DOX RotoClean/S

Print Paper Cleaning System

Surface cleanliness is very important for subsequent treatment in the printing industry. Dust particles in the Printing Presses interrupt the operation, causing inferior printing quality due to contamination of the blankets. Extensive trials have proven that a web cleaning unit must not only remove loose dirt particles, it must also eliminate statically charged particles which stick to the web surface. We recommend the use of the DOX RotoClean/S to achieve satisfactory results.

Advanced Print Paper Cleaning System

DOX RotoClean/S Description
The cleaning unit is designed for a large-capacity vacuum. The cleaning effect operates evenly and continuously across the full width of the running web.

During operation, the web enters the vacuum section for absorbing all dust particles. An air doctor (blade) and an antistatic high-voltage bar are installed in this section. By passing through the ionization field as developed by the antistatic bar, the web is deionized. The air doctor can be infinitely adjusted to various angles to the web to ensure that all dirt and fine particles are loosened and absorbed.

Through the combination of deionization, doctoring with air and an extensive vacuum, all dust particles are removed. The antistatic bar ensures that after the web leaves the unit it will not attract new dust particles.

The air containing the dust particles is sucked into the dust extraction unit and passes through a cyclone filter. The absolutely clean air is recirculated to the working area. This cyclone filter contains a vibrating device for periodic filter cleaning. The absorbed dust particles are collected in an easily accessible container.

A separate compressor produces the necessary airflow for the cleaning system to guarantee the optimum functioning of the air doctor.
