Corrosion Resistance FRP Industrial Exhaust Fan Blower For Harsh Chemical Environments
Product Details
Corrosion Resistance Industrial Exhaust Fan
,Exhaust Fan for Chemical Environments
GF4-72 Type A Series FRP Centrifugal Fan
The GF4-72 Type A Series FRP Centrifugal Fan is a high-efficiency, low-energy-consumption, eco-friendly fan improved from the classic 4-72 model. Optimized for superior aerodynamic performance, it is widely used in chemical, electroplating, oxidation, power plant, laboratory, circuit board, and environmental protection applications to handle corrosive gases containing acid and alkali components.
A specialized explosion-proof variant, BG4-72, is also available. Fitted with an Explosion-proof ExdI or ExdIIA/B certified motor, it safely handles flammable/volatile gases such as methane, ethane, propane, styrene, VOC vapor, xylene, carbon monoxide, acetic acid, kerosene, gasoline, and ammonia. Its performance and installation dimensions are identical to the standard GF4-72 model.
GF4-72-A Model Features
Material & Structural Properties
· The fan body is constructed from fiberglass reinforced plastic (FRP), offering excellent resistance to corrosion by acids, alkalies, and other chemical agents.
· The impeller and housing design is optimized for superior aerodynamic performance, ensuring high efficiency, low noise, and stable operation.
· The direct-drive design uses a flange-mounted B35 motor, which is simple, reliable, and requires minimal maintenance.
· The fan body is lightweight yet rigid, resistant to aging, and built for long-term continuous operation in harsh environments.
Core Advantages
· Excellent Corrosion Resistance: The FRP construction provides long-term protection against corrosive gases, outlasting standard steel fans.
· High Efficiency & Low Noise: Optimized aerodynamic design delivers high airflow efficiency with low noise output.
· Explosion-Proof Option: The BG4-72 variant is available with certified explosion-proof motors for use with flammable/volatile gases.
· Low Maintenance: The one-piece construction is easy to clean and inspect.
Transport Medium Requirements
· The conveyed gas must not contain any sticky substances.
· The concentration of dust and hard particles must not exceed 150mg/m³.
· Gas temperature ≤60°C, relative humidity ≤100%.

A1: It is designed for ventilation and exhaust of corrosive gases in chemical plants, electroplating workshops, laboratories, and environmental protection facilities.
A2: GF4-72 is an improved version of the F4-72 series with enhanced aerodynamic performance for higher efficiency. It also includes the BG4-72 explosion-proof variant for flammable gases.
A3: It works well with most inorganic acids, alkalis, and salts. For flammable/volatile gases, you must select the BG4-72 explosion-proof model.
A4: The maximum gas temperature is 60°C, and the relative humidity can be up to 100%.
A5: Yes, but the dust and hard particle concentration must not exceed 150mg/m³, and the gas must not contain sticky substances.
A6: Yes, it is designed for continuous operation with low vibration and noise, making it ideal for industrial processes.
A7: The standard model uses a direct-drive three-phase motor. The BG4-72 variant uses an explosion-proof certified motor.
A8: Select based on your required airflow (m³/h) and static pressure (Pa). Our technical team can help you choose the best model based on your specific application.
A9: The BG4-72 is a variant fitted with an ExdI or ExdIIA/B certified explosion-proof motor, allowing it to safely handle flammable and volatile gases.
A10: Each unit includes a detailed installation and operation manual, and we offer full after-sales technical support.
