1. POWERFUL: Blower fan is small but powerful, it can produce a powerful 110CFM airflow at 6000RPM ( maximum ) 45dBA ( maximum ) for applications with restricted airflow, ideal for cooling electronic equipment and components in tight spaces.
2. BRUSHLESS MOTOR: Mini blower fan includes DC brushless motor with P.B.T. housing and dual ball bearings, rated at 50,000 hours, allowing the fan to be placed flat or upright.
3. ADJUSTABLE SPEED: Small blower fan has a speed controller with a power switch to set the fan speed to the optimal noise and airflow level for various applications and noise environments.
4. PLUG AND PLAY: Blower fan is easy to install, after installing the screw set simply plug it into a wall outlet to start the blower. Power adapter increases the maximum fan speed and enables the fan to be powered through an AC power outlet.
5. VOLTAGE RANGE: 3.5V starting voltage; working voltage range 7 to 13.5V, the blower fan can work when it exceeds 13.5V, but it will affect the life of the fan.
