QuietCool Whole House Fan for Hydroponic & Greenhouse Ventilation
The QuietCool Energy Saver QC ES-2250 whole house fan pulls up to 2,255 CFM of air, making it ideal as a high-capacity greenhouse fan or hydroponic ventilation fan for rooms up to 1,125 sq ft. Its 16" x 20" grille mounts cleanly in the ceiling while the fan sits in the attic, drawing hot, stale air out and replacing it with cooler, fresher air to stabilize your grow room climate.
Energy-Efficient Grow Room Exhaust Fan
Powered by an ultra-efficient ECM motor, this energy efficient fan uses just 115 watts (19.61 CFM/W), letting you replace or reduce A/C use and cut electricity bills in your indoor garden. Combine the QC ES-2250 with smaller inline fans or oscillating fans for precise zone control, turning it into a powerful grow room exhaust fan that improves temperature, humidity, and CO₂ exchange throughout your hydroponic setup.
