A whole house fan system designed to be installed in attics to keep homes cool; it exhausts hot air from indoor spaces while creating passive intake to pull in fresh air. Each attic fan is controlled by a wireless fan remote that can adjust the fan speed in up to 10 levels. This will enable you to conveniently optimize your desired cooling and noise levels from anywhere in your home. The fan uses a PWM-controlled EC motor that allows it to run efficiently and quietly. This kit includes 4-layer ducting, stainless steel duct clamps and grille, and a 2-door shutter that blocks attic air from flowing into your home when the fan is not in use.
