CFP Qualitech in Trois-Rivières, Quebec is a trade school center providing professional educational training in areas like welding. The welding department was producing welding fumes from multiple source capturing points. Because of these welding fumes, they required more filter area, leading to a lower air to cloth ratio and exhausting to the outside of the building. High heating energy costs and the potential for harmful fume exposure were significant issues.
Mr. Dany Dontigny, Mr. Gilles Laurendeau, and Mrs. Sonya Marchand of the engineering firm Dessau Inc., along with Jean-Paul Fournier of Cometal Drummondville, went to CFP Qualitech and addressed their issues with a GS32 and a GS108 Gold Series® industrial dust collector. The GS32 is equipped to handle 23,500 CFM at 11”w.g., while the GS108 offers a performance of 78,000 CFM at 11” w.g. The GS32 includes a 75hp motor fan, and the GS108 features a 200HP remote mount fan.
The units were also equipped with the following components: a special integrated control panel, a drop out box to handle sparks, high-efficiency fire retardant cartridges, safety monitoring filters, a platform, and a ladder. These units have been installed at the school since March of 2008, successfully running with the original cartridges still in place.
