A high-airflow exhaust fan designed to cool and ventilate greenhouses, garages, attics, workshops, and sheds. The system can automatically eliminate heat, moisture, odor, and dust from enclosures, rooms and buildings. Features an inline speed controller utilizing PWM-technology. Innovative EC-motor with PWM-control maximizes airflow while reducing energy consumption and noise levels. Heavy-duty build features aluminum blades, steel wire guards, and steel shutters. Includes everything needed to mount the fan unit and power it through an outlet.
The inline speed controller enables you to set the shutter fan’s speed to optimal noise and airflow levels for various environments. This shutter fan features an EC-motor that is precisely controlled using PWM (Pulse Width Modulation). This technology enables the fan's motor to be able to run smoothly at extremely low RPM speeds without generating motor noises and heat as seen on variable voltage controllers. Eight-speed options are available with a power switch, and backup memory.
Features steel shutters that are weather and corrosion resistant, and automatically closes when not in use. The blades and impeller are constructed of lightweight aluminum, weight-balanced to reduce vibrations. Utilizing an innovative EC motor that is controlled electronically using PWM (Pulse Width Modulation), the fans can maximize airflow while reducing noise and power consumption. The fully-enclosed motor is also permanently lubricated and houses dual-ball bearings that are rated at 67,000 hours. The unit is IP-44 rated to be highly resistant to dust and liquids, and performs well even in harsh environments.
