What types of cutting oil filtration systems are available and how do they work?

Bag and Cartridge Filters: Use replaceable filter media to trap particles; fluid passes through the media, leaving contaminants behind.
Magnetic Separators: Remove ferrous particles by attracting them to magnetic surfaces as the fluid flows through.
Centrifugal Separators: Spin the fluid at high speeds, forcing heavier contaminants outward for collection.
Vacuum Filters: Employ vacuum pressure to draw fluid through a filter medium, capturing contaminants.
Paper Band Filters: Utilize a continuous roll of filter paper to trap particles; as the paper clogs, it advances to expose fresh media.
Hydrocyclones: Use vortex separation to remove particles based on size and density differences.
These systems are selected based on the specific needs of the machining operation and the types of contaminants present.
