The Hunter Original® fan design dates back to the turn of the 20th century and to this day, delivers superior performance that lasts for years. The heavy cast-iron body not only helps minimize fan wobble, but also helps to draw heat away from the electrical parts of the motor. The motor is also larger than any other ceiling fan, making it the most powerful motor available. This allows the blades to be pitched at a 15 degree angle, which produces greater air movement with less noise. And with the oil-bath lubrication system, all the major moving parts of the motor are well protected to prolong the life of the motor. Added up, these unique design elements produce a high-quality fan backed by a limited lifetime warranty.
