An ion wind fan can have a collector electrode that mitigates the risk of sparking. In one embodiment, an ion wind can include a wire emitter electrode held in tension in a first direction, and a collector electrode having an elongated opening having an upstream edge and a downstream edge, the elongated opening being elongated in the first direction and positioned downstream of the wire emitter electrode so that the wire emitter electrode is substantially centered along the length of the elongated opening. The downstream edge of the elongated opening includes a chamfered portion.
