Oil Mist Extraction

Oil mist local exhaust ventilation (LEV) systems are used for the capture of metalworking fluids. Oil mist extraction units are ideal for extracting the mist and fume generated from metal cutting processes such as lathe turning, milling, drilling, wet grinding and spark suppression (not oil smoke).

 

Why Do I Need Oil Mist Extraction?

Metalworking fluids are used as a lubricant or coolant to keep parts from wearing. However, one of the inevitable by-products of pumps, compressors, turbines and other machines using oil is oil mist.

Oil mist inhalation is a health hazard, so having it disperse into the workplace reduces the air quality. and can also damage the environment if released into the atmosphere. It can settle and coat machinery and has the potential to increase the risk of potential equipment breakdowns. Droplets can also settle on products, staining and potentially contaminate a product making it unusable.

There's also cost savings to benefit from by having an oil mist filtration systems, as oil that escapes as mist can be captured, filtered and reused.

Oil mist eliminators (or oil smoke filters) extract the oil mist from the immediate vicinity of the machinery, which can benefit your staff, your products, your machinery and your business in a variety of ways.

Oil mist extraction systems are capable of eliminating up to 99.5% of oil particulates from equipment discharge. Oil mist extractors operate in a three or four-stage filtration system with replaceable elements. Oil collected by the filters can then be returned to the system, reducing oil waste and cutting operating costs. Particulate filters and activated carbon filters can also be added to the local exhaust ventilation LEV system to process and remove odour in the air stream.

The filter is built with the modular principle in mind and can easily be expanded to accommodate additional modules. Oil mist filter units have an airflow ranging from 400m3/h to 8,000m3/h with two or three-stage filtration options.``

1. Inlet - Optionally left or right.
2. Base filter - Fibreglass filter with aluminium separators EU5. Should be replaced at a pressure of 500 Pa.
3. Fine filter - Fiberglass filter with aluminium separators EU9. Should be replaced at a pressure of 500Pa.
4. HEPA filter H13 - Filtration level greater than 99%, not washable but easily replaceable. Should be replaced at a pressure of 800 Pa.
5. Fan
6. Drainage left or right.

Oil mist extraction systems remove oil and emulsion mist that is produced when sprayed on to the workpiece during drilling and boring processes. They're sprayed on to the machine tool equipment to cool the metal down from the high temperatures produced.

LEV systems need to be meticulously planned to ensure the airflow extraction rates for oil mist removal is achieved. They extract away any oil mist droplets and the fume.

What do the HSE State?

HSE have recently launched a number of new COSHH essential guidance documents to help businesses and duty holder protect employees from metalworking fluids. These can be found on their main Metalworking Fluids page. On here, you'll find a variety of different documents, including Advice for Mangers, CNC Machining, Control of Skin Risks During Machining, Sump Cleaning: Water-mix Fluids, Sump Cleaning: Neat Oils and Managing Fluid Quality.

In the HSE's MW1 - COSHH Essentials for Machining and Metalworking Fluids: CNC Machining guidance, it recommends businesses should: "Enclose the machine in as much as possible, for example, retrofit roof panels" and to, "Provide local exhaust ventilation (LEV) to the enclosure. This can either be a standalone unit or a centralised system linking two or more machines. 

Whilst in HSE's RR1044 Report: Consultation on Monitoring of Water-miscible Metalworking Fluid (MWF) Mists, discusses the link between the control of metalworking fluid mist and the reduction of respiratory ill health in machining workers, which been a concern of manufacturers who employ metalworking fluid processes. It goes on to say: "How the use of enhanced local exhaust ventilation systems will help minimise the risk. These typically come in the format of oil mist filter units which catch oil droplets from the working process.

 

Evolution of HSE's Metalworking Fluid Guidance

HSE's COSHH essential guidance has come a long way since, older 2011 and 2016 versions. They've become a lot more robust and thought out, some key difference includes:

  • Highlighting the hazard of escaping mist when CNC machine doors open too soon after machining stops
  • Controlling the risk to skin, as well as to respiratory risks
  • Enclosing CNC machines via retrofitting roof panels
  • Stating the method for determining the time delay on enclosed machinery
  • Alternative methods to cleaning components via air guns and what to do if air guns are unavoidable
  • A better definition of a competent person when it comes to the LEV system documents and testing
  • Measures to check the effectiveness of controls are noted as a dust lamp/DRAMS. Also, monitoring the metalworking fluid quality. However, in the new version of MW COSHH essentials guidance, there's no mention of Workplace Air Monitoring, which had been mentioned in previous versions
  • Health surveillance for dermatitis, as well as occupational asthma
  • IIT to specifically include the understanding of how the LEV system work, how to check whether it's working, when to use air gun alternatives and how to use air guns in a way that minimises exposure.

 

What are the Health Risks of Oil Mist Exposure?

HSE state: "Exposure to metalworking fluids can cause; irritation of the skin/dermatitis and lung diseases, such as occupational asthma and occupational hypersensitivity pneumonitis. Metalworking fluid systems that contain water or water mixes can become highly contaminated with harmful bacteria, such as legionnaires disease. The bacterial contamination of fluids and associated machinery and pipework should be monitored and controlled."
