VentiBox

Improved removal of air moisture

The VentiBox hot air blow box is used for ventilating one- and two-tier dryer sections. It prevents the edge of the paper web from turning up and provides for better conditioning of the dryer fabric.

The VentiBox hot air blow box is connected to the air supply system within the machine frame or with a two-sided dryer section, also from the drive side. Via exhaust openings, hot dry air is brought into the dryer fabric and the pocket that absorbs the water vapor and reduces the air moisture. The air supply is increased in the center of the VentiBox, and the moist air is transported from the center of the machine to the edges. This transverse flow prevents the edges of the paper web from turning up. Condensation and hydrolysis are also prevented by the VentiBox.

The VentiBox hot air blow box is used in the one- and two-tier dryer section.
