3.2 Functional description
The fan unit can be combined with different filter units from the DDE 5500 // DDE
8500 series. It is equipped with a three-phase motor which drives a radial fan. The
fan unit is supplied with or disconnected from the required power via the connection
to the LISSMAC 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
from the air that is sucked in. The purified air is fed back into the room through the
outlet element on the top of the fan unit.
An automatic post-cleaning function (Jet-pulse) is integrated in the product. The
filters are freed from dust and regenerated as a result of this cleaning. The cleaning
process starts automatically, after a waiting period, if the device is switched off via
the external start/stop (automatic mode) or the STOP button (manual operation). Jet-
pulse cleaning cleans the filter cartridges with compressed air fed into the product.
The Jet-pulse cleaning system can be activated manually by pressing the
button.
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.
