Airfusion Climate II DC Ceiling Fan

My office is in the roof space of my home and is facing south so it gets very hot from March to October sometimes unbearably so. Opening the window alone is not enough to cool it down even with other windows open in the house creating a through draft. The fan accelerates the draft drawing in the cooler air to great effect. During the heatwaves I simply leave it on at low speed so that my office is lovely and cool not just in the morning but for the rest of the day. Even better it is far cheaper than air conditioning since there is no dry air. Apart from a short period around 3-4 pm when the whole house has warmed up but the outside air temperature has not fallen much, it is just as cool as air conditioning.
