Alfa Laval 290 Filter Automatic oil filtration Diesel engines are evolving in order to comply with stringent IMO emissions standards and to improve energy efficiency. As a result, modern engines require filtration adapted to new oil cleanliness standards, without impacting on pressure drop or space consumption. To lift this challenge, available filtering area needs to be increased in an optimized volume. Compact and reliable, the Alfa Laval 290 filter is a self-cleaning disc-type automatic filter designed to protect sensitive engine parts. It provides full-flow filtration, particularly in lubricating oil and hydraulic control oil used for diesel engine installations onboard ships and in power plants. Application The Alfa Laval 290 filter is equipped with innovative Alfa Laval Atrium technology, which enables continuous automatic back ushing filters with virtually no pressure drop, fl even in the case of fine filtration. This innovative technology makes it possible to employ a large filtering area using less space than conventional automatic backflushing filters. It also improves backflushing efficiency due to enhanced distribution method that more effectively disperses the unfiltered oil to be cleaned. Benefits • Maximum engine protection, minimal engine wear The Alfa Laval 290 filter provides fine filtration of particles in oil down to 6 micron in size – with virtually no pressure drop. Its small footprint and large filtration surface area ensure proper engine lubrication and minimal engine wear, thereby safeguarding engine operation. • Compact and versatile The Alfa Laval 290 filter offers up to 30% more filter surface area compared to conventional filters with the same footprint. Its footprint can be made even more compact when the filter is integrated directly into the engine. • Easy to install, operate and maintain No additional electrical power, air connection or dedicated tank is required. The Alfa Laval 290 filter is designed for start-and-forget operation. Large filtering area reduces stress on the filter mesh, thereby prolonging the intervals Alfa Laval 290 filter: More compact footprint, yet higher capacity with up to 30% more filter area than traditional automatic filters. between inspection. In addition, maintenance is quick and easy because there are few parts to disassemble. • Reduced total cost of ownership The Alfa Laval 290 filter is perfectly suited for improving total cost of ownership. Long-lasting wear parts reduce spares consumption and maintenance costs are reduced to minimum. In addition, lubrication oil lifespan can be increased by up to four times if installed with the optional Alfa Laval Eliminator configuration. Diversion-type filters also are an alternative to traditional cartridge-consuming backflush treatme

Design The Alfa Laval 290 filter is engineered for fine particle filtration of lubricating and hydraulic oil – with virtually no impact on pressure drop. It uses innovative Alfa Laval Atrium technology, which offers the best ratio between the filtering surface and the total footprint/volume of the filter available on the market. The filters can be configured as a stand-alone filter, as an engine-mounted filter, or with by-pass valve and redundancy filter to meet virtually any filtration requirements. The Alfa Laval 290 filter can either be mounted to the engine or, when a more compact footprint...
