Air Filtration for Neat Oil Machining – When to choose ESP?

Neat oil machining involves the use of lubricating oils without emulsions, and this process can generate mist and smoke that need to be effectively managed for the well-being of workers and the maintenance of equipment. Selecting an industrial filter for neat oil machining requires a comprehensive understanding of the specific requirements and challenges of the application.

When deciding between a mist collector and an Electrostatic Precipitator (ESP), several factors come into play:

When to choose ESP? 

ESP Efficiency of Particle Removal

ESPs utilize an electrostatic charge to attract and collect mist and particles. As a result, ESPs are effective in filtration of sticky oil particles, even of finer size. They utilize electrostatic forces to capture and remove fine oil mist and particulate contaminants from the air, achieving high filtration efficiencies . This makes ESPs a reliable choice for maintaining clean air quality and preventing environmental contamination in the machining industry.

Particle Size and Type

Consider the particle size distribution and nature of particles generated during neat oil machining.

ESPs are fully capable of capturing both the coarser and finer particles that might escape from filters working on alternate filtration principles.

Maintenance and Operating Costs

ESPs (Electrostatic Precipitators) offer a favorable balance between maintenance and consumable costs. While ESPs do require regular maintenance to sustain filtration efficiency, their distinct advantage lies in the minimal to no filter replacement costs. ESP can be cleaned and reused, significantly reducing ongoing consumable expenses and making them a cost-effective choice for industries where long-term efficiency and cost savings are paramount.

Environmental Concerns

ESPs’ reusable filters reduce the generation of filter waste, aligning with sustainable practices and reducing the environmental burden of disposal. The durability and long service life of ESPs mean fewer replacements, reducing the overall environmental impact associated with manufacturing and disposal of filtration equipment.

Particulate Concentration

If the neat oil machining process produces a high concentration of fine particles or smoke, ESPs are equipped to handle such conditions.

Longevity and Durability

ESPs are known for their robustness and durability, making them suitable for industrial settings with heavy-duty requirements.

ESPs from SFS offer several benefits in air filtration for neat oil machining

Neat oil machining often produces a wide range of particle sizes, including fine mists. ESPs are capable of capturing these finer particles effectively due to their electrostatic attraction, ensuring cleaner air quality. Also, ESPs excel at removing a broader spectrum of particles, from coarse to fine , making them well-suited for the diverse emissions generated by neat oil machining.
