Ducted Air Cleaners

Ducted Air Cleaners are designed to help capture and filter airborne contaminants through a connected ducted system in industrial and commercial environments. They are commonly used in applications where dust, smoke, mist, or gas-phase contaminants need to be managed using application-specific filtration rather than a one-size-fits-all approach. These systems can be configured with different filter types, including particulate, mist, and gas-phase media, and may be supplied with or without pre-engineered fan packages.

These systems are often used where contaminants are generated at defined pickup points and must be conveyed through ductwork to a centralized or dedicated air-cleaning unit. Depending on the application, Ducted Air Cleaners may be used for welding fumes, grinding dust, mist, VOC-related processes, 3D printing, laboratory work, and other operations where the contaminant profile determines the filtration strategy. The best fit depends on the contaminant, required airflow, duct layout, filter media, and whether the system is being used for particulate, liquid, or gas-phase control.

What are Ducted Air Cleaners?

Ducted Air Cleaners are filtration systems connected to hoods, pickup points, or enclosed process areas through ductwork so contaminated air can be captured, transported, and cleaned before discharge or recirculation. Depending on the design, they may use HEPA filtration, mist agglomeration, gas-absorption media, or other filter arrangements selected to suit the process. They are typically chosen when a facility needs more tailored filtration and a ducted layout rather than relying only on portable or ambient room-cleaning equipment.

When should you use Ducted Air Cleaners?

Ducted Air Cleaners are typically used when contaminants are generated at identifiable source points and the filtration method must be matched closely to the pollutant being handled. They may be a strong choice for facilities managing welding smoke, grinding dust, mist, VOC-related emissions, or mixed-process air streams where source capture is needed along with more specialized filtration. The best fit depends on the process, required capture and transport velocities, system resistance, filter compatibility, and whether a pre-engineered or custom fan arrangement is more appropriate.

Typical applications

• welding and fabrication
• grinding and finishing
• mist-producing processes
• VOC-related or gas-phase applications
• 3D printing environments
• laboratory and technical work areas
• repair and maintenance operations
• process-specific ducted air-cleaning projects

Key benefits

• supports application-specific filtration for particulate, mist, and gas-phase contaminants
• connects to ducted capture points for more integrated contaminant control
• available with or without pre-engineered fan packages
• suited to a wide range of industrial and commercial processes
• can be configured for different airflow requirements and filter arrangements

Important selection considerations

When selecting a Ducted Air Cleaner, key factors may include:

• contaminant type and concentration
• required capture, transport, and face velocities
• duct layout and system static pressure
• particulate, mist, or gas-phase filter requirements
• airflow volume and fan selection
• maintenance access and filter replacement intervals
• compatibility with the process and working environment
• whether the system will be used for source capture, enclosure exhaust, or broader ducted air cleaning

The right Ducted Air Cleaner depends on how and where it will be used. LEV-CO can help review your process, contaminant profile, airflow requirements, and filtration needs to recommend a practical solution for ducted particulate, mist, and gas-phase air cleaning.
