There have been many changes in laser cutting technology, including new metal thicknesses and more varieties of metal including mild steel, stainless steel, copper and brass. Today's fiber laser tables generate molten metal, smoke, and gases, which can be breathing hazards for machine operators. Good ventilation is required to prevent inhalation of toxic airborne particles, particularly the tiniest particles that can settle deep into lung tissues.
Dust collectors are most commonly used to capture particles at the source. Dust, fumes and smoke are pulled down through the table and removed through the duct-work where they are filtered through the dust collector. The dust collector’s filter cartridges capture all particles until they can be safely removed.
Laser wattage, type of beam, material being cut, type of assist gas, automated material handling system and table size all play a role in determining collector size and airflow. So be sure to consult a Camfil APC expert to size the correct laser cutter fume extractor to solve your laser dust/fume/smoke problems.
