DUO#DustCollect® Centrifugal Filter – Efficient filtration of fine dust down to dust class M

Highly effective dust filtration for industrial extraction systems – reduces fine dust exposure, extends maintenance intervals, and stabilizes your production processes.

Centrifugal filters are used when both fine dust particles and coarser particle fractions need to be reliably removed from the air stream. Fine dust, in particular, is generated in corrugated cardboard, printing, and paper processing, and cannot be adequately captured using pre-separators alone.
By combining centrifugal pre-separation with a downstream filter stage, centrifugal filters achieve significantly higher separation efficiency, even for small particle sizes. They are typically used in applications where there are high requirements for air purity, process stability, and operational reliability.

The DUO#DustCollect® centrifugal filters combine fine filtration and centrifugal separation in a coordinated integrated system. Coarser particles and paper debris are deflected outward by the centrifugal forces acting within the system and collected in the collection container. The dust-laden air stream is passed through the filter media, where fine dust particles are reliably captured.
This operating principle effectively removes both fine dust and coarse particle fractions from the air stream. Depending on the model, filter cleaning can be performed manually or automatically using compressed air, ensuring consistently high filtration performance during continuous operation.
The result is a compact and high-performance solution for dust filtration in industrial extraction systems. 

Reliable filtration of fine dust down to dust class M

• Combined pre-separation and fine filtration
• Consistent separation performance even during continuous operation
• Optional automatic filter cleaning
• Reduced dust levels in machinery and workshop air
• Extended maintenance intervals for downstream systems
• Flexible integration into existing extraction systems

The high filtration efficiency improves air quality in your production facility and sustainably increases process reliability.

DUO#DustCollect® centrifugal filters are used wherever both coarse particles and fine dust fractions need to be reliably separated.

Typical applications include:

• Corrugated cardboard production lines with high dust loads
• Flexographic and digital printing lines
• Centralized extraction systems in paper processing
• Post-press and converting lines
• Extraction of dust-intensive process steps

The centrifugal filter represents a powerful and economical solution, particularly for applications involving fine dust particles.

DUO#DustCollect® systems are available in a range of sizes and are customized within these models to accommodate specific air volumes, dust particle sizes, and plant layouts.

Typical design ranges

• Air volume: approx. 2,000 – 16,000 m³/h
• Particle sizes: from fine dust (dust class M) to coarse paper scraps
• Cleaning principles: centrifugal separation, filtration, or a combination
• Filter cleaning: manual (requires 6 bar compressed air connection) or automatic (requires 6 bar compressed air connection and 230V 50 Hz power supply)
• Integration: central or decentralized in extraction systems
• Retrofit capability: yes

Additional customer-specific configurations are possible.

A centrifugal filter is the right choice when fine dust particles need to be reliably separated. For applications involving mainly coarse paper particles and very high air volumes, however, we recommend using a DUO#DustCollect® Centrifugal Collector.
