The Windmachine is designed to create maximum air-flow with minimum noise for Hollywood sound stage use. A rheostat control varies the speed of the fan to produce wind effects from a light zephyr to a stiff breeze. This Moleffect is useful not only for routine wind effects, but also for dispersing snowflakes, creating a localized dusty breeze, etc. Radial vanes columnate air-stream; vanes may be removed for wide dispersion. At high speed the fan may be used to cool or ventilate a set or to clear smoke. The unit sets on the floor or mounts on a stand. Equipped with a tubular steel roll cage for safety, protection and ease of handling.
