18" Shutter Exhaust Fan, Remote 9-Speed 56W EC Motor, 2300 CFM Energy-Efficient Wall Mount Ventilation Fan, Workshop, Warehouse, Barn, Greenhouse, Plug&Play 8-Hr Timer, 3-Year Protection

**18 Inches, 56 Watts** The wide 18-inch wheel is powered by a 56W EC motor that moves large volumes of air while consuming roughly half the electricity of comparable AC fans at maximum speed. Cooler operation extends the motor's serviceable lifespan. **Remote Speeds from Ground Level** For buildings with high ceilings, the wireless remote operates from the floor to adjust all 9 speedsfrom a gentle hum to maximum outputand a 1-8H timer keeps livestock barns and greenhouses on schedule without requiring anyone to climb. **2300 CFM, Held Firm** Sustaining 1600 RPM, the unit provides a full 2300 CFM to clear heat and ammonia odors from distribution halls and stable yardsspaces that overwhelm lesser fans.

**58dB Under Full Load** Noise remains at 58dB even when the fan is operating at peak output, thanks to streamlined blade design. Cows and chickens stay more relaxed, and workers preserve their hearing. **Sealed Against the Weather** The gravity louvers open as air flows and close when at rest, blocking rain and chilly backdrafts while the interior remains insulated throughout winter
