Advantage™ ThruAir® (TAD) Technology for structured tissue delivers the highest rate of absorbency with the lowest basis weight of any comparable tissue product on the market today. It is particularly suited for production of superior quality bath, towel and napkin grades from virgin or recycled pulp.
Highest absorbency to bulk ratio
Highest softness to bulk ratio
High machine efficiency
Highest production speed
Flexible for all kinds of ultra premium products of facial, bathroom tissue, towel.
Wide range of sheet basis weight and furnish strategies
TAD products have become the preferred choice for consumers around the world. Softness, strength, bulk and absorption are all highly valued products features. The Advantage Thru-Air (TAD) Technology provides these desired quality properties and can cater for all production volumes. The base principle of the TAD technology resides in vacuum dewatering of the sheet, molding of the sheet into a structured TAD fabric and drying the sheet by forced air.
The tri-dimensional fabric design and rush transfer capability associated with TAD manufacturing allow the tissue producers to dial-in sheet properties such as absorbency, bulk and softness. The TAD process avoids the destructive effect of wet pressing as opposed of other tissue manufacturing processes. This is key for a high bulk fully structured sheet.
In addition to all the normal conventional machine tools, the Advantage Thru-Air machines also offer the opportunities for rush transfer, molding, and a variety of TAD fabric styles. These all help to engineer a distinctive product with high consumer appeal.
Valmet continuously seeks for improving performance and efficiency of its Advantage Thru-Air technology with respect to fiber usage, fiber recovery, energy recovery and for reducing the emissions. The flexible design of the TAD air systems allows the manufacturer to adapt the technology based on energy cost, source of energy available or to minimize carbon emissions of the process.
The TAD technology can reduce fiber usage in the final product by up to 40% in comparison with a conventional tissue sheet depending on grade produced, fabric design and strategy of operation.
In comparison with conventional machines, Valmet TAD machines are known for the ability to deliver products with superior sheet properties and improved fiber utilization rates. This translates into higher value products with lower fiber costs per case. The numbers below are expected after converting operation.

The Advantage ThruAir 100 and 135 are entry level machines that are best suited for the small or medium sized producer or those exploring emerging markets.
For large scale producers in mature markets the Advantage ThruAir 200 can provide the very high output required. The concept is at the same time flexible and machines of varying width and output can be customized to suit producers’ special needs.
All members of the ThruAir family can produce top quality ultra-premium products. Further, energy consumption is as low as 3800 kWh/MT (depending of furnish/grade and operating conditions). This includes thermal (gas steam) and electrical.
