A ventilator having a housing with first and second openings is mounted on structure of a vehicle and communicates directly with the vehicle cabin to move air between the vehicle cabin ad the outside environment. The ventilator may be nonportably secured onto the vehicle structure on the windows, panels or the roof and provides a sleek low profile unit having a powered impeller to positively move air between the external environment and the vehicle cabin which impeller may be powered by a self-contained power supply connected with a charging source such as a photovoltaic panel and/or the vehicle's own electrical system. The ventilator may also be portably mounted on a ventilator insert placed within a partially rolled down window or a sunroof to temporarily utilize the circulating effects of the ventilator.
