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 an LCD digital controller, featuring a smart thermostat with triggers, fan speed control, and status alerts. The fan uses a PWM-controlled EC motor that allows it to run efficiently and quietly at a maximum of 48 dBA. 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.
