ABSTRACT:
A toxic fume absorber for a source of toxic or noxious fumes is provided that is particularly adapted for absorbing fumes generated in a chemical reaction involving a change of state. The absorber comprises a manifold or trough adapted for juxtaposition adjacent the source of the toxic fumes. An upwardly facing opening to said manifold is disposed adjacent and below the source of the fumes. A hood extends from the manifold and at least partially encompasses the source of the fumes. A vacuum source is connected to the manifold for drawing fumes down from the source of the fumes and into the manifold. A modularized filter unit and vacuum source is provided for drawing effluent from the manifold, scrubbing the toxic fumes therefrom and returning the same to a controlled atmosphere.
