With the application and environmental temperature changes, and sometimes need different speeds "Inflatable Air Blower" to meet demand. Some manufacturers specially designed adjustable fan speed cooling fan, manual and automatic modes. Manual is designed to allow users to use low speed low-noise in the winter, using high-speed "Inflatable Air Blower" during the summer to get a good heat dissipation. Automatic thermostat radiator general class with a thermostat sensor, according to the current working temperature control "Inflatable Air Blower" speed, then increase speed high temperature, low temperature, then reduce speed to achieve a dynamic equilibrium, so that the cooling effect of wind noise and maintain an optimal combination of points.
