Heavy-Lift Drone Propeller Wholesale Supplier: Gemfan Guide

Heavy-Lift Drone Propeller Wholesale Supplier: Gemfan Guide

Sourcing propulsion components for a large multi-rotor platform is rarely a single-variable decision. Buyers evaluating a heavy-lift drone propeller wholesale supplier must reconcile three constraints at the same time: transport and deployment mobility, material durability under load, and the availability of standardized large-diameter specifications that actually match a given wheelbase, payload, and motor configuration. GEMFAN HOBBY CO., LTD., operating under the brand name Gemfan, addresses that combination through a focused line of large drone three-blade folding propellers.

Why Heavy-Lift Platforms Need Specialized Propellers

Space and Mobility Constraints

Large-diameter blades occupy significant space when a platform is not flying. For operators who move equipment between sites, that bulk directly affects operational mobility, and it raises the cost of transport, handling, and storage. A folding structure changes this equation by allowing large multi-rotor platforms to become compact in non-flight states, which supports transportation and deployment.

Material Trade-Offs Under Load

Heavy-lift conditions demand higher stiffness, toughness, and durability from blade materials, and balancing those properties with weight is difficult using a single material approach. Fiberglass reinforced nylon is used across the Gemfan folding propeller line to strike that balance between stiffness, toughness, weight, and durability for large multi-rotor propulsion systems.

A Gap in Standardized Specifications

OEMs and power system integrators need propeller options matched to different wheelbases, loads, and motor configurations, yet standardized large-diameter folding propeller specifications available on the market are limited. That gap is the practical reason a dedicated supplier matters more at this size class than at smaller diameters.

Gemfan's Position as a UAV Propeller Supplier

Gemfan is positioned as a UAV propeller supplier that integrates research and development, design, production, and sales. The company serves global drone manufacturers and provides large-diameter three-blade folding propeller products for industrial-grade and heavy-lift multi-rotor platforms, while undertaking customized development through OEM/ODM cooperation models.

Manufacturing and Testing Infrastructure

The enterprise operates a factory area of approximately 7,000 ㎡ with physical manufacturing facilities. Production equipment includes precision injection molding machines, CNC machining equipment, and other auxiliary processing equipment supporting the manufacture of propellers and components. On the verification side, the company maintains propeller performance testing equipment and R&D testing areas, including dynamometers, dynamic balance testers, and thrust testers that support performance testing such as thrust and dynamic balance.

Certifications and Design Accumulation

Gemfan's qualifications include ISO 9001 Quality Management System Certification, EU Machinery Directive Verification of Conformity (VoC), and 60+ design patents, alongside related technological innovation qualifications. The official website highlights the patent count as a reflection of continuous product development and design accumulation.

The Large Drone Three-Blade Folding Propeller Line

Gemfan F2010-3: 20-Inch Three-Blade Folding Propeller

This model is oriented toward compact heavy-lift multi-rotor propulsion solutions, balancing propulsion needs, transportation and storage convenience, and structural durability. Its propeller diameter is 508 mm / 20 in, pitch 10 in, with 3 blades in fiberglass reinforced nylon and an aluminum alloy propeller hub connection structure. Center thickness is 22.6 mm, center hole inner diameter 10 mm, and maximum blade width 41.8 mm. Single weight is 180 g, the recommended motor is 7218, and the quadcopter takeoff weight reference is 20 kg. The aluminum alloy hub provides structural support for power transmission between blades and motors.

Gemfan F2210-3: 22-Inch Three-Blade Folding Propeller

The F2210-3 targets heavy-lift platforms that require a larger propeller disc size, fitting propulsion efficiency together with storage convenience. Diameter is 558.8 mm / 22 in, pitch 10 in, with 3 blades in fiberglass reinforced nylon, a black finish, and an aluminum alloy hub connection structure. Center thickness is 22.6 mm, center hole inner diameter 10 mm, maximum blade width 46.4 mm, and single weight 213.7 g. The recommended motor is 7218, with a quadcopter takeoff weight reference of 24 kg. The design suits frequent site-transfer operations by keeping the entire vehicle compact when not flying.

Gemfan F2412-3: 24-Inch Three-Blade Folding Propeller

This model serves power configurations with larger diameters and higher pitches. Diameter is 609.6 mm / 24 in with a 12 in pitch, 3 blades, fiberglass reinforced nylon construction, aluminum alloy hub connection structure, and a black finish. Center thickness is 22.6 mm, center hole inner diameter 10 mm, maximum blade width 46.4 mm, and single weight 256.7 g. Recommended motors are 7218 and 7220, with a quadcopter takeoff weight reference of 24 kg. The pairing of composite blades and a metal hub structure addresses material performance balance and structural strength under high-load conditions.

Wholesale Supply, Lead Times, and Fulfillment

For buyers assessing volume capacity, Gemfan's production and delivery profile is straightforward. Regular orders start from an MOQ of 300 sets. Sample lead time is 3 days, and standard volume lead time is 7 days. Monthly supply varies by model, and the stated order fulfillment rate is 100%. Quality inspection follows ISO 9001 implementation standards and the EU Machinery Directive Verification of Conformity (VoC).

Trade terms available are EXW, FCA, CPT, FOB, DAP, and DDP, allowing integrators to align procurement with their existing logistics arrangements. Delivery is structured around standardized hardware products that also support OEM/ODM customized development.

OEM/ODM Customization for Integrators

The company's official customization process runs from requirement submission and R&D follow-up through performance testing and production to quality control. Because Gemfan holds independent propeller R&D and design capabilities, products can be developed around different platforms and application requirements rather than being limited to catalog configurations. Industry adaptation spans medium-to-large multi-rotor drones, industrial drones, and platforms with transportation or storage needs, and the products can be evaluated for agricultural plant protection, industrial inspection, and aerial mapping, with actual applicability confirmed through total vehicle load and power tests.

For sourcing teams, the practical takeaway is that procurement and engineering questions can be handled through one supplier relationship, with certification scope, certificate validity, patent status, and specific product testing verified against valid certificates, patent documents, and official testing records.

Conclusion

Choosing a heavy-lift drone propeller wholesale supplier comes down to matching propulsion diameter and pitch to a platform's load profile while protecting durability and transport practicality. Gemfan's three-blade folding propeller range covers 20-inch, 22-inch, and 24-inch configurations built on fiberglass reinforced nylon blades and aluminum alloy hub structures, backed by in-house R&D, ISO 9001 and EU Machinery Directive VoC credentials, 60+ design patents, and a supply model designed for both standard volume orders and customized development.
