QuietCool Energy Saver Whole House Fan QC ES-2250

QuietCool QC ES-2250 energy-saver whole house fan The QuietCool QC ES-2250 pulls up to 2,255 CFM to flush hot, stale air out of a room and pull cooler air in. Cooler air comes in through open windows. An ECM motor draws just 115 watts, about 19.61 CFM per watt. It cools grow rooms and homes up to 1,125 square feet. The 16-by-20-inch grille mounts in the ceiling while the fan sits in the attic. Energy-efficient greenhouse and grow room exhaust fan Growers pair it with smaller inline or oscillating fans for room-by-room zone control across veg, flower, and drying. Whole-space air exchange evens out canopy temperature, clears hot spots from lights, and supports steady VPD. It needs about 3 square feet of net attic venting and fits standard framing. The attic mount keeps noise and bulk away from the plants. Running it instead of the AC cuts electricity cost. A 10-year warranty backs it.
