Oil Mist Extraction

Process Industry

METU-FORM for the Process Industry

Ventilation ducts for metal working installations and production sites: extraction of oil mist, coolants and emulsions, machine hookups.

Applications

Machine tools, metalworking, rolling mills, CNC machining (turning, cutting, milling, grinding, drilling), process Industry, metalworking, industrial plants, production facilities, automotive industry.
Suction systems for aerosols (oil mist) and cutting fluids,  extraction of welding steam and  fumes.
Industrial plant builders, design offices, architecture firms.

Work Safety

Oil mist pollutes the workplace (www.baua.de), can generate health problems over the long-term (respiratory infections, accidents due to slippery floors) and may even affect other manufacturing processes.
Thanks to the METU-FORM, complicated and often questionable improvements in an attempt to make the air ducts oil-tight belong to the past (see references).

 

Common Problems

 

Spiral seam ducts are not ideal for the process industry, as they are usually not oil-tight over the long term.

 

Such connections are no exception

Solution

 

The METU-FORM system offers an optimal solution that does not require any additional sealing measures. (Click on the image to enlarge it)

The METU drain fittings ST-K allow to remove any liquids (condensation, oil, etc.) which might have accumulated in the air ducts. 

 

Inclined Air-ducts

It is recommended to install the ducts with a certain gradient (slope) in order to allow liquids (condensation, oils, liquid detergents, emulsions and other liquids used in metal working processes) to flow towards the drainage points (see also the drain fittings and special elbows).


1.   90° Elbow minus about 3°
2.   Spacial 3° degrees ebow
3.   Elbow with a non-standard angle
4.   Slope
5.   Drain fitting ST-K
6.   Oils (process industry), condensation, liquid detergents (Kitchens), etc.

 

The oil stays inside the METU-FORM air-ducts. The drain fittings ST allow to remove the oil or condensation at selected locations.

Resistances to Chemicals

Chemicals and oils are available in very different qualities. Their properties vary depending on their concentration, operating temperatures, possible mix with other chemicals and the eventual presence of impurities.

This is why gasket manufacturers only provide general information about the resistance of their products to various chemicals.

Is is therefore necessary to ask your suppliers of oils, solvents and other chemicals which materials (galvanized steel, stainless steel, etc.) and which gaskets (PE, EPDM, NBR, Silicone, etc.) they recommend. 

In view of the above it is advisable that the client runs some tests in order to assess if the gaskets are suitable for the intended application.
