What are fine oil filtration technologies and their advantages?

Fine oil filtration technologies include:

Depth Filters: Capture contaminants throughout the filter media.
Membrane Filters: Use semi-permeable membranes for sub-micron filtration.
Electrostatic Filters: Remove particles using electric charges.
Magnetic Filters: Extract ferrous particles.
Advantages are:

Improved Cleanliness Levels: Achieve higher purity standards.
Extended Equipment Life: Reduce wear on components.
Enhanced Oil Life: Maintain oil properties longer.
Increased Efficiency: Improve machinery performance due to cleaner oil.
