Several companies(PACE, Impell) offer flux filtration systems for use within the plant, no venting to the outside required. These systems consist of three filters: a prefilter to filter out the large particles, a HEPA type filter to remove the finer particles and a carbon filter to eliminate the smell. We presently use these fume filtration systems on all of our work benches for hand soldering and have larger units on the reflow/glue cure ovens and two of our wave soldering systems. This eliminated the need to put holes in the roof of the facility(they always leak) and we are well in advance of any EPA requirements about exhaust. Venting inside also reduces the amount of make-up air required to be introduced into the facility, reducing air conditioning costs and the need to humidify the air.
