El transporte neumático es un fenómeno natural que podemos observarlo en la playa cuando el viento desplaza la arena. Si el viento sopla con fuerza, la capa de arena puesta en movimiento es más espesa. También se observa la aglomeración de las arenas, formando las dunas que resisten los esfuerzos del viento y sólo una ligera capa superficial es movida. Si los productos a transportar son muy finos, permanecen en suspensión, retenidos por el aire; este caso se produce cuando la velocidad de caída es muy lenta ( 0,1 mm/s). Pero si lanzamos un puñado de polvo, parte quedará durante largo tiempo en suspensión, mientras que el resto caerá a tierra.
