In 1988 a food manufacturer in Tennessee contacted Aerodyne about its need for an efficient dust collection system for its food processing system. After looking into the facility's operation, Aerodyne suggested the GPC dust collector in combination with a Rotary R-Valve. The company decided to purchase 3 GPC-48 epoxy coated dust collectors and an 8" epoxy coated Rotary R-Valve. With only the occasional routine maintenance on the rotary valves, the system has been operating smoothly for the facility. It was only until recently that the company called Aerodyne again to have its R-Valve replaced with a newer model. The facility's operators have been very satisfied with the longevity and performance of the Aerodyne products they purchased more than 20 years ago.
