Cooling lubricants in useĀ
Applications for mechanical and electrostatic air filter devices. Applications for mechanical and electrostatic air filter devices.
When selecting an industrial air cleaner, the use cases oil mist, emulsion mist and oil/emulsion mist are classified.
Oil mist
Oil mist is generated during machining with pure oil as a cooling lubricant. Oil mist is a large quantity of airborne, very fine oil droplets which are produced during turning, milling, drilling or grinding with oil and during dry machining with MQL (minimal quantity lubrication quantity).
Emulsion mist
The use of water-miscible cooling lubricants produces emulsion mist. This is a large quantity of airborne, very fine liquid particles. These particles are often produced during turning, milling, drilling and grinding and can be harmful to health if inhaled.
Oil/emulsion mist
Oil/emulsion mist with smoke development. During heavy-duty machining with oil or emulsion (with more than 5% oil content), oil or emulsion mist with smoke development occurs due to the high process temperatures. Smoke in particular is difficult to filter due to its very fine particles.

The benefits of ISI air filter systems
Air filter devices from ISI Industrieprodukte GmbH can be used economically and cost-effectively.
The applications for air filter devices are individual and depend on factors such as the cooling lubricant to be used or the size of the machine work area to be extracted.
However, the benefits and potential savings that can be achieved by using an air filter are the same. We will be happy to advise you and identify the individual benefits and possibilities together with you.
Clean air and safe working conditions
Our air filtration systems ensure clean process air, protect employees and bring about a lasting improvement in working conditions.
Less maintenance thanks to long-lasting filters
Our air filter systems are designed to ensure the filter media lasts a long time, significantly reducing the need for maintenance and downtime.
Reduced operating and energy costs
Our air filtration systems reduce energy consumption through efficient filtration, providing long-term savings on operating costs.
Reduced cleaning requirements in production
Our air filtration systems keep machinery and production areas clean, reducing cleaning time and costs.
ISI Group – three competencies one common path
ISI Industrieprodukte GmbH | ISI-Vertriebs GmbH | ISI Service GmbH
The ISI Group develops, produces and markets industrial air filters for industrial air pollution control.
The medium-sized, family-run company with headquarters in Buchholz in the Westerwald region of Germany has been one of the leading filter device manufacturers in GermanyĀ for over 50 years and has sold during this time over 70.000 air filter units.
