AC Infinity AIRLIFT S14, Shutter Exhaust Ventilation Fan 14", Speed Controller

Description High-Airflow Exhaust Fan: This fan is designed to eliminate heat, moisture, odor, and dust from a variety of environments. Constructed with steel shutters and aluminum blades, this fan gives excellent resistance to dust and liquids, and is ideal for ventilating greenhouses, garages, attics, workshops, and sheds. Eight-Speed Manual Controller: Using Pulse Width Modulation (PWM) technology, the inline speed controller allows you to adjust the fan speed to attain optimal airflow and noise levels according to the environment. Consequently, the fan can operate smoothly at low RPM speeds, without creating excess noise or heat. Energy-Efficient EC-Motor: The EC-motor of the fan, controlled by PWM, enhances the airflow while decreasing energy consumption and noise levels. This motor is fully enclosed, permanently lubricated, and houses dual ball bearings with a life rating of 67,000 hours. Heavy-Duty Construction: This fan features weather and corrosion-resistant steel s
