The Raptor G4 wind turbine blades are made from revolutionary carbon fiber composites (used by the aircraft industry) - The same material used in the F-22 Raptor fighter jet.
- Designed for high speed, high efficiency, affordability and durability.
- 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.
