QuietCool Energy Saver Whole House Fan QC ES-3100

QuietCool QC ES-3100 energy-saver whole house fan The QuietCool QC ES-3100 moves 3,103 CFM on just 264 watts, an efficient way to dump heat and humidity without running the AC all day. Its ECM motor delivers about 11.75 CFM per watt. It cools spaces up to 1,550 square feet, from a home to a large grow room. Cooler outdoor air comes in through open windows while hot air exhausts through the attic. Energy-efficient attic fan for greenhouses and grow rooms Growers run it as a central greenhouse fan or pair it with smaller inline fans for zone control across veg, flower, and drying rooms. The 16-by-24-inch grille fits cleanly between standard joists. It needs about 4.1 square feet of net attic venting so hot, stale air leaves fast. Strong, continuous air exchange keeps temperature, humidity, and CO2 steady around the canopy. The attic mount frees up floor space for reservoirs and tables. A 10-year warranty backs it.
