Whilst some applications require a strong vacuum, others demand powerful suction through the exhaust slots. In order to achieve optimal results, we recommend using the air flow shutter to control the extraction air flow.
How to adjust the air flow shutter
When using a vacuum table, the air flow shutter effectively regulates the exhaust system and the 75mm exhaust connection on the Speedy 300, Speedy 400 and SP500.
By simply adjusting the air flow shutter and reducing the air flow on the exhaust connection, the suction at the table is automatically enhanced. A stronger vacuum allows a firmer hold of films, paper and other thin materials. The cutting quality of acrylic and plastic materials is also significantly increased, as the resulting fumes are instantly extracted. This ultimately provides clear and shiny cutting edges.
Adjusting the air flow shutter
Shutter position: closed
View Shutter position: closed
Effects:
Full suction at the vacuum table
No extraction via the exhaust slots in the processing area
When to use:
Ideal for cutting
Shutter position: partially open
View 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
View Shutter position: open
Effects:
Suction at the table and in the processing area is 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.
