Ultra-quiet motors keep the noise level extremely low without sacrificing the fans power. Features a digital push button control panel, six available speed settings, time-delay off functions, and a sleek narrow frame. The fan blades are Teflon-coated and seperate grease from the airflow, depositing it into grease cups. The cups are hidden within the machine for a cleaner look, with just the handles accessible to easily dispose of the grease.
