Oil Mist Filters for Continuous Operation

Nederman has introduced a new range of oil mist filtration products, called Nederman Filtac, based on its FibreDrain technology, designed for continuous operation.

Oil mist and smoke, generated by nearly every metal machining operation, can harm employee health, production equipment and business revenue.

Nederman says the difference between mist and smoke that presents a significant challenge in metal machining operations is that oil mist is comprised of liquid droplets generally up to 20 microns in size. With higher machine speeds and pressure, the mist drops get so small that a liquid smoke, containing droplets less than 1 micron, can be created. Capturing these extremely small droplets requires specially treated and highly efficient filters.

The composition of the FibreDrain filters makes it possible to capture even the smallest submicron droplets and drain them back to the process with maintained filtration efficiency, the company says. The fluid drainage capacity ensures maximum coolant retrieval and reduces coolant consumption.

Additionally, the FibreDrain design secures long filter life and thus low operating cost, the company says. A wide range of filter compositions are available to suit most applications.
