Through Air dryers are used for drying, curing, heat setting and thermal bonding of porous materials such as nonwovens, textiles, paper and fibers by the passage of heated air or gas through the material.

• 2 to 3 times higher Air flow (Heat Transfer) than conventional convection.
• Intimate contact with product interior heats uniformly and very rapidly.
• High thermal efficiency for Heating, cooling or Drying applications, with high
  evaporation rates from a combination of mechanical and thermal drying.
• Dependent on Permeability of the web and the conveyor.
• Wet to dry permeability changes in the web require multiple zones for efficient operation.
• In many thermal bonding applications such as auto carpeting, cotton shoddy and other recycled materials are mixed with low melt fibers such as Polyethylene.
