The dust being separated inside the filter is continuously returned into the product stream thus preventing a mixing of different types of dust.
Spot filter delivers the cleaned air where the dust-laden air was removed. In this way, no pressure differentials will occur between the production rooms.
The amount of aspiration air is automatically adjusted by the built-on fan, depending on the extent of leakiness.
The large suction intake involves a very low admission speed, thus minimizing turbulence and dust circulation.
In the event of fire in a machine with built-on spot filter, the filter will not act as a connecting link to other machines.
Spot filters are just as suitable for extension of existing central aspiration plants as they are for building up complete plants, only based on spot filters.
With spot filters, existing plants are easily extended. New machines calling for dust aspirations are equipped with separate spot filters, and thus do not interfere with existing aspiration systems.
