Specs:
Whereas belt-driven fans use up power from the engine to turn, electric fans do not, thus removing any unnecessary load and increasing both fuel economy and horsepower. In addition, you do not have to worry about an electric fan's slowing down at low RPM, as many belt-driven fans do, so you are guaranteed sufficient airflow regardless of the vehicle speed.
Before purchasing an electric fan, be sure to determine the CFM (cubic feet per minute) requirements for your engine. And remember, engines that have been modified or vehicles often used for towing may require additional CFM. There is no limit to the number of fans you can install, as long they all fit appropriately and are mounted on the same side of your radiator so that they do not cancel each other out.
Two types of turn-on sources are available for this fan. The Derale Lighted On/Off Switch for Electric Fans (D16740) - allows for manual control of your fan so that you can choose when to turn it on and off. Thermostatic controls, on the other hand, send a signal to the fan, directing it to shut off when fluid temperatures reach an appropriate level, thus saving power. Once the temperature climbs again and additional cooling is needed, the fan is automatically turned back on. Thermostat switches can be single-stage with pre-set temperatures - D16735, D16738, D16739, D16720 and D16721 - or adjustable - D16778 and D16779.

Today we're going to be taking a look at the Derale 12 inch tornado electric fan with the standard mountint kit. This 12 inch reversible tornado fan will improve your gas mileage and boost overall performance by maintaining proper air flow to your vehicle's radiator. It can be mounted on either side of the radiator as a pusher or a puller with no loss of air flow. It comes from the factory all set up as a puller application. If you want to change it to a pusher application all you need to do is remove the bolt right here, pull the fan off, flip it over, reinstall it on your motor shaft and it's ready to go. You can see it has a nice ultra low profile design for tight applications.
It does use an ultra quiet patented skewer blade design. You can see it has 8 skewered blades on it, very quiet. Now this part includes everything shown here, the fan assembly, the nylon fan mounting kid, and a nice set of detailed instructions that'll tell you how to install this onto your vehicle. a few specs on this, the maximum cubic feet per minute this fan moves is 880. Power draw is 8.8 amps. Just to give you a few dimensions, we're going to do the overall width from edge to edge right here.
It's going to be right at 12 and 3/8ths inches. The height from the very bottom to the very top is going to be 11 and 13/16 inches tall, and the depth from the front to the very back on this is going to be right at 2 and 1/2 inches deep. The fan itself is a 12 inch diameter fan, and the depth of just the fan is 1 and a 1/4 inches deep. That should do it for the review on the 12 inch tornado electric fan with the standard mounting kit.

12-3/8" Wide x 11-13/16" tall x 2-1/2" deep, efficient, reliable tornado fan improves gas mileage and boosts overall performance by maintaining proper airflow to your vehicle's radiator. Includes plastic rods and pads for mounting.Installed just as advertised. Installed it using the single stage relay/thermostat (#16735). Car is a classic (1965), so plenty of room to work, took about 3 hours. Hardest part was deciding how to run/hide the wiring for a clean look. I broke one of the install pads, but extras can be obtained (#13001), about 6$ or so. Came on/ went off just as expected. Good product! Barry.
