Camfil APC sales rep Greg Schreier properly sized a six cartridge Farr Gold Series GSB6 with horizontal inlets to accommodate the massive dust loading. The unit was mounted outside and against one wall of the sanding/grinding room, drawing air through a large opening. SFI was quite pleased with the results.
When business and production increased for SFI, they decided to move to a larger facility in October 2005. They called Greg Schreier and asked him to engineer the dust filtration system for the new, expanded production area which consisted of a main room and two smaller “bump out” areas totaling 3,000 square feet. They took their Farr Gold Series GSB6 to the new facility, and Greg recommended an additional, larger Farr Gold Series GSB8 to install as well.

Further, SFI decided to have the clean air from the Farr Gold Series units ducted back 75 feet over and behind the sanders to increase the air exchange rate. Their intent for the Farr Gold Series units was two-fold: collect the dust from the grinding operations immediately in front of the modules, and clear the air of nuisance dust through recirculation. They connected the sanding tools directly to a separate vacuum system.
The installation was a success and the Farr Gold Series units are performing to high expectations, maintaining a clear environment for the 10 to 20 workers that are in the production area at any one time. SFI said they considered competitive dust collection equipment, but were attracted to the Farr Gold Series by the vertical cartridge design, and by their success with their first Farr Gold Series. In fact, neither unit has needed replacement filters (over a year for the GSB8 and nearly two years for the GSB6), and the pressure drop has not yet exceeded 2” s.p. SFI continues to be pleased with the Farr Gold Series’ performance, and they often receive compliments from visitors on how clean their operation is.
