How to adjust the air flow shutter
The Trotec air flow shutter regulates the air flow between the exhaust system and the 75-mm exhaust connection on the Speedy 300 and Speedy 400 laser engravers or SP500 laser cutters when using a vacuum table.
Adjusting the air flow shutter is easy. By reducing the air flow on this exhaust connection, the suction at the table is automatically increased, creating higher vacuum or increasing the extraction of fumes from the table, respectively.
This leads to an improved hold of films, paper and other thin materials. In addition, the cutting quality with acrylic or other plastic materials is increased as the resulting fumes are extracted immediately, leading to clear and shiny cutting edges.
