Six-Place Digestion System Fume Removal Options
3. Acid Fume Piping Exhaust System. Located on the left side of the unit,
this exhaust piping removes excess Sulfuric Acid fumes from the
digestion flasks. Attention - The Exhaust Piping must be connected to a
remote blower to remove acid fumes. The unit does NOT have an
integral blower. The remote blower draws the Sulfuric Acid fumes
through the CPVC digestion manifold and exhaust piping provided and
pulls the fumes under negative pressure out through a duct work system
connected to the remote blower and ultimately the building’s exterior.
The 6” exhaust stack of the blower must be connected to a Leak Tight –
PVC duck work system that vents 10’ above the building roof.
