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
