Adjusting the air flow shutter and achieving optimum suction
Depending on the application being processed, the amount of suction that will be required will vary on a case-by-case basis. The air flow shutter will assist you with controlling the extraction air flow, to achieve optimal results with every job.
How to adjust the air flow shutter
The Trotec air flow shutter regulates the air flow between the exhaust system and the exhaust connection on the Speedy 300, Speedy 360, Speedy 400 or SP500 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.

Shutter position: closed
Effects: Full suction at the vacuum table and no extraction via the exhaust slots in the processing area
When to use : Ideal for cutting

Shutter position: partially open
Effects: When the air flow shutter opening is narrow, more pressure will act at the vacuum table, and less fume will be removed in the processing area.
When to use: Ideal for combining engraving and cutting with low dust generation

Shutter position: open
Effects: Suction at the table and in the processing area are normal, as if no air flow shutter were installed
When to use: Ideal in case of strong dust development, e.g. when engraving stamp rubber
