Polyester Nonwoven for Coolant Oil Filtration

Coolant oil filtration is a crucial step during metalworking to guarantee an efficient removal of coolant/rolling oil contamination such as chips and wear. This allows for an ecological and economical re-use of the lubricants while still meeting the high-quality requirements for the final products. Large scale industrial systems like rolling mills are found for instance in the automotive industry and utilize belt or plate filter systems.
