Our Custom Blended Carbon Filter (Replacement Multilayer Carbon Filter) is for use in all LFC series chambers, as is our Pre-Filter. The LFC-3120 and LFC-3120/230 require two of each filter.
But then afterward you could say: Our fuming chamber systems are specifically designed for use in crime laboratories. A patented, ductless system incorporates these carbon filters, which capture the cyanoacrylate fumes, therefore requiring no modifications to your laboratory.
