I would not recommend fans with metal blades, they will rust and typically require ceilings over 10 feet because they are not considered safe in residential applications. You are best off with fans that have special UV protective ABS plastic blades or thicker solid wood blades that are rated for outdoor wet or damp locations. Wet rated fans have the highest tolerance for abuse from the elements and are the best choice, but a covered porch like yours can use a damp rated or wet rated fan. Also, in outdoor locations it is critical to consider the amount of airflow that the fan produces because open outdoor locations do not allow the air to escape on the sides and the breeze you feel from a fan is a lot less than what you feel in an enclosed area indoors. So you need more powerful fans than those listed above. The Donaire fan recommended below has a wind speed factor of about 3.8 MPH, which is over 50% more breeze than the Westinghouse fan above. The ultimate outdoor fan is made of marine grade 316 stainless steel and has ABS blades. It is the Donaire by Matthews Fan Company and is available in brushed nickel or bronze stainless steel. Here are some pictures of the fan taken from the product detail pages using the Room Settings Viewer at Hansen Wholesale. This feature allows you to add your own room setting so you can see how any fan on the website looks in your own setting, so you may want to give that a try.

Hi! What should I look for when buying outdoor fans that actually blow air? The space is a covered terrace about 10 feet high and I need to buy 3 outdoor fans for the space. What brands should I look for that really work? I live in Florida, so a good outdoor fan is a MUST.

If you use a suitably large overlapping hood with a 10-inch duct, then the Broan, Wolf, and Abbaka down-roof style, ca. 1500 CFM, designs will likely do. Any upblast commercial blower will also work, if properly scaled for the system. Do you care what it looks like?

Your description of the old fan motor wiring is lacking: besides the capacitor wires, an electrical motor needs a power supply and return (hot & neutral if 120V, or hot & hot if 240v) but you only call out a single hot wire (to the relay). Where's the other power line connecting?
