An in-wall vent fan designed to quietly circulate air between multiple rooms to maintain a stable temperature. Powered by an intelligent controller that features temperature, timer, and cycle programming. Its airflow is digitally reversible with a single push of a button and allows for an effortless transition between intake and exhaust functionality. Ensuring greater efficiency, the EC motor with next-level PWM controls smoothly operates at extremely low RPM speeds without generating motor noise. The durable faceplates and inner metal frame shield the motor and its dual ball bearings for long-lasting use.
