The devices in the LN 600 series feature a large filter area, providing a long service life. They can be equipped with different filters at the factory to meet individual application requirements. The special high-power blower gives the systems a high effective air flow rate, allowing them to be used in decentralised positions for multi-site extraction.


  • Soldering (multi-site extraction)
  • Laser processing
  • Processes for working with adhesive/moist dusts
  • Processes for working with vapours/gases

Functional Principle

The contaminated air is collected by the collection unit (extractor hood, suction arm, hose, etc.) and transported into the filter unit directly or through a pipe or flexible hose. In the filter unit, the contaminant particles are filtered into different filter levels according to their size. Filter units that are equipped with a molecular sieve (for example activated carbon filters/BAC) remove the majority of gaseous contaminants. Afterwards the purified air can either be circulated back into the work area or diverted outdoors through an exhaust duct. Recirculating the air in the work area is a way to easily reduce energy costs.
