What is Centrifugal Industrial Extraction?

Centrifugal Industrial Extraction is used in industrial and manufacturing environments to remove oil mist, as well as the continuous extraction of a particular liquid phase into another one. This method is very effective and mainly uses high quality centrifugal fans.

Substances that are removed through the process of Centrifugal Industrial Extraction include:

  • Fumes
  • Dust
  • Vapours
  • Gases
  • Fibres
  • Mist

All these substances directly affect the air in most workplaces and mainly contaminate it. This means that most workplaces should try to use the centrifugal industrial process to try and get rid of these contaminants present in the air.

How does the process work?

Typically a perforated drum is used, with vanes that are able to rotate at a very high speed. Once the oil mist is slowly drawn into the unit, it is able to hit the vanes at a very high velocity. Synthetic pads then play a major role in collecting solid particles.

The Centrifugal Industrial Extraction process uses centrifugal force which is able to provide force to the oil and push it to the outer case of the unit. The oil is then able to drain back to the machine where it is collected or reused. The clean air is then collected and pushed back out into the environment.

Why is Centrifugal Industrial Extraction important?

Industrial extraction of particulates plays a major role in ensuring that air cleanliness levels are maintained, reducing the likelihood of respiratory diseases caused by breathing in polluted air.

In the UK, all industrial workplaces should ensure that all their employees work in environments that are free from any health hazards like contaminated air.

Benefits of using centrifugal fans for extraction

These centrifuge fans can operate effectively in environments that have both high pressure and extreme temperatures.

The diameter of the wall units mainly ranges between 500 to 1000mm. The diameter of the roof units typically ranges between 630 to 1400mm. The capacity of these units is approximately 30m3 for every second that air flows in. This particular extraction process can  be customised to ensure that it meets all your requirements.

Chambers in this form of extraction

  • Mixing chamber: The mixing chamber mainly comprises two phases that are well mixed. The solutes that are going to be extracted are mainly transferred in this chamber. An emulsion is also formed when the two phases are thoroughly mixed.
  • Decanting chamber: Centrifugal force is mainly used to try and separate the two fluids that are well mixed here.

Sourcing the best fans for the job

For this type of extraction to take place, you should always ensure that you get high quality centrifugal fans from good manufacturers. This type of industrial extraction is important as it helps in maintaining clean and fresh air, playing a major role in safeguarding the health of all individuals in your workplace.
