Vitronics Soltec offers an integrated exhaust stack filter for its XPM series reflow soldering ovens. This option filters flux-laden exhaust gases before they pass into the facility’s exhaust system. It also minimizes release of contaminants into the environment. The filter works in conjunction with the manufacturer’s patented flux management system FFC. Here, flux-laden gases are concentrated and ejected from the oven’s process tunnel through specialoutlets. Then the filter condenses flux particles through mixing with ambient air, prior to the gas passing through the filter. It uses standard filter elements readily available worldwide.
