Axial Flow Fans for Agro Chemicals Industry
High-efficiency, corrosion-resistant axial flow fans engineered specifically for agro-chemicals manufacturing and application – from drying and ventilation to air-assisted spraying.
When agro-chemical manufacturers and applicators across India need reliable, efficient, and corrosion-resistant air handling solutions for their critical processes, they turn to Shivam Engineering & Fabrication. As a leading axial flow fan manufacturer for the agro-chemicals industry, we have supplied hundreds of units to pesticide, fungicide, herbicide, and fertilizer plants as well as to air-assisted spraying equipment manufacturers. Our axial flow fans are engineered for high-volume airflow, durability, and resistance to corrosive chemicals – perfectly suited for the demanding environment of agro-chemical manufacturing and field application.
Why Agro-Chemical Industry Needs Specialized Axial Flow Fans
The agro-chemicals industry involves processing and applying highly corrosive materials, including acids, alkalis, solvents, and active ingredients. Furthermore, air-assisted spraying requires consistent, high-velocity airflow to carry droplets to target foliage. Standard fans fail quickly in such environments or cannot provide the required air jet characteristics. Our specially designed axial flow fans feature:
- Corrosion-Resistant Construction – SS304, SS316, or epoxy-coated MS housings and impellers.
- Aerofoil Bladed Impellers – High-efficiency, die-cast aluminum blades for optimal airflow.
- Adjustable Blade Angles – Typically 15°, 30°, and 45° to optimize airflow for different applications.
- High-Volume Airflow – Capable of handling up to 300,000 m³/hr (176,500 CFM).
- Bifurcated Design Option – Motor isolated from gas stream for handling hot/corrosive fumes.
- Low Noise Operation – Precision-balanced impellers for reduced noise levels.
- Low Maintenance – Designed for continuous 24/7 operation with minimal servicing.
Key Applications of Axial Flow Fans in Agro-Chemicals
- Product Drying (Pesticides, Fungicides, Herbicides) – Air drying after granulation, fluid bed drying, tray drying of formulated products.
- Plant Ventilation – Fresh air supply and fume/odor exhaust in processing and packaging areas.
- Fume Extraction – Removing corrosive chemical fumes from reactors, mixing vessels, and storage tanks.
- Air-Assisted Spraying (Field Application) – Generating high-velocity air flow to carry pesticide droplets to crop foliage in orchards and vineyards.
- Pneumatic Conveying – Transfer of powders, granules, and intermediates.
- Bag Filter & Dust Collection – Reverse pulse jet cleaning in pollution control systems.
- Cooling Applications – Air cooling of finished products after packaging.
- Greenhouse Ventilation – Climate control in agro-chemical research greenhouses.
Understanding Axial Flow Fans for Air-Assisted Spraying
In agricultural spraying, the axial fan establishes the airflow that contributes towards: reduction of drift and losses to the soil, increase in deposits and coverage of the lower layer of leaves, improved penetration of spraying drops, and the possibility to reduce doses and application volumes. Research has shown that the axial fan of an orchard sprayer must be flexible to supply enough airflow for different types of trees for precise pest application.
The performance of axial flow fans in spraying applications is primarily controlled by two parameters: fan rotation speed and blade angle. Studies have demonstrated that for each blade angle, if the fan speed increases, the air jet becomes more uniform. The maximum fan efficiency and system efficiency were obtained at a 30° blade angle and higher fan rotation speed.

Material Options for Corrosive Environments
Depending on the chemicals processed in your plant, we offer different construction materials:
- Mild Steel (MS) with Epoxy/PU Coating – For mildly corrosive environments like fertilizer blending, general ventilation.
- Stainless Steel SS304 – For moderate corrosion resistance in pesticide formulation areas.
- Stainless Steel SS316 / SS316L – For highly corrosive environments involving chlorides, strong acids, and aggressive solvents.
- Die-Cast Aluminum (LM-6) Impeller – High-strength, lightweight, corrosion-resistant aerofoil blades with adjustable pitch angles.
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.
- Allows handling of gases up to 150°C without special motor construction.
- Ideal for chemical reactor fume extraction, solvent handling, and acid fume exhaust.
- Available in SS304, SS316, and epoxy-coated MS construction.

Frequently Asked Questions – Axial Flow Fans for Agro Chemicals
1. What is the typical airflow requirement for drying pesticides?
Drying applications typically require 5,000-30,000 CFM depending on the dryer size and product moisture content. For larger industrial dryers, axial fans up to 176,500 CFM are available. Our team can calculate the exact requirement based on your process parameters.
2. How does blade angle affect axial fan performance?
As the blade angle increases, both the air velocity and volume flow rate increase, along with power consumption. At a 45° blade angle, you achieve maximum air capacity, while lower angles (15°) provide minimum fuel consumption. The optimum for balanced efficiency is typically 30°.
3. Can axial fans handle explosive dust or solvent vapors?
Yes. We offer axial fans with flameproof motors (Exd) and spark-resistant aluminum impellers for hazardous environments. Bifurcated axial fans with fully isolated drive systems are also available for handling explosive or corrosive gases.
4. What is a bifurcated axial fan and when should I use it?
A bifurcated axial fan 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 being handled is aggressive or hot.
