Oil mist separator for industry

Oil mist separators are used in industry to extract fine emulsion mists generated by the use of cooling lubricants in machine tools and machining centers. The oily pollutants must be effectively separated to comply with the legal occupational health and safety regulations. The emulsion mist separators bind mist, vapors, aerosols or fume via several filter stages and neutralize unpleasant odors from the hall air. This protects employees, machinery and the purity of your end product.

The separated cooling lubricants collect in a container and can be fed back into the machine tool. As a manufacturer of oil mist separators, we are constantly developing our extraction systems and also manufacture individual extraction solutions for special processes.

Oil mist separator for aerosols, emulsions and vapors

The use of coolants / lubricants in production processes such as milling, grinding or machining, releases fine oil mists, emulsion mists, aerosols and fumes. These contaminants settle on machinery parks, floors or walls. The respirable pollutants endanger employees, contaminate production and increase the risk of fire and accidents.

Oil mist separators from ABSAUGWERK are configured and manufactured specifically for the respective process and the requirements of our customers. Depending on the nature of the extracted oil mists, several filter stages made of stainless steel mesh and additional HEPA H14 afterfilters are used for fine and carcinogenic particles. The stainless steel knitted filters can be easily and inexpensively washed out with a conventional high-pressure cleaner.

The cooling lubricants are collected in a container and can be fed back into the machining center. Due to the high filtration efficiency of the filters, the units are particularly low-maintenance and have a uniquely long filter service life. The cleaned air can then be returned to the production hall in recirculation mode or discharged outside as exhaust air.


  • High extraction performance with low energy consumption

  • Cleanable stainless steel mesh filter

  • The longest filter life in the industry

  • Reuse of the cooling lubricants

  • Quality directly from the manufacturer

When are oil mist separators used?

Oil mist separators are used to filter moist or sticky substances such as aerosol mist, emulsion mist or vapors generated during production processes. When machining workpieces, a coolant or cooling lubricant is often used, which is turned into a fine oil mist by heat (e.g. friction). These mists and emulsions are mostly hazardous to health, can damage machines and material, and contaminate workpieces. The risk of accidents and fire also increases significantly.

  • Occupational safety and health
  • Health protection
  • Fire hazard
  • Risk of accident
  • Environmental protection
  • Workpiece purity
  • Protection of machines and material
  • Compliance with legal regulations


What happens if I do not extract oil mist?

Due to the deposition of the fine oil film on surfaces, floors, walls and the hall ceiling, the fire hazard in the surrounding area increases considerably and the risk of accidents in the production hall increases. Employees can suffer short-term and long-term cognitive damage and respiratory illness when the fine aerosols and other harmful particles penetrate the lungs. Machines and tools are permanently contaminated and the quality of the workpieces decreases.

What are the collection options for oil mist collectors?

The extraction of the fine oil particles and other pollutants can be carried out via various capture systems. Important for the decision is the required air volume and the amount of emissions that need to be extracted and filtered.

Capture systems

  • Extraction arm
  • Extraction table
  • Extraction hood
  • Machine connection
  • Pipe system
  • Individual capturing system

What degree of separation is achieved by oil mist separators from ABSAUGWERK?

By using one to three filter stages, a separation efficiency of 99.998% can be achieved:

Filter stage 1
Stainless steel knitted filter Stage 1 Separation efficiency 99%.

Filter stage 2
Stainless steel knitted filter Stage 2 Separation efficiency 99%.

Filter stage 3 (optional)
HEPA H14 Filter separation efficiency 99.995%.

Filter stage 4 (optional)
Activated carbon filter

What air volumes can oil mist separators filter?

Oil mist separators from ABSAUGWERK can filter air volumes from 1,800 to 21,500 m³/h and can be individually configured and expanded due to the flexible system components. For large air volumes, several separators with separate fans can be connected in series, so there are no limits to our suction power. As a manufacturer, we also have the possibility to economically implement special solutions such as special captures or discharge variants. In the case of low hall ceilings, separate fans are also an option to ensure that the extraction system remains as compact as possible.

What is the engine power of the oil separators?

The motor power for the oil mist separator series ranges from 0.55 kW to 22 kW. Higher motor power can be achieved with a separate fan, these extraction units are called filter units in the industry and are also used for low ceiling heights. Here there is no limit to motor and air performance, as the filter units can be connected for in series.

Do the oil separators also run in recirculation mode?

The systems can be used in energy-saving recirculation mode or the purified exhaust air can be directed outside.

Are oil mist separator, emulsion mist separator and aerosol separator the same thing?

The most commonly used technical term in industry for extraction systems that filter oil mist, aerosols or emulsion mist is oil mist separator. Since the devices are also used as aerosol separators or emulsion mist separators, due to the similar particle size and oily/greasy nature of the particles, these are also common terms in extraction technology.

Oil mist separator function

The filter systems are usually connected directly to the respective machine, aspirate the media and filter them through several filter stages. The cleaned air can then be fed back into the room in recirculation mode or outdoors as exhaust air. The filtered emulsion drips off the metal mesh filters and is fed back into the processing center via a siphon hose. This saves material and costs.

Thanks to the adjustable air output and the integrated energy-saving motor, operating costs remain low. The extraction power can be individually adjusted to the respective process. The stainless-steel metal meshes can be conveniently clamped in the Cleanbox cleaning station and cleaned with a conventional high-pressure cleaner. The polluted water collects in a tub and is drained off via a drainage nozzle.

Low-maintenance oil mist extraction and long filter service life

As a manufacturer of extraction systems and oil mist separators, the quality of our systems has the highest priority. To ensure a long service life for our extraction systems, we install high-quality components and handle the entire service chain ourselves, from consulting to after-sales service. The installed metal mesh filters made of stainless steel can be washed out with a conventional high-pressure cleaner and separate oil mist so efficiently that the second and third filter stages are hardly affected. This significantly increases the service life of all installed filters and saves costs in operation and service. Each of our extraction units is individually tested and only leaves the WERK fully functional.
