Industrial processes often include machining and metalworking that release oil mist and fumes. These pose serious health risks to employees, damage equipment, and negatively impact product quality. A clean environment becomes necessary for increased productivity and enhancing product quality. This is where an electrostatic oil mist collector comes into the picture. This article will discuss all these mist collectors that will allow you to purchase the right one for your workshop or factory. Let’s dive in.

What is an Electrostatic Oil Mist Collector?

An electrostatic oil mist collector is an air filtration system specifically designed to remove oil mist, fumes, and other airborne contaminants generated during various industrial processes. These contaminants are often a byproduct of using oil-based coolants and lubricants in machining, grinding, and cutting operations. An electrostatic oil mist collector is often used in the following industries:

• Metalworking and machining
• Automotive manufacturing
• Food processing
• Aerospace and defense
• Chemical processing
• Woodworking shops
• Power generation plants
• Textile manufacturing

Now that you know what an electrostatic oil mist collector is, let’s look at how they actually work. 

How Electrostatic Oil Mist Collectors Work

An electrostatic oil mist collector follows a six-step process to filter the air in a facility. Check out the process below. 

• Intake

The first step is drawing in the polluted air containing oil mist. This is achieved using a powerful fan or blower that sucks the air into the collector unit.

• Pre-filtration

Some electrostatic oil mist collector may include a pre-filtration stage. This pre-filter traps larger dust particles before they reach the core collection system, ensuring optimal performance.

• Electrostatic charge  

In the third stage, the air passes through a section with high-voltage electrodes that create an intense electrical field. These electrodes cause the oil mist particles to become electrically charged.  

• Collection plates  

Oppositely charged collector plates are strategically positioned within the unit. Since the oil mist particles are now electrically charged, they’re strongly attracted to these oppositely charged plates. The electrostatic force pulls the particles out of the air stream and onto the collector plates.

• Drainage 

As the oil mist collects on the collector plates, it eventually drains down into a collection reservoir. This collected oil is often of good quality and can be recycled and reused in the machining process, promoting sustainability.

• Clean air discharge 

The final stage is the release of clean air.  Once the oil mist and other contaminants have been captured, the cleaned air is discharged back into the workplace, creating a healthier environment for employees.

Common Types of an Electrostatic Oil Mist Collector

Electrostatic oil mist collectors are primarily of two types, as mentioned below.

• Wet Electrostatic Oil Mist Collector

These collectors use a wet filtration process along with electrostatic charging. The incoming air stream is passed through a water bath or spray zone before reaching the charged collection plates.

• Dry Electrostatic Oil Mist Collector

As the name suggests, dry electrostatic oil mist collectors operate without the use of water. The oil mist particles are charged and collected on dry plates.

The Benefits of Electrostatic Oil Mist Collectors

An electrostatic oil mist collector has become important for factories, workshops, and other facilities that are prone to contaminants like oil mist and fumes. They have several benefits, like:

• These systems are highly efficient, with impressive removal rates. They are capable of collecting up to 99% of oil mist from the air, significantly improving the air quality. 
• Also, these systems are user-friendly and require low maintenance. The collector plates are typically washable and reusable, and the high-voltage components are generally reliable.
• An electrostatic oil mist collector is highly versatile and can be used in a variety of industrial settings, including metal fabrication plants, food processing facilities, and anywhere oil mist poses a challenge.
• By removing oil mist and other contaminants, electrostatic oil mist collectors significantly improve air quality, leading to a safer and healthier workplace for employees.  
• Lastly, improved air quality reduces maintenance costs for equipment and machinery, ultimately improving your bottom line.

Key Takeaways

Investing in an electrostatic oil mist collector is a wise decision for any business looking to create a cleaner, healthier, and more productive work environment. These powerful systems offer a cost-effective solution to tackling the challenges of oil mist, ensuring your workers have a clean working environment. So, find the right electrostatic oil mist collector for your facility and take a step forward to a healthier working environment.
