allowing oil to return to the engine sump.
An Eliminator combination provides better protection and extends oil lifetime.
Certain X and T models offer a special diversion chamber that collects particles backflushed from the full-flow chamber, providing automatic, maintenance-free sludge treatment.
Supplied ancillary equipment includes a pressure drop indicator, inspection covers and counter flanges.
Optional additional features include magnetic plates installed on the inlet housing.

A distributor feeds unfiltered oil to 11 columns. Solids collect on the filter surfaces and filtered oil flows to the engine. A small amount of filtered oil backflushes previously collected solids from the twelfth column.
Backflushed oil passes through the distributor and backflushed oil outlet to the lubricating oil sump.
A hydraulic motor on top of the filter housing rotates the distributor at regular intervals. Each full rotation backflushes every column.
Backflushing is driven by the pressure difference between the clean oil outlet (P2) and backflushed oil outlet (P3).
The pressure drop indicator, connected between the filter inlet and outlet, provides a reading and signals an alarm if pressure drop reaches the alarm level, indicating a problem in the lubricating oil system.
