Required air volume in m³/h or CFM. Airflow must match the process demand and active capture points.
Resistance from ducts, elbows, filters, dust collectors, dampers and discharge outlets.
Clean air, dust, smoke, heat, moisture or corrosive gas will affect fan type and material.
Outlet direction, rotation, motor position, foundation and maintenance access must fit the site.
A practical industrial fan selection should start from the system, not from the fan model. The same fan can perform very differently after it is connected to ducts, filters, dust collectors, dampers or high-temperature exhaust lines.
Check required air volume in m³/h, CFM or by room air change rate.
Include duct length, elbows, filters, hoods, dampers and discharge resistance.
Separate normal air, continuous hot air and peak-temperature exhaust.
Dust, moisture, sticky material, smoke and corrosive gas affect structure and material.
Compare centrifugal fan, axial flow fan, boiler fan, dust fan or corrosion-resistant fan.
Carbon steel, stainless steel, FRP, wear-resistant plate or coating may be required.
Send airflow, pressure, medium, temperature, layout and quantity for review.
Different industrial applications require different fan structures. This table gives a practical first direction before detailed model selection.
| Working Condition | Recommended Fan Type | Main Selection Focus | Related QIYUE FAN Page |
|---|---|---|---|
| General factory ventilation | Centrifugal fan or axial flow fan | Airflow, room size and installation position | Workshop Ventilation |
| Dust collection | Dust collection centrifugal fan | Dust type, filter resistance, particle size and impeller wear | C6-48 Dust Collection Fan |
| Baghouse dust collector | Baghouse fan / dust collector fan | Filter resistance, loaded-filter pressure drop and static pressure | Baghouse Fan Selection |
| Boiler induced draft | Boiler induced draft fan | Flue gas volume, dust collector resistance and temperature | Boiler Induced Draft System |
| Tunnel construction ventilation | Axial fan, local fan or jet fan | Duct length, leakage, pressure loss and working face distance | Tunnel Ventilation |
| Corrosive gas exhaust | FRP or corrosion-resistant fan | Gas composition, concentration, humidity and temperature | Chemical Plant Exhaust |
| High temperature exhaust | High-temperature centrifugal fan | Continuous temperature, peak temperature and motor position | High Temperature Exhaust |
Centrifugal Fans
Suitable for duct systems, dust collectors, filters, high resistance exhaust and industrial air delivery.
View Centrifugal Fans →Axial Flow Fans
Suitable for large airflow and relatively low-pressure ventilation such as wall, roof or tunnel airflow.
View Axial Flow Fans →Boiler Draft Fans
Used for forced draft or induced draft in boiler systems, flue gas lines and dust collector exhaust routes.
View Boiler Fans →Dust Collection Fans
Used with dust collectors, baghouses, hoods and ducts where dust type and abrasion must be checked.
View Dust Collection Fans →Mine & Tunnel Fans
Used for underground mine ventilation, tunnel construction ventilation and auxiliary local airflow.
View Mine & Tunnel Fans →Corrosion-Resistant Fans
Used for acid mist, chemical gas, humid corrosive air and exhaust systems requiring FRP or special material.
View Corrosion Resistant Fans →The more complete the working-condition information is, the more accurate the fan selection can be. A model name alone is not enough for stable on-site airflow.
| Parameter | What to Confirm | Why It Matters |
|---|---|---|
| Airflow | m³/h, CFM or air change requirement | Determines how much air must move through the system. |
| Static Pressure | Duct, elbow, filter, collector and discharge resistance | Decides whether the fan can still deliver airflow after installation. |
| Temperature | Normal, continuous high temperature and peak temperature | Affects casing, bearing, motor position and material selection. |
| Dust Condition | Dust type, concentration, particle size and hardness | Affects impeller wear, collector position and maintenance access. |
| Corrosive Gas | Gas composition, concentration, humidity and temperature | Determines whether FRP, stainless steel or coating is required. |
| Installation Layout | Duct route, outlet angle, rotation, motor position and space | Affects final structure, installation and maintenance. |
| Power Supply | Voltage, frequency, phase and motor protection requirement | Ensures the motor and control system match local site conditions. |

Choose carbon steel, stainless steel, FRP or high-temperature design.
How do I choose between a centrifugal fan and an axial flow fan?
Use an axial flow fan for large airflow and low resistance. Use a centrifugal fan when the system has ducts, filters, dust collectors, high pressure or process exhaust resistance.
What information is most important for selecting a dust collection fan?
Airflow, static pressure, dust type, dust concentration, particle size, particle hardness, filter resistance, duct layout and operating temperature are the key factors.
When should I choose an FRP corrosion-resistant fan?
Choose an FRP corrosion-resistant fan when the exhaust contains acid mist, alkali gas, chemical fumes, high humidity or other corrosive components.
Why is static pressure important in industrial fan selection?
Static pressure represents system resistance. If it is underestimated, the fan may not deliver enough airflow after it is connected to ducts, filters, elbows and discharge outlets.
Can QIYUE FAN recommend a model from working conditions?
Yes. Send airflow, static pressure or total pressure, temperature, medium condition, duct layout, outlet direction, voltage and quantity. QIYUE FAN can review the suitable fan type and model direction.
Can one fan model fit every industrial application?
No. Fan type, speed, material, motor power, outlet angle and transmission arrangement should be checked against the real operating point and installation layout.
Send your application, airflow, static pressure or total pressure, temperature, dust or corrosive condition, duct layout, outlet angle, rotation direction, motor standard and quantity. QIYUE FAN will review a suitable centrifugal fan, axial fan or special-condition fan direction for your project.
