Product Overview
Chemical Industry Fans are designed for demanding gas handling, process ventilation, exhaust, waste gas treatment, dust extraction, process air supply, and material conveying applications in chemical manufacturing plants.
Chemical processes may involve corrosive gases, high temperatures, high humidity, toxic substances, flammable vapors, or aggressive chemical compounds. Therefore, fan materials and construction must be selected according to the actual gas composition and operating conditions.
EMS provides customized Chemical Centrifugal Fans, Chemical Process Fans, Corrosion-Resistant Fans, FRP Fans, Stainless Steel Fans, Chemical Exhaust Fans, and explosion-proof configurations for specific hazardous-area applications.
Main Chemical Fan Types

Chemical Process Fans
Used for process gas circulation, gas conveying, pressurization, exhaust, and air supply in chemical production systems.
Chemical Exhaust Fans
Designed to extract process fumes, chemical gases, odors, and contaminated air from production equipment and chemical plant areas.
Corrosion-Resistant Centrifugal Fans
Designed for corrosive gas applications involving acidic, alkaline, saline, or other aggressive media. FRP, stainless steel, and other suitable materials can be selected according to operating conditions.
Chemical Waste Gas Treatment Fans
Used to convey industrial waste gases to scrubbers, absorption towers, activated-carbon systems, filters, and other environmental treatment equipment.
Chemical Explosion-Proof Fans
Used in applications where flammable gases or vapors may be present. Explosion-protection requirements should be selected according to the hazardous-area classification and applicable local standards.
FRP Chemical Centrifugal Fans
FRP centrifugal fans are suitable for many corrosive exhaust applications involving acid mist, alkaline gases, and other chemically aggressive media.
Stainless Steel Chemical Fans
Stainless steel construction can be selected according to the chemical composition, concentration, humidity, and temperature of the handled gas.
Chemical Dust Extraction Fans
Used for extracting and conveying powders, particles, and process dust generated during chemical manufacturing.
High-Temperature Chemical Fans
Designed for high-temperature process gases, thermal processing, heating systems, and other elevated-temperature chemical applications.
Heavy-Duty Chemical Process Fans
Designed for demanding chemical processes requiring continuous operation, robust construction, and stable airflow performance.

Chemical Fan Design Features

Corrosion-Resistant Construction
Fan materials can be selected according to acidic, alkaline, saline, solvent-containing, or other corrosive gases. FRP, stainless steel, and customized corrosion-resistant materials are available depending on the application.
Waste Gas Treatment
Chemical waste gas fans can convey exhaust from production equipment to scrubbers, absorption towers, filtration systems, and other environmental treatment equipment.
Explosion-Proof Configuration
Where flammable gases or vapors may be present, the fan system can be configured according to the hazardous-area classification, gas characteristics, and applicable safety standards.
High-Temperature Operation
For elevated-temperature chemical process gases, suitable materials, shaft cooling, bearing insulation, and specialized sealing arrangements can be considered according to actual temperature.
Sealing Solutions
For toxic, corrosive, or irritating gases, appropriate shaft sealing and connection arrangements can be selected according to the required leakage-control conditions.

Customized Chemical Fan Engineering
EMS can engineer and select chemical industrial fans according to:
- Airflow
- Static / Total Pressure
