An oil mist collector can be a powerful tool for capturing unbreathable mist generated by industrial machining processes to create a safer, healthier workplace. However, not all collectors are made equal. The performance and application of any given oil mist collector will depend heavily on the type of oil filtration system it uses.
In the realm of industrial safety and health management, selecting the appropriate oil filtration system is a critical decision that can significantly impact the operational efficiency and safety of your facility. In today’s article we delve into the various types of oil filtration systems, their mechanisms, and their applications, providing you with comprehensive insights to make an informed choice for your industrial facility’s next oil mist collector.
Understanding Oil Filtration Systems
While oil filtration systems are most commonly associated with machines like mills, lathes, and CNC machinery, they can also be found in oil mist collectors to remove contaminants from the collected process oil. These contaminants can range from solid metal particles to water and air bubbles, which can degrade the performance of machinery, reduce efficiency, and increase the risk of equipment failure. Filtering these contaminants out at the collection stage can help prep the oil for reuse. There are several types of oil filtration systems, each with unique mechanisms and applications.
Mechanical Filtration
Mechanical filtration is one of the most common methods used in industrial facilities. It involves the use of filters or sieves to physically remove particulate contaminants from oil. These systems can vary in complexity, from simple mesh filters to more sophisticated multi-layered filtration units.
Mechanical filtration is highly effective for removing large particles but may struggle with smaller contaminants. It is often used as a primary filtration step, followed by more advanced filtration methods.
Centrifugal Separators
Centrifugal separators utilize centrifugal force to separate contaminants from oil. These systems spin the oil at high speeds, causing heavier particles to move outward and be collected for removal. Centrifugal separators are highly efficient at removing both solid particles and water from oil, making them suitable for applications where high purity is required.
These systems are particularly advantageous in environments where the oil is heavily contaminated and requires frequent cleaning. However, they can be more expensive and complex to maintain compared to mechanical filters.
Electrostatic Precipitators
Electrostatic precipitators use electric fields to attract and capture contaminants from oil. These systems are effective at removing fine particles and even some dissolved contaminants, making them ideal for applications requiring high levels of oil purity.
Electrostatic precipitators are often used in conjunction with other filtration methods to provide comprehensive oil cleaning. Their efficiency in removing fine particles makes them valuable in industries where precision and cleanliness are paramount.
Oil Mist Collectors
Oil mist collectors, such as the FRED Carbo, Thunderbolt OMU, and our newest Aerity line are designed to capture and remove oil mist generated during industrial processes. Oil mist can pose significant health hazards to workers and cause equipment to malfunction. These collectors use various filtration methods, including mechanical filters and electrostatic precipitators, to remove oil mist from the air.
Oil mist collectors not only improve air quality but also help in recycling the collected oil, reducing waste and operational costs. Implementing oil mist collectors in your machining facility is essential for maintaining a safe, compliant, and efficient industrial environment.

Choosing the Right System for Your Facility
Selecting the appropriate oil filtration system for your facility depends on several factors, including the type of contaminants present, the required level of oil purity, and the specific industrial processes involved. Here are some key considerations to guide your decision:
Contaminant Type and Concentration
The type and concentration of contaminants in your oil will significantly influence your choice of filtration system. For instance, if your oil is likely to be contaminated with large particles, a mechanical filtration system may be sufficient. However, if fine particles or dissolved contaminants are present, a combination of centrifugal separators and electrostatic precipitators may be required.
Performance Requirements
Different industrial processes have varying requirements for airflow capacity and oil purity. Airflow capacity will depend on the rate at which contaminants like oil mist and smoke are generated. High-precision manufacturing processes, such as those in the aerospace or pharmaceutical industries, may necessitate ultra-clean oil. In such cases, advanced filtration systems like electrostatic precipitators are essential. One such machine would be the Thunderbolt, which is capable of achieving up to 99% oil purity on its own. Thunderbolt is also available with a wide range of airflow capacities from as little as 350 CFM to as much as 1,175 CFM. For even greater flexibility, the Aerity line features a modular design that’s been engineered to help you scale up at your own pace. Featuring units with a capacity as small as 600 CFM to as high as 2350 CFM, Aerity collectors can be mixed and matched for the ultimate level of customization and endless oil mist collection possibilities.
System Maintenance and Cost
The maintenance requirements and associated costs of the filtration system are also crucial considerations. Mechanical filters are generally easier and less expensive to maintain but may require frequent replacement. Centrifugal separators and electrostatic precipitators, on the other hand, may have higher upfront costs and maintenance requirements but offer superior filtration efficiency and longevity. If you’re interested in a mechanical system that is engineered for maximum longevity, check out FRED Carbo which features a dual-sided filter that can double filter life.

Real-World Examples and Recommendations
To illustrate the application of these principles, consider the example of a manufacturing facility that implemented the Thunderbolt OMU oil mist collector. This system effectively captured and recycled oil mist, improving air quality and reducing operational costs. Additionally, the facility employed a combination of mechanical filters and centrifugal separators to maintain optimal oil purity, ensuring the longevity and efficiency of their machinery.
Another example is a pharmaceutical plant that required ultra-clean oil for its precision equipment. By integrating electrostatic precipitators with their existing filtration setup, they achieved the necessary oil purity levels, resulting in improved product quality and reduced downtime.
Choosing the right oil filtration system for your industrial facility is a multifaceted decision that requires careful consideration of contaminant types, oil purity requirements, maintenance costs, and compliance with safety standards. By understanding the various filtration methods and their applications, you can make an informed choice that enhances operational efficiency, ensures equipment longevity, and maintains a safe working environment.
Implementing the appropriate oil filtration system not only contributes to the overall health and safety of your facility but also supports sustainable and efficient industrial practices.
