For every application we have the appropriate solution.


In order to minimise different risks we are at your disposal with our expertise and are able to provide you with a filter device which fits your application in question.

Generally, we distinguish between the following applictions, when we are configurating our filter devices for you.

Oil mist

Oil mist takes place during processing with pure oil as a cooling lubricant. Oil mist can be described as a large amount of fine airborne oil drops or liquid particles, resulting from turning, milling, drilling and grinding with oil as well as processing with minimal quantity lubrication.

Emulsion mist with smoke

Emulsion mist takes place when processing with water mixable cooling lubricants. Emulsion mist can be described as a large amount of fine airborne liquid particles,  resulting from turning, milling, drilling and grinding with water mixable cooling lubricants.

Oil/Emulsion mist

With smoke production.In heavy metal working with oil or emulsion ( with more than 5% oil) smoke production can arise due to high process temparatures. Especially smoke is very difficult to filter due to the small size of its particles.

Digital filter device control system l We make filter device processes visible


ISI-TRONIC is the new filter device control system from ISI, which completely redefines air purification. For the first time it is possible to display all relevant working parameters, for example the degree of soiling of the different filter levels, the air volume flow or the differential pressure in the filter device in real time. Additionally, you can set the values for the air volume or the control reserve yourself.

With immediate effect all air filter devices from the COBARON, MEBARON and ELBARON series are available, as standard, with ISI-TRONIC. Invest in the future and consult us!
