Designed to project large amounts of air long distances, the High Velocity Drum Fan provides fresh air on loading docks, in warehouses, and down assembly lines, or to dry out after a flood and exhaust fumes. It has an efficient single-speed direct-drove TEAO (Totally Enclosed Air Over) motor with three galvanized aluminum fan blades. It comes with a yoke mount connected to a mounting assembly for installation on a wall or column.
