(used by the aircraft industry) - The same material used in the F-22 Raptor fighter jet. Our Raptor Generation 4 blades can last 75 years in the sun!Made to withstand extreme heat and sub-zero temps, our blades are designed for high speed, high efficiency, affordability and durability. They are rated to withstand 125 mph winds and are designed to operate real PMA's (permanent magnet alternators) at high speed in low winds to create the maximum power a PMA can put out. Our precision, aerodynamically tapered blades feature a 5.5 mph start up speed. Our superior Raptor Generation 4 blades can be used on AIR-X or other wind turbines to increase low wind start-up, power production, and improve safety from plastic/PVC blades.
We've tested many blades on the market and have concluded that our Raptor Generation 4 blades are hands down the best for durability, performance, aesthetics, and overall value. Raptor Generation 4 Blade Specifications.
