AC Infinity AIRLIFT S-Series Shutter Exhaust Ventilation Fan with Speed Controller – 16 in

AC Infinity AIRLIFT S-Series shutter exhaust fan with speed control The AIRLIFT S-Series exhausts heat, moisture, odor, and dust out of a room through a weather-sealed shutter. Four sizes cover the range: 631 CFM at 10 inches, 830 at 12, 1513 at 14, and 2560 at 16. A PWM-controlled EC motor pushes that airflow while holding noise and power down. Steel shutters close automatically when the fan stops, sealing out weather and pests. EC-motor shutter fan with 10-speed manual controller The included controller sets up to 10 speed steps, so you dial the airflow and noise to the room. Growers mount it high on a wall or gable to pull hot, humid air out of a greenhouse, shed, or flower room. Aluminum blades and steel wire guards ride on dual-ball bearings rated to 67,000 hours. An IP44 frame keeps dust and liquid out in harsh, humid spaces. Backup memory holds the last speed after a power cut. For automatic climate response, the T-Series adds a temperature and humidity controller.
