The Bionaire Twin Window Fan is designed for maximum convenience and comfort. This unit is intended to fit double-hung, slider and casement windows, and the fan's two high performance 9" blades are engineered to draw in fresh cool air, exhaust stale indoor air, or exchange for full room circulation. The programmable digital LED thermostat displays the ambient room temperature and is illuminated for visibility in the dark. The remote control is fully featured and offers complete control from up to 15 feet away. More importantly, the Bionaire window fan uses at least 88% less energy than a 5,000-10,000 BTU room air conditioner.
