Walair specializes in the design and supply of equipment that utilizes air technology to separate material fractions and/or prepare them for further processing, such as sensor based sorting.

Walair’s 2-way, 3-way, and 4-way Density Air Separators provide maximum separation of mixed waste, C&D, and MSW streams at very high capacities.

Walair Products:

  • Drum air separators in 2 – 3 – 4 density / shape fractions
  • Wind shifters in combination with rotary material separators
  • Over belt suction sort systems
  • Dust extraction systems
  • Vacuum suction separation systems

Examples of Application:

  • Divert material streams in different densities to improve post sorting efficiency
  • Air density separation to eliminate shredder damage in RDF processes
  • Volume reduction to improve performance of post sorting equipment
  • Over belt suction sort to improve sorting efficiency of light fraction sorting (film sorting)
  • Dust extraction system to improve air quality
  • Air systems integrated in mechanical sorting units (PaperMagnet® and ONP screens)

Walair Density Air Separator Advantages:

  • No material is transported through duct lines (eliminating blockages and wear in duct lines)
  • High accuracy density separation due to maximum adjustability of the separating airstream
  • Large variety of material can be handled
  • Large volume capacity due to high air transport speeds
  • Low maintenance costs

  • MSW
  • RDF
  • C&I
  • C&D
  • Comingled
  • Car shredding systems
  • Aggregate & glass clean up systems
  • Biomass clean-up
  • Compost clean-up
  • Incinerator slag recovery systems
