Numbers that matter to us

6 000 000

According to the World Health Organization, up to 6 000 000 people die each year due to air pollution in the world. We are working for a cleaner and healthier world.

1 000

Our technology can clean gases in temperatures up to 1 000 degrees Celsius, where conventional Teflon-based filters do not work.


Our solution can be installed on site ready for use in just one working day, as it is serially produced in portable modular units.

Dust Removal as a Service

Because of the modular design of the solution, we are able to offer an alternative of Dust-Removal-as-a-Service to customers, entirely without the burden of investment and ownership.

For many applications, the energy savings from waste heat capture alone are enough to offset the cost of the service.

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.
