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 turns into a fine oil mist due to heat (e.g. friction). These mists and emulsions are generally hazardous to health, can damage machines and materials and contaminate workpieces. In addition, the risk of accidents and fire increases considerably.

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

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

Fine oil particles and other pollutants can be extracted using various collection systems. The required air volume and the amount of emissions that need to be extracted and filtered are decisive factors in the decision.

Capture systems

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

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

Filter stage 1
Stainless steel mesh filter with a separation efficiency of 96–98%

Filter stage 2
Stainless steel mesh filter with a separation efficiency of 99

Filter stage 3 (optional)
HEPA H14 filter with a separation efficiency of 99.995%

Filter stage 4 (optional)
Activated carbon filter

The oil mist separators from ABSAUGWERK can filter air volumes from 1,800 to 21,500 m³/h and can be individually configured and expanded thanks to the flexible system components. For large air volumes, several separators with separate fans can be connected in series, which means there are no limits to the extraction capacity. As a manufacturer, we are also able to implement special solutions such as special captures or discharge variants economically. Separate fans are also suitable for low hall ceilings in order to make the extraction system as compact as possible.

The motor power for the oil mist separator series is between 0.55 kW and 22 kW. Higher motor outputs can be achieved by using a separate fan. These types of extraction systems are known in the industry as filter units and are also used for low ceiling heights. There is no limit to the motor and air output, as the filter units can be connected in series.

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

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