35 inch WindGrabber Aluminum Blades (Set of 3)

Our most powerful Residential Wind Turbine Blades!

For generators with very large permanent magnet motors or 500-1000 Watt PMA's, our three aircraft-grade aluminum WindGrabber blades are designed to create high torque and power! When mounted, the swept area (diameter) of these blades is a whopping 80 inches (203 cm)! These blades are designed to put out amps on larger motor/generator units. This rotor can create some serious power (AKA horsepower)!

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. Under no load, the Wind Grabber will hit 200 rpm in about 6 mph wind. Additionally, it will begin spinning in approximately 2.5 mph wind (That's why we call them WindGrabbers!).

Durable and quiet, WindyNation produces high quality professionally-designed wind generator blades that won't let you down. 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. We use ultra-smooth dies to shape these 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!

You will not be disappointed with our blades. We are so confident that we offfer a 90-day warranty!

Please note that these blades are not designed to withstand sustained hurricane force winds. Every wind turbine should have a mechanism in place--such as a furling vane--which protects your generator from wind speeds exceeding 35-40 mph. These blades are designed to withstand extreme wind gusts, not sustained conditions.
  • Three (3) 35-inch Wind Grabber blades. The blades are 6 inches wide at the base and 35 inches long (diameter of swept area is about 80 inches with the hub). Wind Grabber blades are CNC-manufactured with a dimensional tolerance of 0.005 inches. They are perfectly balanced and spin fast and smooth. They are manufactured from aircraft-grade aluminum, making them light-weight, durable and rust-resistant.
  • (optional) A precision-machined, rust-resistant powder coated steel hub. It is 3/16 inches thick and 16 inches in diameter. The center mounting hole is available in 5/8 inch diameter or 17 mm diameter, making it easy to adapt to shafts on popular 500 Watt PMAs. The hub is extremely strong and can handle stress forces that will be applied by the blades spinning in very strong winds. There is no need to worry about this hub bending or cracking in strong winds. Already have a hub? Just select the "No Hub" option below.
  • Mounting hardware: 12 sets of stainless steel locking nuts, bolts and washers.
