Mechanical processes tend to mainly generate oily mists deriving from the lubrication of utensils (turning\rectification, CNC..) and powders/shavings of various kinds deriving from the dry processing of materials, which need to be sucked up and filtered to clean the work environment and protect the health of operators.
We have numerous solutions to this effect: from panel filters with various efficiency classes, electrostatic and bag/cartridge filters or Hepa filters for the re-emission of air into work environments.
