VORTEX Series Fixed-Wing Electric Propellers
Featuring a complete range of models, the VORTEX series adopts an all-new exterior design combined with an innovative aerodynamic airfoil profile. Manufactured from imported nylon material, each propeller undergoes strict dynamic balance control to ensure stable and efficient performance.
Patented Structural Design
Certified patented design, representing advanced propeller technology approved by the National Intellectual Property Administration.
Frosted leading-edge surface treatment improves efficiency at high RPM while effectively reducing the risk of aerodynamic stall.
Refined anti-slip hub texture enhances grip and prevents loosening during operation.
Precision Engineering & Advanced Airfoil Optimization
Developed using full-scale CFD simulation software to accurately replicate real electric propulsion operating conditions, significantly improving thrust efficiency and structural strength.
Micron-Level Blade Tip Design
Ultra-thin blade tips reduce noise, minimize vortex loss, and deliver higher energy efficiency with smoother airflow.
Streamlined Aerodynamics
Smooth blade geometry precisely conforms to aerodynamic principles, ensuring stable airflow and responsive power output.
Strict Dynamic Balancing – Quality in Every Propeller
Each propeller is individually precision-tested under strict factory quality control, delivering reliable performance and superior flight confidence.
Imported Nylon – Strength and Durability
High flexural modulus combined with enhanced material toughness, manufactured with high-precision molds, ensures long-lasting durability and safe operation throughout every flight.
All-Scenario Performance
Designed to withstand harsh environments including wind, sand, and heavy rain, unlocking reliable performance in diverse flight conditions.
Select the appropriate propeller size according to the motor and aircraft manufacturer’s recommendations.
Check propeller balance before use and ensure the propeller nut is securely tightened.
Always protect yourself during operation, especially hands and eyes.
Strongly recommend starting the propeller only in a safe, open area.
Never use damaged propellers, even if surface damage appears minor.
Users assume all risks and liabilities resulting from improper operation or misuse. Gemfan is not responsible for losses or injuries caused by incorrect usage rather than product defects prior to use.
