Separation technology dust collector L-CUT TRGS 560 requirements are met with the optional H13 secondary filter and clean air recirculation back into the room is possible. Metal oxides created during laser processes can be separated safely and space-saving. Effective and hazard-free filtration and separation of combustible dusts from thermal processes. 2The housing is of welded design with a variable dirty air inlet opening. The integrated spark pre-separator pro- tects the filter elements against dam- age that could be caused by coarse, potentially glowing particles. All rel- evant components, i.e. disposal bin, filter elements, motor-impeller sec- tion, solenoid valves, electrical switch and control system are acces- sible for servicing from the front. The cartridges consist of a star- shaped folded filtering material which is molded at the bottom and top into an end plate made of sheet steel. A basket of perforated metal plate or wire mesh is installed in the clean air zone which ensures form stability. Filter housing Filter cartridges The cleaning intervals can be adjust- ed individually for each type of appli- cation by means of an integrated control. The fan’s volume flow almost remains constant. Optionally, the cleaning process can be released either via an electronical differential pressure measuring gauge or an ad- ditional cleaning can be programmed in the offline follow-up. Equipped with high-quality components accord - ing to VDE guidelines. Electrical Switch and Control system The one-way dust collection bins form an air-tight connection to the filter hoppers by means of a clamping device. Waste disposal The built-in, directly driven radial fan operates at very low sound levels. The cleaned air is directed upward through an integrated silencer. Fan The L-CUT series has been specially developed for the collection of dust and fumes caused by thermal pro- cesses such as joining, separating, or surface treatment by laser, plasma or gases, to separate the finest of metal oxide particles. These units are com- pact and have a very low profile. Therefore, they can be installed in tight spaces. The spark pre-separator KSE is already integrated in the hous- ing.

Subject to modification Dirty air flows through the dirty air inlet (10) into the spark pre-separator (11) where larger particles are sepa- rated. The collected dust can be emp- tied during operation by closing the manual slide gate. The separated dust is compressed in the disposal container (8) by means of a dust com- pression nozzle (18). Air is deflected after the spark pre- separator (11) which reduces speed when the air contacts the filter ele- ments (12). The dust particles settle onto the surface of the filter ele- ments, are cleaned off by compressed air pulses and then fall into the two disposal containers.The cleaned air flows through an in- termediate level (5) into the clean air chamber where it is pulled through the fan (6) and then exits through the silencer (13).
