FUME AND SMOKE EXTRACTION
    SYSTEM

The Hakko FA-430 fume extraction
unit is designed expressly for use at soldering stations, extracting the
contaminated air directly at the source. (Shown above: Loc-Line duct with
rectangular nozzle sold separately. See Accessories for details.)  
Contaminated air is captured from the workplace surrounding the
soldering station by the hood or hoods, and transferred to the FA-430 unit by
rigid ducts, and a special replacement filter notification function notifies the operator when the filter needs to be replaced.

Inside the unit, two filters, comprising
three stages of filtering, remove
  the contaminants from the air. The purified air is then returned to the area
  where the FA-430 is located.  
The pre-filter removes coarse
  particles, such as dust, thus extending the life of the main filter. The
  main  filter provides the greatest amount of surface area within the volume
  of the filter case.  
The standard filters contain an activated carbon element built into the filter. This
  filter is designed to last the life of the main filter.
