Operating principle
Chips and dust are extracted from the individual production machines via three fan groups. These are separated in the filter, transferred via rotary valves to a high-pressure conveying system (HP system) and conveyed to a silo. The air cleaned in the filter is returned to the production hall via a closely branched pipe system, thereby increasing energy efficiency. The high negative pressures at the upstream production machines made hydraulic balancing complex and the use of stronger fans necessary.
