QuietCool QC CL-3100 Classic whole house fan
The QuietCool QC CL-3100 moves up to 3,190 CFM on high and 1,906 on low through a patented acoustical duct and R5 insulated damper box. That keeps noise and vibration very low while it pulls cool air in and exhausts hot air through the attic. Two speeds draw 320W and 231W, near 9.97 and 8.25 CFM per watt. A 16-by-24-inch grille and 4.1 square feet of attic venting keep the install simple.
Ultra-quiet ducted ventilation for hydroponic rooms
For a grow tent or room inside the home, it flushes heat from lighting through the attic and draws in fresh, cooler air. The ducted design keeps noise down in living areas while moving strong airflow. Cooling the attic as well as the rooms below helps stabilize grow-room temperature. It can cut reliance on air conditioning for a more efficient environment. The grille fits existing structures without major remodeling. A 10-year warranty backs it.
