Dust Smoke Filter Banks | Indoor Air Quality
These filter banks filter the exhaust air from a welding lab where lots of smoke, fumes and related dust ends up going through these smoke filter banks. Specialized filtering systems are commonly used in industrial areas where fumes, smoke, and dust can be hazardous to the health of people working there. These are tied in to special exhaust fans and the buildings DDC system. Whenever someone enters a booth to begin welding in the welding booths they engage the smoke/fume exhaust switch and an exhaust fan energizes to pull any fumes and smoke out of the booth area and through the duct work where it terminates at these filter banks. The DDC monitors the differential pressure across the filters so when the filters are loaded up a signal is sent to an operator to change the filters. Specialized filter systems can be used for dust collection, smoke and fume collection and mitigation, gas vapors, and mist from liquids.
