Product Overview
Our anti-corrosion PP/FRP centrifugal fan is a specialized ventilation solution engineered to transport corrosive industrial exhaust gases, solving the common problem of rapid equipment corrosion and failure that troubles traditional metal fans in harsh chemical environments. At XiCheng EP, with over 15 years of experience in industrial air pollution control solutions, we have optimized this fan to deliver reliable performance in acidic and alkaline gas environments, supporting enterprises across multiple industries to meet strict environmental emission standards set by the EPA. Constructed from a combination of high-grade polypropylene (PP) and fiberglass reinforced plastic (FRP), this fan delivers both the lightweight flexibility of PP and the high strength of FRP, ensuring stable operation while handling corrosive gases with temperatures up to 60°C.
How Does The Anti-corrosion PP/FRP Centrifugal Fan Work?
This centrifugal fan uses a high-efficiency impeller to generate centrifugal force, drawing corrosive gas into the fan housing and pushing it out through the discharge outlet, achieving efficient gas transportation through 4 standardized working steps:
Step 1: Gas Intake
The corrosive exhaust gas is first drawn into the fan through the axial inlet. The streamlined inlet design reduces air flow resistance, ensuring smooth gas entry without turbulence, which minimizes energy loss during the process.
Step 2: Impeller Acceleration
As the gas enters the impeller, the rotating FRP/PP blades accelerate the gas flow, converting the motor’s rotational energy into kinetic energy of the gas, generating the pressure difference needed to move the corrosive gas through the ventilation system.
Step 3: Energy Conversion
The accelerated gas flows into the volute housing, where the expanding cross-section of the housing converts the gas’s kinetic energy into static pressure, ensuring the gas can be transported over long distances or through scrubber systems with stable pressure.
Step 4: Corrosive Gas Discharge
Finally, the pressurized corrosive gas is discharged through the fan’s outlet, smoothly entering the follow-up exhaust gas treatment system, ensuring the entire process is leak-free and corrosion-free, protecting the downstream equipment as well.

Application Industries & Use Cases
Our anti-corrosion PP/FRP centrifugal fan is widely applied in industries that generate corrosive exhaust gas, providing reliable ventilation and fume extraction solutions:
Chemical Manufacturing
In chemical production workshops, this fan effectively transports corrosive reaction waste gases, safely delivering the gas to the exhaust treatment system, protecting workers from exposure to harmful fumes and preventing corrosion to standard ventilation equipment.
Electroplating & Metal Finishing
For electroplating and pickling workshops, the fan extracts acid mist generated during the metal processing process, meeting strict workplace air quality standards regulated by OSHA, while preventing acid gas corrosion to the ventilation system.
Pharmaceutical Production
Pharmaceutical factories often produce corrosive solvent fumes during drug synthesis. Our fan safely transports these fumes to the treatment system, helping pharmaceutical enterprises meet GMP and environmental compliance requirements.
Printing & Coating Industry
In printing and coating processes, the fan handles the corrosive organic solvent gases, ensuring efficient ventilation of the workshop, improving air quality while protecting the ventilation system from corrosion damage.
Wastewater Treatment Plants
Wastewater treatment stations produce corrosive odorous gases during aeration and sludge treatment. This fan extracts these odorous and corrosive gases, delivering them to the deodorization system, eliminating odor pollution for surrounding communities.
Laboratories & Research Institutes
For chemical laboratories that handle various corrosive experimental gases, the compact anti-corrosion fan provides safe fume extraction, protecting researchers from exposure to harmful gases and ensuring lab safety compliance.
Successful Customer Case
A large electroplating factory in Guangdong, China, was facing a serious equipment replacement problem. Their original carbon steel centrifugal fans suffered severe corrosion after only 8 months of operation, leading to gas leakage and unstable exhaust gas transport, which caused their downstream scrubber system to fail to meet emission standards. They turned to XiCheng EP for a solution. We provided them with 6 customized 10000 m³/h anti-corrosion PP/FRP centrifugal fans, tailored to their acid gas composition. After installation, the fans ran stably, delivering stable air flow for the scrubber system, and the exhaust gas fully met the local industrial emission compliance standards. Up to now, the equipment has been running stably for 4 years without any corrosion or leakage problems. The client reported that their annual fan replacement and maintenance cost has been reduced by 70% compared to before, and they no longer need to worry about ventilation system failures.

, long service life, and stable operation.
Generally, FRP centrifugal fans can be used on occasions with corrosive gas to discharge corrosive gas. The gas conveyed cannot contain viscous substances, dust, and hard particles less than or equal to 150mg/m3, gas temperature less than or equal to 60 degrees, and relative humidity less than or equal to 100%. Fiberglass centrifugal fans are not suitable for high-temperature places.
Working principle
As the name suggests, the FRP centrifugal fan is a centrifugal fan made of FRP anti-corrosion material. The working principle is that when the motor rotates to drive the fan impeller to turn, the gas between the blades in the impeller also rotates, and is thrown out under the action of centrifugal force. Gas, the gas flow rate increases, so that the gas in the flow converts kinetic energy into static pressure energy, and then as the fluid is pressurized, the static pressure energy is converted into velocity energy, and the gas is discharged through the exhaust port, and it is formed in the middle of the impeller. In order to achieve a certain negative pressure, because the inlet is negative, the outside air is immediately filled under the action of atmospheric pressure, and the gas is continuously discharged and filled under the action of the continuous rotation of the impeller, so as to achieve the purpose of continuous air blowing. Under the same power, wind pressure and air volume are generally inversely proportional. Under the same power, if the wind pressure is high, the air volume will be relatively low, and the wind pressure will be lower if the air volume is large so that the power efficiency of the motor can be fully utilized.
Use
It is widely used in chemical, electroplating, oxidation, power plants, laboratories, circuit boards, environmental protection equipment, and other occasions containing corrosive gases.
