Metal working fluids are used to cool and lubricate the machining activity, prolong the life of the tool, carry away debris and protect the surfaces of the work pieces. The metal working fluid is a complex mixture, which may contain oil, additives such as biocides and rust inhibitors etc. as well as contaminants like metal fines, tramp oil and bacteria.

 

Oil mist/Aerosol
During machining, mist is produced by the interaction of the fluid with the moving parts. When liquid hits fast moving parts, it is thrown back and dispersed as fine droplets. The generation of mists are mainly depending on:
• Higher speed of tool = higher generation of mist
• The volume, rate and point of delivery of metal working fluid to the cutting edge.

 

Coolant smoke
If metal working fluids become excessively hot they may start to ”burn” and degrade. During machining of metal parts reaching a high temperature, such as grinding procedures, smoke may be visible.

 

Vapour / Gas phase
The gaseous state of any liquid is formed as molecules leave (evaporate from) the surface of the liquid. The evaporation increases with low boiling point of the liquid and increased temperature of the fluid. In water based emulsion the evaporation will increase the humidity in the plant.

Machining processes produce many hazardous contaminants that origins from the metal working fluids. Machinists are usually well aware of the safety hazards associated with operating machines. Less known are the health hazards associated with the use of metal working fluids.

 

During milling, turning, grinding and boring (and other metal-cutting machining activities) metal working fluids form a mist of small droplets. The oil mist is suspended in the air and can be inhaled and ingested. When these fluids form into a mist during the machining process the larger droplets can pass into the nose and windpipe and can be swallowed. The smaller droplets can deposit into the lungs. This can off course be unhealthy and very irritating to the eye, nose and throat.

 
Our range of oil mist filters spans from direct mounted filters to central filter systems designed for all metalworking machines in a workshop. The modularity and expandability of the filter ensures easy reconfiguration to handle changes in machine tool processes or type of coolant.

 

MistWizard

The MistWizard is a direct mounted filter solution for single or multiple machine tool applications.
 

Mist Eliminator

A modular mechanical oil mist filter system. Its flexibility allows expanding and adapting to changes in machine tool processes.

EFO

The combination of mechanical and electrostatic filtration puts the EFO in the front line of oil mist filtration technology. Suitable for heavy-duty coolant mist and smoke applications.
