Functional description
The product can be combined with different filter units from the DDE 2000 // DDE
3000 series. It is equipped with a three-phase motor which drives a radial fan. The
fan unit is supplied or separated from the required energy via the connection to the
main system.
Due to the negative pressure produced by the fan, air is sucked in through the
corresponding filter unit. Permanent filters located in the filter unit separate the dust
contained in the air which is sucked in. The purified air is guided back into the room
through the outlets on the top of the fan unit.
The product is fitted with a pre-separator / air guide plate. This pre-separator / air
guide plate is installed behind the intake port, which pre-separates coarse particles
and thus prevents these coarse particles being sucked against the filter.
The filter cartridges are manually cleaned with compressed air. Compressed air is
connected to the rotating cleaning device in the filter unit of the product via the
compressed air connector. The filters are freed from dust and regenerated through
this cleaning.
The disposal unit attached below the filter collects the dust that has been cleaned
off. The collection drawer is lowered and pulled out for easier disposal of the
collected material. Depending on the material collected, a disposal carton can be
inserted into the collection draw which is disposed of together with the collected
material.

Monitoring the minimum airflow volume
Extraction elements with various intake port diameters can be operated with the
product. When so doing, you must ensure that
The minimum airflow volume sucked away is not undershot.
-
The minimum airflow volume depends on the diameter of the intake
port of the extraction element and the requisite conveying velocity.
