AtexDeDust- filter for small particles

Filter test rig

AtexDeDust AtexDeDust is a partnership of European SMEs that have identified a promising new design and functionality for air cleaning systems in industrial scale.

The proposal addresses dust/air systems according to the ATEX Directive for systems with hazard of explosive atmospheres as well as standard applications in a wide range of production lines.

Especially we focus on smart, mobile instrumentation to meet the demands of modern production management. This new technology will guarantee safe air pollution control inside production estates and in the output to environment One main feature to reach this objective is the use of a improved textile filter material with manifold air permeability.

This succeeds in a diminishing of the pressure loss about the filter layer thereby reducing energy consumption for a wide size of particulate in air and gases. It overcomes the risks of potential explosive atmospheres of dust concentration inside the housing during the periodic regeneration process of the filter elements. Though it allows mobile instrumentation in smarter size, supply with common electric and electronic components and a better filtration performance compared to the state of the art.

The new air cleaning systems has potential to be of significant commercial benefit to producers in the common application fields and in new ones with nano-scale material use. To successfully develop this technology that will be both of economic benefit to ourselves and to a wider number of SME companies in Europe, we have identified that we need the support from external Research and Development resource and financial support from the EC under the Research for SME program. Combining new approaches in air flow pattern, in filter design, in new cleaning method to dislodge the dust cake from filters and in sophisticated filter material, it will increase the performance of the filtration system.
