  • Patent number: 5480282
    Abstract: A high velocity, weather resistant cooling fan for moving large volumes of air long distances can be disposed in either oscillating or non oscillating modes, either inside or outside. A rigid, generally tubular housing has a suitable guard defined on each end. A propeller mounted within the housing, coaxially disposed adjacent an intake venturi, is directly driven by an electric motor. The fan venturi inlet is formed by a flare defined in its housing at the intake end. A transition zone is defined within the tubular housing where the diameter of the flared end gradually reduces and smoothly merges with the uniform diameter of the housing. The propeller is mounted within the transition zone to stabilize air before discharge. A generally U-shaped yoke, rolled from welded, nested channels, pivotally mounts the fan. A stabilizer tube is preferred for sturdily mounting the yoke to a suitable post.
