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 centrifugal blower 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 centrifugal blowers are engineered for durability, corrosion resistance, and continuous operation – perfectly suited for the demanding environments of chemical manufacturing.

Why Chemical Plants Need Specialized Corrosion-Resistant Centrifugal Blowers

The chemical industry involves processing highly corrosive materials, including acids (HCl, H2SO4, HNO3), alkalis (NaOH, KOH), chlorides, solvents, and organic compounds. Standard blowers fail quickly in such environments. Our specially designed centrifugal blowers feature:

• Corrosion-Resistant Construction – SS304, SS316, SS316L, or epoxy-coated MS impellers and housings.
• Sealed Bearings – To prevent chemical vapor ingress and ensure long life.
• High-Efficiency Impeller Design – Backward-curved impellers for optimal airflow and pressure.
• Leak-Proof Shaft Seals – PTFE or mechanical seals for gas-tight applications.
• Explosion-Proof Options – For flammable solvent-based processes (ATEX/Flameproof).
• Low Maintenance – Designed for 24/7 continuous chemical plant operation.

Key Applications of Centrifugal Blowers in Chemical Industry

• Fume Extraction & Ventilation – Removing corrosive acid fumes, solvent vapors, and toxic gases from reactors, storage tanks, and processing areas.
• Pneumatic Conveying – Transfer of powders (lime, soda ash, pigments, catalysts, polymers, plastic granules).
• Product Drying – Air drying of chemical powders, crystals, and granules after filtration or centrifugation.
• Spray Drying – Air atomization and drying in catalyst, dye, and specialty chemical manufacturing.
• Aeration & Agitation – Air supply for oxidation reactions, fermentation in bio-chemical processes.
• Combustion Air – Air supply for thermal oxidizers, incinerators, and process heaters.
• Cooling Applications – Air cooling of chemical intermediates and finished products.
• Bag Filters & Dust Collection – Reverse pulse jet cleaning in pollution control systems.
• Scrubber Air Supply – Air flow for venturi scrubbers and packed bed scrubbers.
• Vapor Recovery Systems – Air blowers for vapor return lines during tank loading/unloading.

Material Options for Corrosive Chemical Environments

Depending on the chemicals processed in your plant, we offer different construction materials. Our team can recommend the optimal material based on the specific gases, vapors, or particulate being handled:

Material Selection Guide

• Mild Steel (MS) with Epoxy/PU Coating – For mildly corrosive environments like fertilizer plants, salt handling, non-corrosive dust applications.
• Stainless Steel SS304 – For moderate corrosion resistance in chemical plants handling organic compounds, weak acids, and alkalis.
• Stainless Steel SS316 / SS316L – For highly corrosive environments involving chlorides, strong acids (H2SO4, HCl), and aggressive solvents. Preferred for most chemical applications.
• SS316 with PTFE / ETFE / PFA Coating – For extreme chemical resistance applications with highly aggressive acids and solvents.
• FRP (Fiber Reinforced Plastic) – on request – For low-pressure, highly corrosive fume extraction applications.
• Cast Aluminum / Aluminum – For spark-resistant applications in explosive atmospheres (flameproof/ATEX).

Quality Assurance & Testing

Every centrifugal blower leaving our Ahmedabad factory undergoes:

• Dynamic balancing of impeller (ISO 1940 G-6.3 grade, G-4.0 for high-speed units)
• Performance testing for airflow, static pressure, and power consumption
• Vibration and noise level measurement
• Leak testing for gas-tight applications (for fume extraction and VOC handling)
• Coating thickness verification for epoxy-coated/PTFE-lined models
• High-temperature run test (for high-temperature applications)
• Material certification for SS304/SS316 (Mill Test Certificate)
