QuietCool ES-6000 Whole House Fan 120V. 5,576 CFM 2-Speed Ducted Attic Fan

The QuietCool ES-6000 whole house fan moves up to 5,576 CFM through a patented, attic-hung ducted design that keeps motor noise out of the living space, cooling homes and grow rooms up to 2,790 sq ft. This ducted whole house fan runs on a 2-speed ECM motor drawing just 455 W on high and 112 W on low for fast heat exchange without the load of running more AC. QuietCool ES-6000 Whole House Fan Built for Quiet, High-Volume Air Exchange The QuietCool ES-6000 whole house fan pairs a patented self-contained acoustical duct with a barometric R5 damper box that hangs from the attic rafters, neutralizing the vibration and motor hum that make standard electric attic fans hard to run near sleeping areas or occupied grow rooms. On high it moves 5,576 CFM while pulling 455 W, and its low speed drops to 3,417 CFM at just 112 W, giving two clean airflow stages from a single 120 VAC ECM motor. At the recommended 2 CFM per square foot, one unit covers up to 2,790 sq ft of home or grow space. Ducted Whole House Fan That Retrofits Without Framing Installed as a ducted whole house fan, the ES-6000 hangs in the attic on a 9-foot 22-inch duct and drops into a 14 1/4" x 36 1/4" ceiling opening that fits 16" or 24" on-center joists with no framing or joist cutting. Growers typically run it at night with a few windows cracked, pulling cool outside air across the canopy and pushing accumulated heat and humidity out through the attic, then drop to low speed once room temps stabilize. It wires to an 8-hour electronic timer, a double 3-way switch, or Wi-Fi smart controls (sold separately), and the R5 damper doors seal the ceiling against attic air when the fan sits idle. A minimum of 7.44 sq ft of net free attic venting keeps the system exhausting efficiently. Key Features Whisper-quiet ducted design: A patented self-contained duct and R5 damper box hold noise and vibration in the attic, so the fan runs near sleeping areas or occupied grow rooms without complaints. 5,576 CFM two-speed airflow: High and low stages (5,576 / 3,417 CFM) let you push hard heat exchange during peak temps and settle into quiet circulation overnight. Energy-saving ECM motor: Draws 455 W on high and just 112 W on low, moving large air volumes for a fraction of the load a comparable AC pull would add. No-framing retrofit install: Fits 16" or 24" on-center joists with no framing or joist cutting, dropping into a 14 1/4" x 36 1/4" ceiling opening. R5 barometric dampers: Insulated damper doors seal the ceiling against attic air when the fan is off, limiting heat transfer in colder months. 10-year warranty: Backed by a decade of coverage for continuous residential or grow-room duty.
