Kadant Web Systems has launched the air-assisted Airset blade holder, which incorporates integrated cavities for targeted delivery of air that boosts the cleaning action of the doctor blade. Air can be targeted behind the blade for dewatering drilled rolls or ahead of the blade for cleaning grooved rolls or belts.
The natural vacuum found in doctoring applications is amplified with the introduction of air. This in turn allows the Airset blade holder to efficiently remove water from the roll surface. More specifically, the patent-pending shape of the holder creates an entrainment zone suspending the removed water from the surface of the roll for removal by a second doctor blade or pan. In-house testing has shown improvements in vacuum efficiency to be more than 25%, and in some cases up to 50%, compared to installations not using the air-assist feature.
For ease of installation, the Airset blade holder can be mounted to the doctor utilizing Kadant’s patented UniTrak™ blade holder installation and removal tool.
