  • Seal for oven circulating fan
    Patent number: 6592365
    Abstract: A multiple-piece seal is used for a cure oven circulating fan. The seal may be readily positioned along the length of the shaft to control the small clearance between the rotating seal and the oven such that there is no contact between the seal and the oven, but the flow of heated air from the oven is substantially reduced and redirected away from the bearings of the circulating fan. The multiple-piece design permits seal replacement without having to disassemble the shaft, so that the seal may be replaced entirely from the outside of the oven, saving substantial down-time.
