The traversing DuoCleaner Express is equipped with up to six concentrated, high-pressure cleaning jets that spray water on the dryer fabric at a defined angle. Water jet injectors in the cleaning head generate a vacuum, which together with the connected mill vacuum system ensures that the deflected water and contamination is removed from the cleaning zone. A small amount of water from the cleaning jets goes through the fabric and is collected and removed in an optional tray under the dryer fabric. In addition, an air knife blows residual water out of the fabric to prevent water streaks in the paper.
 

The DuoCleaner Express operates in the pressure range of 25 to 64 MPa. A washing station allows the cleaning head to be cleaned automatically in the “park” position while the paper machine is running.
