Herding GmbH Filtertechnik

Herding GmbH Filtertechnik is a manufacturer of filter media, dust collecting systems and filter systems for industrial use. Within a period of 40 years the filter specialist Herding® Filtertechnik has developed into a global supplier of complete systems for all sectors of industry.

Profile Description

In additive manufacturing of metallic materials more and more attention is being paid to safety aspects. In recent years, the further development of AM plant systems has focused primarily on optimizing core processes, the materials to be used and functionality. Currently, the focus is on maximum safety in handling the highly reactive materials and ensure sustainable operational consistency, especially in peripheral processes such as filtration and passivation technology.

The use of pure surface filtration with the Herding® Sinter-Plate Filter in combination with the safest consistent passivation and integration into the inert gas circuit of the systems offers an optimum solution.


Herding® Filtertechnik offers tailor-made and specifically developed filter unit designs from prototype to series production in order to increase productivity and safety on the basis of:

Gas-tight filter systems with the Herding® Sinter-Plate Filter
Automated passivation unit
Integrated vacuum generator
Autonomous control system
Individually adapted enclosure if necessary
All areas of additive manufacturing are covered, such as.

Metal powder production
Additive manufacturing of parts
Powder transport systems
Post processing of parts
Herding®Filter Elements
The heart of Herding technology is the filter medium, which is the ideal companion for additive manufacturing processes.

Operator benefits through the filter medium:

Pure surface filtration enables absolutely constant operating conditions
Minimum influence on the laminar flow
Highest separation efficiencies < 0.1 mg/m³ – Optimum protection of downstream units
Extremely long service life due to the properties of the rigid body medium
No filtration-related wear of the filter media
