Apart from the conventional functions, this model of the A90 C also features the new vacuum docking function. It enables the automated ventilation during cartridge changes and thus an absolutely bubble-free docking process between the material cartridge and the dispensing system. With it, the material waste per cartridge change can be reduced by up to 90 percent. Users not only benefit from absolute process reliability but also from considerable cost savings - especially in the case of expensive dispensing media.
For the vacuum docking process, Scheugenpflug specifically designed an innovative docking sleeve with filter insert. The sleeve is manually put on the filled material cartridge, which is inserted into the cartridge mount of the A90 CV afterwards. The ejector of the cartridge expulsion unit then evacuates the air within the docking sleeve. The integrated filter prevents the introduction of dispensing material into the ejector line.
