The FRP centrifugal fan is a corrosion-resistant industrial centrifugal fan manufactured with fiberglass-reinforced plastic (FRP). It is designed for conveying acidic, alkaline, saline and other corrosive gases in industrial ventilation and exhaust systems.
EMS supplies customized FRP Centrifugal Fans for chemical plants, electroplating facilities, wastewater treatment, scrubber systems, industrial waste gas treatment, electronics manufacturing and other applications where corrosion resistance is required.

Engineering Note: These are typical reference ranges rather than fixed specifications for every 4-72 configuration. Actual performance depends on fan size, airflow, pressure, gas temperature, gas composition and total system resistance.
Corrosive gas enters the fan through the inlet and is accelerated by the rotating FRP centrifugal impeller. Centrifugal force increases the gas velocity and pressure while changing the airflow direction. The volute collects and guides the gas toward the discharge duct and downstream treatment equipment.
Typical process:
Corrosive Gas → 4-72 FRP Fan → Scrubber → Gas Treatment → Exhaust Stack
Alternative process:
Production Equipment → FRP Exhaust Fan → Duct → Waste Gas Treatment System
FRP construction provides corrosion resistance for many acidic, alkaline and chemically aggressive gas environments.
The fan is suitable for acid fumes, alkaline gases, chemical process exhaust and other corrosive industrial ventilation applications.
FRP provides a lightweight alternative to conventional metal fan construction while offering strong resistance to many corrosive environments.
Different fan sizes can be selected according to airflow, pressure, duct dimensions and available installation space.
The 4-72 FRP fan can be integrated with scrubbers, absorption towers and industrial waste gas treatment systems.
EMS can customize the fan according to gas composition, concentration, temperature, airflow, pressure, materials, motor power, drive type and installation requirements.

For proper selection of a FRP centrifugal fan, customers should provide:
Required Airflow
Total or Static Pressure
Gas Temperature
Gas Composition
Corrosive Medium
Gas Concentration
Dust or Particulate Content
Duct Size and Length
Scrubber / Treatment Equipment Resistance
Motor Voltage and Frequency
Installation Position
Operating Hours
Important: FRP material selection should not be based only on whether the gas is “acidic” or “alkaline.” Different chemicals, concentrations and temperatures have different compatibility requirements. The final resin and FRP configuration should be selected according to the actual gas composition and operating conditions.
