Applications
Industrial Exhaust Fans
High-capacity exhaust and ventilation fans for factories, workshops, and heavy industrial environments with corrosive fumes.
Marine Propeller Blades
Saltwater-resistant FRP propellers and thruster blades for marine vessels, workboats, and offshore platforms.
HVAC Fan Impellers
Lightweight, corrosion-free centrifugal fan impellers for commercial and residential HVAC systems.
Chemical Processing Fans
Acid and alkali-resistant fan blades for chemical plants, wastewater treatment, and corrosive gas extraction.
Ventilation Systems
Large-diameter ventilation fan blades for tunnels, mines, agriculture, and large-scale commercial ventilation.
Cooling Tower Fans
Large FRP cooling tower fans for power plants, refineries, and industrial process cooling applications.
Material Advantages of FRP Fan Blades
Superior Corrosion Resistance
FRP is inherently immune to rust, corrosion from acids, alkalis, saltwater, and most industrial chemicals. Outlasts metal blades in harsh environments by 3-5x.
40-60% Lighter Than Metal
Significantly reduced blade mass means lower bearing loads, reduced motor power consumption, and longer equipment life.
High-Strength Performance
Custom fiber orientation engineering delivers superior tensile and flexural strength. Blades maintain structural integrity at high RPMs.
Low Inertia, High Efficiency
Lower rotating mass enables faster start-stop cycles, improving system responsiveness and energy efficiency in variable-speed applications.
Lower Total Cost of Ownership
Longer service life, reduced maintenance, no corrosion replacement costs, and lower energy bills make FRP blades more economical long-term.
Non-Magnetic & Non-Sparking
FRP is naturally non-magnetic and non-sparking — ideal for sensitive environments, MRI facilities, and explosive atmosphere (ATEX) zones.
Manufacturing Process
Design & CFD Review
Analyze airflow requirements, pressure, RPM, and operating environment. Optimize blade geometry using CFD-assisted design for maximum efficiency.
Mold Making
Create precision molds matched to your blade geometry — single-piece or multi-segment molds for large blades.
Layup & Curing
Vacuum infusion or hand layup with optimized fiber architecture. Resin system selected for chemical and temperature environment.
Trimming & Balancing
CNC trimming to exact profile, hub bore machining, and dynamic balancing to ISO G2.5 standard (or better).
QC & Delivery
Dimensional inspection, balance verification, tensile testing on samples, secure packaging, global shipping.

Frequently Asked Questions
Can you manufacture custom fan blades from our drawings?
Yes. We can manufacture custom FRP fan blades from your technical drawings, CAD models, or even an existing sample. Send us your dimensional requirements, airflow specs, RPM, and operating environment, and our engineering team will design an optimized fan blade solution for you.
What materials are used for FRP fan blades?
We use high-quality E-glass fiberglass or S-2 glass fibers with premium resin systems. Options include: isophthalic polyester resin (standard), vinyl ester resin (corrosion-resistant), epoxy resin (high-performance), and fire-retardant resins for hazardous environments. Core materials can include foam or balsa wood for large blades.
What is the maximum size for FRP fan blades?
We can manufacture fan blades up to 5 meters in diameter. Standard production range covers 200mm to 5,000mm diameter blades. For very large fans, we use segmented blade construction for easier transport and assembly while maintaining structural integrity.
Do you offer OEM services for fan manufacturers?
Yes, we are an experienced OEM partner for industrial fan manufacturers, HVAC companies, and marine equipment producers. We offer branded fan blades with custom colors, logos, and packaging. Our production capacity supports both small prototype runs and large-scale OEM orders with consistent quality.
What is the typical lead time?
Prototype fan blades: 7-15 days. Production orders: 20-30 days depending on quantity and complexity. Rush prototyping is available at additional cost. We also maintain standard blade inventories for common sizes to support urgent replacement needs.
