Oil mist separators

LOCAL CAPTURE AND EFFECTIVE FILTRATION

Oil mist separators are filter systems for extraction of oil mist and aerosols from the ambient air. For cutting and forming production processes in the metalworking industry, vapour, mist and fumes arise through the use of coolant lubricants. This arises firstly due to mechanical effects - through the vaporisation of cooling lubricant in quick-rotating tools (for example, when grinding or turning workpieces), and secondly through back condensation of vaporised cooling lubricants on hot surfaces. Warm workpieces stored in the open also pollute the ambient air with emissions. In theory, all surfaces coated with cooling lubricants (or contaminated work clothing, oil rags or floors) are to be seen as a source of emission. The warmer these surfaces, the more they contaminate the surrounding air. This increases the risk for employees in the immediate environment.

TESTED QUALITY

CERTIFIED PRODUCTS TO MINIMISE RISKS

The dust extractors are available with (IFA and TÜV) test certificates for special applications. This makes them usable in almost any application. Optionally, many dust extractors are also available in ATEX design. This makes them suitable for use in potentially-explosive areas (Zone 22).

PRODUCT OVERVIEW

For effective direct extraction of oil and emulsion mists and minimal lubricating musts and fumes, the OILMAC series is installed directly on the processing machine. 

As an alternative or supplement to direct extraction, the free-standing Plug & Play hall ventilation system FILTOWER is suitable. It captures dust, fumes etc without pipelines.

HAZARDS FOR EMPLOYEES

The cooling lubricant aerosols, fumes and vapours are absorbed by operators via their respiratory tract, digestive tract or via the skin. This can lead to a range of potential damage to the human body:

  • Irritation such as skin irritations, respiratory tract irritation
  • Changes to organs
  • Damage to the respiratory tract
  • Mutagenic effects
  • Carcinogenic reactions
     

MECHANICAL FILTRATION

The OILMAC oil mist separator developed by ESTA works with a mechanical filtration unit. A 3-stage filter system, comprising pre-separator, main separator and follow-up filter is used. This achieves a filtration efficiency of 99.95 %. Thus the safety of workers and the processing machine itself are guaranteed. 
The OILMAC oil separator are used in grinding machines, processing centres, turning machines, milling machines, cooling systems, honing machines, lapping machines or spark erosion machines. 
 
 

The OILMAC is installed directly on the housing of these machines as a space-saving measure or next to them and connected via a pipelien or extraction hose. The right way to configure this filter system is one of the most complex issues when working with cooling refrigerant emissions and must always be undertaken by an expert.

In general, cooling lubricant emissions in the machine hall can be reduced in three ways:

  • Prevent the origin of emulsion mists, oil mists and oil fumes
  • Capture and extraction of unpreventable aerosol mists and oil mists via an oil mist separator
  • Sufficient hall ventilation
     

Important for improving aerosol mist, oil smoke and -vapours is the choice of the right cooling lubricant in workpiece machining. Often too small an amount of cooling lubricant is used on the workpiece or the wrong cooling lubricant. Also make sure the processing machine and oil mist separator is serviced regularly. Warm, wetted workpieces should be stored in closed containers. Avoid storage in the open. The tool machine itself should be fully encapsulated where possible to prevent emissions from escaping.

Know-how for clean air at the work place.

In around 200,000 metal firms in Germany, metalworking fluids are in use - employees come into regular contact with substances potentially harmful to health. For this reason, the German Association of Machine and Installation Construction (VDMA) e.V., devised the "Metalworking Fluids - Air pollution control” guide.
