These are our most powerful rotors for Residential Wind Turbines! Do not waste your money on blades made of PVC, ABS or plastic. With the first strong winds, those blades will suffer irreversible stress failure. Durable and quiet, these high quality professionally-designed wind generator blades won't let you down.  These are made with ultra-smooth dies to shape the blades, minimizing surface defects. All our blades are field-tested and undergo hundreds of hours of prototyping to ensure that they can withstand winds of at least 70 mph! Under no load, WindGrabbers will hit 200 rpm in about 6-7 mph wind. Additionally, it will begin spinning in approximately 1.5-2 mph wind!

For generators with very large permanent magnet motors or 600-1200 Watt PMA's, our three aircraft-grade aluminum WindGrabber blades are designed for extremely high torque and power! When mounted, the swept area (diameter) of these blades is 80 inches (203 cm). These blades are designed to put out amps on larger motor/generator units. Because a larger rotor inherently spins slower, this blade set should not be used on units that have a "cut in" voltage higher than 250 rpm.
