Adjustable downdraft ventilator

An indoor or outdoor downdraft ventilator moves via an electronic controller through preferably a touch keypad. This provides precise control and an efficient way of removal of gases / fumes off a cook top. The electronically controlled telescoping downdraft creates a nearly infinite and selectable range of heights above a cook top from which to properly collect and draw in, filter, re-circulate, or expel exhaust. The downdraft incorporates a lighting system to illuminate the work surface and sensors to detect temperature, filter change requirements, speed, stop points, power, resistance, voltage, and program med operations.
