QuietCool CL-6000 Whole House Fan for Hydroponics
The QuietCool Classic QC CL-6000 whole house fan uses a patented, self-contained acoustical duct and R5 damper box to move up to 5,665 CFM while keeping operation whisper quiet, just like the best QuietCool attic fans. Mounted in the attic with no framing or joist cutting required, this ducted whole house fan pulls cool outside air through open windows, sweeps it across your home and grow room, and exhausts built-up heat from the attic.
Whisper-Quiet Whole House Ventilation for Grow Rooms
With two-speed operation (5,665 / 4,289 CFM), coverage up to 2,840 sq ft, and a 10-year warranty, it’s a powerful alternative or supplement to AC for hydroponic growers who need fast, efficient air exchanges and whole house ventilation. Barometric, pressurized R5 dampers and an acoustical duct help neutralize vibration so the system can run at night without disturbing light-sensitive plants or sleeping households, provided you have at least 7.56 sq ft of net free attic venting.
Energy-Efficient QuietCool Attic Fan Performance
Pair the QC CL-6000 with an 8-hour electronic timer, HI/LOW/OFF switch, or Wi-Fi smart control (all sold separately) to automate ventilation cycles and stabilize temperatures in indoor gardens, attics, and adjoining living spaces. This QuietCool attic fan-style system delivers serious cooling power while helping reduce reliance on traditional air conditioning.
