An apparatus for preventing a build up of snow or dust. The apparatus includes a plurality of air nozzles positioned around a periphery of a target area to be kept clear of snow or dust. Each of the nozzles directs a stream of air away from the target area. A deflector is positioned around a periphery of the target area. The deflector deflects the stream of air from each nozzle across the target area, wherein an air curtain is formed preventing snow or dust from landing on the target area.
