Brand New Set of 5 35" WindGrabber Aluminum Wind Turbine Blades
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
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.

- Five (5) 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 stainless steel hub.
- It is 0.25 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.
- Mounting hardware: 12 sets of stainless steel locking nuts, bolts and washers.
