Create air motion using an air amplifier. The air amplifier pulls in a large volume of surrounding air to produce a high volume, high velocity airflow. It creates an output flow of up to 25 times its consumption rate.
Use a wind machine if you need to produce the sound of wind. One type of wind machine consists of rubbing a fabric-covered drum against a wooden rod when a handle is turned. The result is a swooshing sound; musical compositions often use this wind sound effect.
Make wind effects by using fan machines. The Re-Fan II Turbo has a brushless 1/3 horsepower motor and an adjustable speed control. You can focus the wind beam on a specific area by adjusting the vanes.
Try an industrial fan to create wind effects. If you need it for a one-time event, rent one from an industrial supply store. Some people have used a garden vac to create wind effects. Although it works for a small area, it creates quite a bit of noise.
