Different Types of Mist Collectors and Their Applications

In industrial settings where machining, grinding, or cutting operations occur, the generation of mist and aerosol contaminants is common. These airborne particles can pose health risks to workers and lead to declining air quality within the facility. Mist collectors are specialized devices designed to remove mist, aerosols, and other fine particles from the air, ensuring a cleaner and safer working environment. This article provides an overview of the different types of mist collectors available and their specific applications.

Centrifugal Mist Collectors
Centrifugal mist collectors, also known as inertial separators, utilize the principles of centrifugal force to separate mist particles from the air. This type of mist collector is commonly employed in various industries due to its efficiency and versatility.

1. Principle of Operation:

Centrifugal mist collectors direct the contaminated air through a series of baffles or vanes. As the air enters the mist collector, the centrifugal force causes the mist particles to move toward the outer walls of the collector. The separated mist drains into a collection reservoir, while the cleaned air is discharged back into the environment.

2. Applications:

Centrifugal mist collectors effectively remove coolant mist, and other water-based mists. They are commonly used in metalworking operations, such as machining centers, grinding machines, and parts washers. Centrifugal mist collectors are also suitable for applications involving the production of fine powders and dust particles.

Electrostatic Precipitators
Electrostatic precipitators (ESPs) are mist collectors that employ an electrostatic charge to remove mist particles from the air. They are particularly effective in capturing submicron particles and are widely used in industries with stringent air quality requirements.

1. Principle of Operation:

Electrostatic precipitators use an ionization process to charge the mist particles as they pass through an ionization section. The charged particles are then attracted to oppositely charged collection plates or tubes, where they adhere and are subsequently removed from the air. The cleaned air is discharged back into the workspace.

2. Applications:

Electrostatic precipitators are suitable for oil mist, smoke, and fine particulate matter applications. They are commonly used in metalworking, chemical processing, and pharmaceutical manufacturing industries. ESPs are highly efficient in removing hazardous contaminants and maintaining a clean and safe working environment.

Key Points

Here are three key points to consider when choosing the right mist collector for your specific application:

1. Airflow and Filtration Efficiency:

Different mist collectors have varying airflow capacities and filtration efficiencies. It is important to assess the volume of mist generated in your facility and select a mist collector that can effectively handle the anticipated airflow while providing the desired level of filtration efficiency.

2. Maintenance and Serviceability:

Regular maintenance is crucial for the optimal performance of mist collectors. Consider the ease of maintenance and availability of replacement filters when selecting a mist collector. Additionally, ensure that the mist collector’s design allows easy access and cleaning to minimize downtime and maximize productivity.

3. Compatibility with Applications:

Different mist collectors are designed to handle specific mist types, aerosols, or particulate matter. Assess the nature of the contaminants in your application and choose a mist collector that is specifically suited to handle those contaminants effectively.


Mist collectors play a vital role in maintaining a clean and safe working environment by removing mist, aerosols, and fine particles generated during industrial processes. Understanding the different types of mist collectors available, such as centrifugal and electrostatic precipitators, is essential in choosing the right solution for your specific application.
