Spot Filters
Mode of Operation
The Simatek spot filter is a miniature bag filter designed to suppress dust emission from machines and silos operating with dusty products.
The Simatek spot filter removes a minor quantity of air from the more or less closed working machine. In this way, a slightly negative pressure is created which prevents dust particles from escaping through leaks or openings.
The built-on fan sucks air through the filter section mounted direct on the machine.
The dust is separated on the outside of the filter bags, and drops into the product stream when the filter bags are automatically pulse-jet cleaned.

Advantages
The Simatek spot filter is an extremely practical alternative to conventional central aspiration,
and offers a number of advantages:
- The dust being separated inside the filter is continuously returned into the product stream, thus preventing a mixing of different types of dust.
- The Simatek 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.
- The Simatek 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 Simatek spot filters, existing plants are easily extended. New machines calling for dust aspiration are equipped with separate spot filters, and thus do not interfere with existing aspiration systems.
Design
The Simatek spot filter is characterized by a simple and functional design.
The low and slender design allows a very easy installation on conveyors and bucket elevators.
The filter bags are automatically pulse-jet cleaned, and the change of filter bags is easily accomplished through the large inspection door.
The Simatek spot filter is also available without a built-on fan, for connection to a large central fan.
