How does oil mist and emulsion mist arise?

In many machining operations, water-miscible (emulsion) or non-water-miscible (oil) liquids are used for both cooling and lubrication.

Rotating spindles, rotating tools and the use of internal cooling systems, often equipped with high pressure, create a very fine oil mist or emulsion mist in the machining section of the machine.

In terms of particle size, oil mist and emulsion mist can be subdivided into a range of 0,5 - 10 microns. The fine mist (<1,5µ) in particular can have harmful effects with prolonged exposure.

Health hazards oil mist and emulsion mist

To minimize health risks, national and international regulations apply to emissions and exposure to oil mist and emulsion mist.

The Netherlands currently has a maximum concentration of 3 mg / m3 with regard to oil mist. The tendency is that, as with welding fumes, this standard will be further tightened in the coming years.

To efficiently remove the harmful oil mist, oil vapor and oil smoke from your machine tools Dormatec Oil mist fillers therefore a must. By using H13 Hepa Filters as the final filtering step, the recirculated air is purified to 99,97% at particle size (oil mist) of 0,3µ (micron).

A measurement on location to the current concentration or after commissioning of a Dormatec oil mist filter is possible.
