Description
XICHENG’s PP/FRP centrifugal fan is a specialized industrial ventilation equipment designed for corrosive gas exhaust applications. With 15 years of manufacturing experience in FRP anti-corrosion technology, our fiberglass centrifugal fans solve critical air quality and corrosion issues in industrial environments where standard metal fans would fail prematurely.
Constructed from high-quality fiberglass reinforced plastic (FRP) material, these fans feature strong anti-corrosion performance, long service life, and stable operation. They are engineered to handle corrosive gases without containing viscous substances, with dust and hard particles ≤150mg/m³, gas temperature ≤60°C, and relative humidity ≤100%. FRP centrifugal fans are not suitable for high-temperature applications. For complete exhaust gas treatment solutions, you can also check our industrial wet scrubber systems and PP ventilation ductwork.
How Does The FRP Centrifugal Fan Work?
Step 1: Gas Intake & Impeller Rotation
As the motor rotates to drive the fan impeller, the gas between the blades in the impeller also rotates. The negative pressure formed at the inlet draws in the corrosive gas from the connected ductwork under atmospheric pressure.
Step 2: Centrifugal Force Acceleration
The rotating blades throw the gas outward under the action of centrifugal force, increasing the gas flow rate significantly. This kinetic energy is crucial for overcoming system resistance in long duct runs.
Step 3: Pressure Energy Conversion
As the gas moves through the volute casing, the increasing flow converts kinetic energy into static pressure energy. Then as the fluid is pressurized further, the static pressure energy converts back into velocity energy for efficient discharge.
Step 4: Clean Gas Discharge
The pressurized corrosive gas is discharged through the exhaust port at the required pressure and volume. Under the same power, wind pressure and air volume are generally inversely proportional—higher pressure means lower volume and vice versa—allowing optimal motor power efficiency based on ASHRAE standards.

Application Industries & Use Cases
Chemical Manufacturing Plants
Chemical plants produce various corrosive gases from production processes. Our FRP centrifugal fans reliably exhaust acidic and alkaline fumes, protecting workers and equipment from corrosion damage while maintaining compliance with environmental regulations.
Electroplating & Surface Treatment
Electroplating operations generate highly corrosive chrome, acid, and cyanide fumes. Our fiberglass fans handle these aggressive environments without degradation, providing consistent ventilation for tank lines and workstations.
Oxidation Processes
Oxidation facilities require reliable exhaust systems for chemical reaction byproducts. Our FRP centrifugal fans provide stable air flow control, ensuring process safety and emissions compliance in continuous oxidation operations.
Power Plants & Utilities
Power plants need corrosion-resistant ventilation for chemical storage areas, water treatment sections, and battery rooms. Our fans handle the humid, corrosive environments typical of power generation facilities with dependable performance.
Research & Testing Laboratories
Laboratories require precise, reliable exhaust for fume hoods and experimental setups. Our compact FRP centrifugal fans provide quiet, consistent performance, making them ideal for laboratory environments where reliability is critical.
Circuit Board Manufacturing
PCB factories produce corrosive etchant and solvent vapors during production. Our FRP centrifugal fans, paired with our PP air dampers, provide complete ventilation solutions for clean rooms and production areas, protecting sensitive electronics from contamination.
Successful Customer Case
A leading circuit board manufacturer in Guangzhou was facing repeated failures with their steel exhaust fans due to highly corrosive etchant fumes. The company was replacing fans every 12-18 months at $8,500 each, plus $15,000 in downtime costs per incident. They needed a reliable solution for their 25,000 m³/h system with 45°C gas temperature and 90% relative humidity.
After on-site assessment by our engineering team, we installed six custom FRP centrifugal fans with variable frequency drives, integrated with their existing ventilation control system. The solution included vibration monitoring and automated bearing lubrication systems.
After 3 years of continuous operation, the FRP fans show zero signs of corrosion and have required only routine maintenance. The client saved an estimated $225,000 in replacement and downtime costs, and production uptime improved by 8%. The system has become their standard for all new facility expansions.

Frequently Asked Questions
What’s the maximum temperature the FRP centrifugal fan can handle?
Our standard FRP centrifugal fans can handle continuous gas temperatures up to 60°C (140°F) with relative humidity up to 100%. For temperatures exceeding 60°C, we recommend our high-temperature PP or stainless steel fan options. Always ensure the gas does not contain viscous substances, and dust/hard particles are ≤150mg/m³.
How long will an FRP centrifugal fan last compared to a steel fan?
In corrosive environments, FRP centrifugal fans typically last 3-5 times longer than carbon steel fans and 2-3 times longer than stainless steel fans. With proper maintenance, our FRP fans provide 10+ years of reliable service, while steel fans in similar applications often fail within 12-24 months due to corrosion.
Can FRP centrifugal fans be used for flammable gases?
FRP is spark-free by nature, making it suitable for certain flammable gas applications when properly grounded and configured. However, each application requires individual assessment based on gas type, concentration, and operating conditions. We recommend consulting with our engineering team and a certified safety professional for flammable gas applications.
What maintenance do FRP centrifugal fans require?
FRP centrifugal fans require minimal maintenance compared to metal fans. Recommended maintenance includes: monthly visual inspections for damage, quarterly bearing lubrication (if not permanently lubricated), annual vibration testing, and impeller cleaning as needed based on dust accumulation. No painting or corrosion protection treatments are required.
Do you provide custom sizing and configurations?
Yes! We offer complete customization including special impeller designs, variable frequency drives, custom inlet/outlet orientations, noise reduction packages, and monitoring systems.
