Separation technology dust collector L-CUT

Effective and hazard-free filtration and separation of combustible dusts from thermal processes.

Metal oxides created during laser processes can be separated safely and space-saving.

TRGS 560 requirements are met with the optional H13 secondary filter and clean air recirculation back into the room is possible.

Compact and efficient

• Applications:
  • All metals and non-metals
  • Joining: soldering, welding
  • Separation: cutting, milling, grinding
  • Surface Treatment: hardening, engraving, laminating
• The L-CUT series has been specially developed for collecting dust and fumes caused by thermal processes such as joining, separating, or surface treatment by laser, plasma, or gases, to separate the finest of metal oxide particles. These units are compact and have a very low profile. Therefore, they can be installed in tight spaces. The spark pre-separator KSE is already integrated into the housing.
• Filter housing: The housing is of welded design with a variable dirty air inlet opening. The spark pre-separator protects the filter elements against damage that could be caused by coarse, potentially glowing particles. All relevant components, i.e., disposal bin, filter elements, motor-impeller section, solenoid valves, electrical switch, and control system are accessible for servicing from the front.
• Filter cartridges: The cartridges consist of a star-shaped folded filtering material 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.
• Electrical Switch and Control system: The cleaning intervals can be adjusted individually for each type of application by means of an integrated control. The fan’s volume flow almost remains constant. Optionally, the cleaning process can be released either via an electronic differential pressure measuring gauge or an additional cleaning can be programmed in the offline follow-up. Equipped with high-quality components according to VDE guidelines.
• Waste disposal: The one-way dust collection bins form an air-tight connection to the filter hoppers by means of a clamping device.
• Fan: The built-in, directly driven radial fan operates at very low sound levels. The cleaned air is directed upward through an integrated silencer.

Dirty air flows through the dirty air inlet into the spark pre-separator where larger particles are separated. The collected dust can be emptied during operation by closing the manual slide gate. The separated dust is compressed in the disposal container by means of a dust compression nozzle. Air is deflected after the spark pre-separator which reduces speed when the air contacts the filter elements. The dust particles settle onto the surface of the filter elements, are cleaned off by compressed air pulses, and then fall into the two disposal containers.
