Advanced Print Paper Cleaning System

DOX RotoClean/S Description
The cleaning unit is designed for 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 angels towards the web to ensure that all dirt and fine particles will be loosened and absorbed.

Through the combination of deionization, doctoring with air and an extensive vacuum, all dust particles will be 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 blowing air special for the cleaning system to guarantee the optimal function of the air doctor.
