Flow-dynamic dust separation

Filtrabit’s patented innovation is based on flow dynamics. The technology enables industrial clients to reduce their PM2.5 emissions to meet strict regulation and health standards.

The modular units are serially manufactured and portable, allowing for one-day installation without the need for building permits – as well as exact tailoring and retrofitting of capacity.

Instead of traditional baghouse technology, that is vulnerable to clogging and tearing, Filtrabit’s solution is built from steel capable of handling extreme temperatures. It can be operated continuously, with practically no need for maintenance.

Watch the video below for a quick conceptual view of the technology.

Material and energy efficiency

Filtering hot gas flows

Allows customers to recover heat and rapidly repay the investment.

Separated material

Can be recovered for reuse for further economic and environmental benefits.

No changing of filters

Means less waste generated and lower total cost of ownership.

Modular design

  • Superior logistics and installation speed: up to one-day plug and play.
  • Flexible placement: no building permit required. Industrially manufactured, serially produced.
  • More units can be installed parallel for just the right capacity.
  • A replacement unit can be brought on site if another is undergoing maintenance.
Filtrabit units are modular, making capacity easy to scale.
Filtrabit's solution includes the capability of smart sensors.

Smart solution

  • The Filtrabit device is capable of continuously collecting functional data in the cloud for analysis.
  • It enables predictive maintenance: algorithms can notice abnormal trends well in advance of issues.
  • Able to monitor the industrial plant’s production process and changes to it by measuring various data points.

Conveyor dust comparison example.


Flow-dynamic dust separation is the new standard for industries that generate heavy, dry and fine dust from sand, dusty material handling, slag, welding, metal grinding and cutting operations with laser or gas, etc.

Examples of customers include steel mills, foundries, machine shops, factories, power plants and stone processing companies.


Coking plants at steel mills are prime examples of high dust producing environments where the ability to filter hot gas flows provides significant savings and carbon emission reduction.


Multiple stages of the cement making process produce dust and other particulate matter, including the handling of sand and high-temperature kilns. Recovered dust can be immediately reused as raw material.

Power & Heat

Burning of coal, waste or other fuels for power and heat production generates large volumes of particulate matter, often near population dense areas, that need to be effectively filtered.

Mining & Quarries

Working with stone necessarily produces a lot of heavy dust, with even greater demand for modularity and portability due to operating in an environment that is changing over time.
