Axial Flow Fans for Chemical Industry
High-efficiency, corrosion-resistant axial flow fans engineered specifically for chemical processing plants – from fume extraction to process ventilation.
When chemical manufacturers across India need reliable, corrosion-resistant, and high-efficiency air handling solutions for their critical processes, they turn to Shivam Engineering & Fabrication. As a leading axial flow fan manufacturer for the chemical industry, we have supplied hundreds of units to chemical plants across the country – from small-scale units to large petrochemical complexes. Our axial flow fans are engineered for durability, corrosion resistance, and continuous operation – perfectly suited for the demanding environments of chemical manufacturing.
Why Chemical Plants Need Corrosion-Resistant Axial Flow Fans
The chemical industry involves processing highly corrosive materials, including acids (HCl, H₂SO₄, HNO₃), alkalis (NaOH, KOH), chlorides, solvents, and organic compounds. Standard fans fail quickly in such environments. Our specially designed axial flow fans feature:
- Corrosion-Resistant Construction – SS304, SS316, SS316L, or epoxy-coated MS housings and impellers.
- Aerofoil Bladed Impellers – High-efficiency design for optimal airflow with low power consumption.
- Bifurcated Design Option – Motor completely isolated from gas stream for aggressive fume handling.
- Sealed Bearings – To prevent chemical vapor ingress and ensure long life.
- High-Volume Airflow – Capable of handling up to 200,000+ CFM for large-scale ventilation.
- Explosion-Proof Options – For flammable solvent-based processes (ATEX/Flameproof).
- Low Maintenance – Designed for continuous 24/7 chemical plant operation.
Key Applications of Axial Flow Fans in Chemical Industry
- Fume Extraction – Removing corrosive acid fumes, solvent vapors, and toxic gases from reactors, distillation columns, and storage tanks.
- Plant Ventilation – Fresh air supply and exhaust of contaminated air from processing areas.
- Product Drying – Air drying of chemical powders, crystals, and granules after filtration or centrifugation.
- Process Cooling – Air cooling of chemical intermediates and finished products.
- Reactor Aeration – Air supply for oxidation reactions and chemical processes requiring air.
- Scrubber Exhaust – Air handling for venturi scrubbers and packed bed scrubbers.
- Dust Collection – Bag filter exhaust and cleaning air for pollution control systems.
- Storage Tank Venting – Pressure relief and vapor recovery from chemical storage tanks.
Bifurcated Axial Flow Fans for Corrosive Fume Extraction
For applications involving hot, corrosive, or explosive gases, we offer bifurcated axial flow fans where the motor is completely isolated from the gas stream. This design feature:
- Protects the motor from corrosive fumes, extending fan life significantly.
- Allows handling of gases up to 150°C without special motor construction.
- Ideal for chemical reactor fume extraction, acid fume exhaust, and solvent handling.
- Available in SS304, SS316, and epoxy-coated MS construction.
- Eliminates risk of motor spark ignition when handling flammable vapors.
Material Options for Corrosive Chemical Environments
Depending on the chemicals processed in your plant, we offer different construction materials. Our team at Shivam Engineering & Fabrication can recommend the optimal material based on the specific gases, vapors, or particulate being handled:
| Material | Application | Corrosion Resistance |
|---|---|---|
| MS + Epoxy Coating | Mildly corrosive (fertilizer plants, salt handling) | Good for general chemical exposure |
| SS304 | Moderately corrosive (organic compounds, weak acids) | Excellent for most chemical applications |
| SS316 / SS316L | Highly corrosive (chlorides, strong acids H₂SO₄/HCl) | Superior resistance to pitting and crevice corrosion |
| Cast Aluminum | Spark-resistant applications (flammable solvents) | Good corrosion resistance, lightweight |

Frequently Asked Questions – Axial Flow Fans for Chemical Industry
1. Which stainless steel grade is best for handling HCl and H₂SO₄ fumes?
For HCl (hydrochloric acid) and H₂SO₄ (sulfuric acid) fumes, Shivam Engineering & Fabrication recommends SS316 or SS316L with special coating or bifurcated construction. For highly concentrated acids, PTFE lining or special alloy construction may be required.
2. Can your axial flow fans handle explosive solvent vapors?
Yes. We offer ATEX-certified and flameproof axial flow fans with spark-resistant aluminum impellers, bifurcated construction, and explosion-proof motors (Exd) for handling flammable solvents like acetone, toluene, methanol, IPA, and ethyl acetate.
3. What is the typical CFM requirement for fume extraction in a chemical reactor area?
Fume extraction typically requires 5,000-30,000 CFM depending on the reactor size, number of reactors, and ducting length. Our team can calculate the exact requirement based on your plant layout.
4. What is a bifurcated axial fan and when should I use it?
A bifurcated axial fan from Shivam Engineering & Fabrication has the motor isolated from the gas stream, allowing it to handle hot, corrosive, or explosive gases without damaging the motor. Use it for chemical reactor fume extraction, acid fume exhaust, or any application where the gas is aggressive.
