Four Values That Define the Fan Direction
The model comes later. First define the application, airflow, pressure and medium condition.
Application
Workshop ventilation, dust collection, boiler draft, tunnel ventilation, chemical exhaust or process air.
Airflow
Required air volume in m³/h, based on process demand, hood size, room volume or existing equipment.
Pressure
Static or total pressure after duct, elbow, damper, collector and filter resistance are included.
Medium
Clean air, dust, hot gas, acid mist, humid gas or flammable gas determine the construction direction.
Quick Selection Path
Use this sequence to organize the inquiry. Complete information helps QIYUE FAN check the preliminary fan direction faster.
Describe the Site
Tell us where the fan will be used, what process it serves and what problem it needs to solve.
Send Key Data
Airflow, pressure, temperature, medium, duct layout and operating time are the core selection data.
Match Fan Type
Review whether a centrifugal, axial, boiler, dust collection, mine or corrosion-resistant fan is suitable.
Confirm Quotation
After the technical direction is clear, confirm model, motor, material, drive, outlet direction, quantity and delivery requirements.
From Capture Airflow to the Final Dust Collection Fan
Follow the complete system route: define the application, calculate airflow, add collector resistance, compare fan categories and then review the industry-specific working condition.
Industrial Dust Collection System
Review hoods, ducts, collectors and fan position.
Review System →Airflow Calculation
Calculate hood demand, active branches and duct area.
Calculate Airflow →Dust Collection Fans
Compare fan directions by airflow, pressure and medium.
View Fan Category →Cement Plant Fan Solutions
Review abrasive dust, pre-separation and wear protection.
View Cement Application →Core Information for Fan Selection
What system or process is the fan used for?
Required air volume, usually in m³/h.
Static pressure or total pressure, usually in Pa.
Normal air, hot air, flue gas or furnace exhaust.
Clean air, dust, acid mist, humid gas or flammable gas.
Voltage, frequency and motor requirement.
If You Do Not Know the Parameters
You can still send available site information. QIYUE FAN can review the possible direction before detailed confirmation.

Common Applications and Fan Direction
This table is a preliminary reference. Final selection still depends on the real operating point and working condition.
| Application | What to Check | Fan Direction | Related Page |
|---|---|---|---|
| Workshop Ventilation | Large airflow and general air exchange. | Axial Flow Fan / Centrifugal Fan | Workshop Ventilation |
| Dust Collection | Capture airflow, duct resistance, filter resistance and dust characteristics. | Dust Collection Fan / High-Pressure Fan | Dust Collection |
| Boiler Draft | Hot gas, flue gas and continuous operation. | Boiler Induced Draft Fan | Boiler Draft |
| Mine / Tunnel Ventilation | Long-distance ventilation, confined space and site safety. | Mine Tunnel Fan / Axial Fan | Tunnel Ventilation |
| Corrosive Exhaust | Acid mist, humidity and material compatibility. | FRP / Corrosion-Resistant Fan | Chemical Exhaust |
| Pneumatic Conveying | High pressure and conveying-system resistance. | High-Pressure Centrifugal Fan | Pneumatic Conveying |
