Grow1 Belt Driven Greenhouse Fan With Shutter, 24". 3,352 CFM. 24" Fan

The Grow1 24-inch Belt-Driven Greenhouse Fan moves 3,352 CFM of air, giving small and mid-size greenhouses the exhaust capacity they need to shed heat and humidity fast. Running on standard 120-volt power and arriving pre-wired, the fan installs quickly and gets to work without special electrical setup. The belt-driven design keeps operation smooth, while the integrated shutter opens automatically when the fan runs and closes when it stops, sealing out pests, debris, and unconditioned outside air. Pair it with intake vents on the opposite wall for efficient cross-ventilation that keeps temperatures stable and plants growing through the hottest parts of the season.
