FRP Roof Axial Flow Fan

Why Choose FT35-11 Molded FRP Axial Fan?

Designed for Harsh Environments. Engineered for Lasting Performance.

True Corrosion Resistance, From Inside Out

Seamless Molded Construction
Unlike traditional hand-laid FRP fans, the FT35-11 is integrally molded in one piece. This eliminates joints, seams, and potential weak points where corrosion starts.
→ Result: Full FRP body, zero metal exposure, ideal for chemical labs, marine, and wastewater plants.
Lifetime Protection
Made of high-grade fiberglass reinforced plastic, it resists acids, alkalis, salts, and solvents.
→ Result: 3–5× longer lifespan than steel fans, with zero maintenance againstrust.

Lightweight Yet Strong

Easy to Install
Weighs 30–50% less than equivalent steel fans. Reduces structural load and installation time/cost.
Robust Structure
Uniform wall thickness and dense molding ensure high strength under heavy wind loads.

Energy Efficient & Cost Saving

Aerodynamically Optimized Blades
Advanced impeller design achieves higher airflow with less power.
→ Typical saving: 5–10% lower energy consumption vs. conventional fans.
Smooth Interior Surface
Molded interior minimizes air turbulence and dust accumulation, maintaining peak efficiency.

Safe & Reliable

Non-Conductive & Spark-Free
Perfect for explosive or humid atmospheres (e.g., paint shops, underground parking).
Isolated Motor Design
Motor is separated from the airstream, protected from corrosive fumes.

Quiet Operation

Low Noise Design
Precision balancing + FRP’s natural damping properties reduce operational noise by 3–8 dB(A).
→ A quieter, more comfortable environment.

Maintenance-Free

No Painting, No Rust, No Worry
The FRP body never corrodes. No periodic repainting or anti-corrosion treatments needed.
Easy to Clean
Smooth surface prevents stubborn buildup; simple wipe-down keeps it like new.

Perfect For:

Chemical & Pharmaceutical Plants
Wastewater Treatment Facilities
Marine & Coastal Installations
Food Processing & Agriculture
Parking Garages & Underground Tunnels
