Nikuni VDF vortex dynamic filters will remove up to 99% of non-ferrous particles down to 25 microns, and 90% of similar particles down to 5 microns in one pass from machine tool coolant. The Nikuni VDF does not contain any moving parts or an element.
Technology developed and applied...
The Nikuni VDF vortex dynamic filters are hydrocyclones specifically designed to enhance the performance of machine tool coolants. This is achieved by removing a large percentage of any metallic particles present in the flow of coolant to the tool head.
Nikuni VDF vortex dynamic filters are available in stainless steel and nylon. Flow rates available range from 20 lpm to 300 lpm
Typical VDF single pass removal performance on aluminium is:
99% of all metallic particles down to 25µm
98% of all metallic particles down to 15µm
95% of all metallic particles down to 10µm
90% of all metallic particles down to 5µm
65% of all metallic particles down to 3µm
Benefits of fitting a VDF hydrocyclone are:
Cleaner coolant and a longer life-cycle
Reduced tool wear
Superior surface finish
Shorter cycle times
No filter elements to block
No filter elements to change
More machine tool up-time and less downtime

Coolant contamination (metallic particles) can be returned to a separate contaminated fluid tank or consolidated in purpose designed sludge pod and dumped at regular intervals. Fully automated air operated sludge pod dump valves are available.
The Nikuni VDF is ideal for building into machine tools and many other items as part of original equipment using water or oil, ensuring that systems can be cleaned by this media-free technology.
See A&M/Nikuni C-CAT application pages for further details and an example of a simple standalone arrangement of the Nikuni VDF hydrocyclones.
