Three Types of Oil Mist Collectors For Industrial Metalworking

Three Types of Oil Mist Collectors For Industrial Metalworking

Metalworking shops use different types of CNC and traditional cutting and grinding machines. These machines use fluids to minimize friction, provide cooling effects, and prolong the life of the equipment. As important these machines for their day-to-day operations, they can cause indoor pollution within the facility by releasing harmful oil mists. When exposed to high temperatures, the oil starts to burn, turns into smoke, and emitted into the air. That is why it is important to equip these CNC machines with the right oil mist collector system.

What are Oil Mist Collectors?

Every day, millions of fine oil mists are released into the air by metal cutting machines.

Mist collectors are devices designed to filter the air by removing harmful oil mist from CNC machines, grinding, and milling processes and provide clean and breathable air inside the facility. Its function is not simply limited to collecting oil mist; it is also used to collect and filter machines that release coolant mist and water mist to keep the machine surfaces and facility floors dry and clean.

Why Install a Mist Collector

Oil mist collectors protect workers from the harmful effects of oil mist.

Installing a mist collector system helps ensure the health and safety of workers by complying with the government regulation restricting oil mist exposure, thus reducing working lawsuits and liability. Oil mist exposure can cause skin and eye irritation, skin and respiratory diseases, difficulty in breathing, fever, vomiting, fatigue, rapid heart rate, and burning sensation in the mouth, throat or stomach. Worst-case scenario, workers can be at high risk of life-threatening disease, like cancer.

Occupational Safety and Health Administration (OSHA), National Institute for Occupational Safety and Health (NIOSH), and Association Advancing Occupational and Environmental Health (ACGIH) issued a limited amount of oil mist exposure to protect the safety and health of your workers. Failure to comply with OSHA’s guidelines can result in fines.

Take a look at the chart given below:

OSHA Permissible Exposure Limit NIOSH Recommended Exposure Limit ACGIH Threshold Limit Values
5 mg/m3 over 8 hour/day, 40 hours/week 5 mg/m3 at 10 hour/day, 40 hours/week

10 mg/m3 ST – 15 minute period

5 mg/m3 over 8 hour/day, 40 hours/week

The Three Types of Industrial Mist Collectors

Installing an oil mist collector keeps your machine working efficiently.

Oil mist problems can be easily identified. In many cases, oil residues are evident on various surfaces, including machinery, walls, floors, and lights. Oil mist emits a distinct odour that confirms the problem.

However, having a reliable and high-quality oil mist collector system in problem helps eliminate oil mist problems. Consider installing one of these oil mist collector systems to keep CNC machines and the facility clean and oil mist-free.


  • Centrifugal Mist Collectors – Originally manufactured and designed for nuclear submarine gearboxes. Centrifugal mist collectors can be mounted on top of the machining centres or floor surfaces to filter coolant mist, smoke, gas, and Its rotating filter system helps trap fine mist droplets and turns them into larger droplets. Its complex mechanical system depends on centrifugal high-velocity force which thrust the liquefied oil outward from the centre of the device to flow along the walls of the machine to a dedicated drain.
  • Cartridge Mist Collectors – Also known as media filter mist eliminators, cartridge mist collectors come with a high-efficiency particulate air (HEPA) filter to effectively remove industrial smoke and oil mist from the air. It comes with a fan or blower that forcibly draws the coolant mist and oil smoke into the cartridge. The fine, hazardous particles forcibly pass through the HEPA filter where oil mist and droplets are filtered out of the existing air.
  • Electrostatic Precipitator Mist Collectors – This type of oil mist collector uses high voltage electricity to charge, filter, and collect fine oil mist and smoke in industrial applications. It works by generating a positive change on the liquified particles carried by the air current. The air carrying the positively charged particles creates attraction as it passes between a series of negatively charged plates. This causes hazardous particles to stick to the plate and eliminated from the airflow.


Benefits of Installing an Efficient Oil Mist Collector System

Oil mist collectors help you save money on costly maintenance and repairs.

Air quality plays a significant factor in the success of your business. Responsible business owners understand the importance of employee health and safety and the need to protect them from the dangers inherent to industrial environments. Installing an efficient oil mist collector system comes with some great benefits, including:


  • Reduced Maintenance and Downtime – Installing oil mist collector systems on the CNC machine gives you peace of mind by minimizing maintenance needs and downtime. Without mist collectors, oil and dirt can cause damage on circuit boards and clog up the filters of the cooling systems. Over time, this blocks the airflow and cause system failure and other performance issues. When oily dirt starts to accumulate, the temperature rises and prevents the system from protecting electronic components, such as power supplies, drives, control systems, and monitors.


Additionally, when oil mist seeps into the coolant pump systems, it creates a thriving place for bacteria that damage the motor pump seals and corrodes the metallic electrical components.


  • Improved General Safety in the Shop – Oil mist collectors ensures that no oil mist escapes when you open the CNC machine doors when loading raw materials and removing finished products to keep the floors, lighting, counters, and walls clean and dry. In addition to dimmer lighting and cleanliness concerns, oil mist can create slip and fire hazards.


Keep your metalworking shop clean to prevent workplace accidents.

With the growing trend in high-speed machining use, many industries use equipment that creates finer oil mist and smoke that are harmful to your worker’s health. But with the latest developments in filter technology, it significantly helps reduce contamination problems and improves air quality within metalworking facilities.
