Industrial Fan Selection Inquiry Checklist
To select or customize an industrial fan correctly, buyers should provide airflow, pressure, gas temperature, gas medium, dust content, corrosion condition, altitude, power supply, installation layout, inlet and outlet direction, motor requirement, drive type preference, and application industry.
The more accurate the working condition data is, the easier it is for the manufacturer to recommend a suitable fan.
1. Airflow
Airflow tells the manufacturer how much air or gas the fan needs to move.
Common units include:
- m3/h
- m3/min
- m3/s
- CFM
If you are not sure about the airflow, provide the equipment capacity, duct size, process requirement, or existing fan nameplate for reference.
2. Pressure
Pressure tells the manufacturer how much system resistance the fan must overcome.
Common units include:
- Pa
- kPa
- mmH2O
- inWG
Please clarify whether the pressure is static pressure or total pressure if possible.
3. Gas Temperature
Gas temperature affects fan material, bearing design, motor protection, shaft design, and sealing.
For high temperature applications, provide:
- Normal operating temperature
- Maximum temperature
- Whether the gas temperature is continuous or temporary
- Whether insulation or cooling is needed
4. Gas Medium
The gas medium determines whether the fan needs special material or protection.
Examples:
- Clean air
- Hot air
- Boiler flue gas
- Dusty air
- Chemical gas
- Corrosive gas
- Humid gas
- Combustible gas
5. Dust Content
Dust affects fan wear, vibration, and maintenance.
Useful dust information includes:
- Dust concentration
- Particle size
- Abrasiveness
- Stickiness
- Moisture
- Whether the fan is before or after a filter
6. Corrosion Condition
If the gas is corrosive, provide the gas composition and concentration if possible.
Possible solutions include:
- Stainless steel
- FRP
- Anti-corrosion coating
- Special sealing
- Drainage or cleaning design
7. Altitude and Ambient Conditions
Altitude and ambient temperature can affect air density, motor selection, and fan performance.
Please provide:
- Installation country or city
- Altitude
- Ambient temperature
- Indoor or outdoor installation
- Humidity
- Rain, dust, or outdoor exposure condition
8. Power Supply
Motor selection depends on the site power supply.
Please provide:
- Voltage
- Frequency
- Phase
- Motor efficiency requirement
- Explosion-proof requirement
- VFD control requirement
9. Installation Layout
Installation details help avoid connection problems.
Useful information includes:
- Inlet direction
- Outlet direction
- Duct connection
- Available space
- Foundation size
- Existing equipment layout
- Horizontal or vertical installation
- Maintenance space
10. Application Industry
The same airflow and pressure may require different fan designs in different industries.
Please specify whether the fan is used for:
- Boiler
- Cement plant
- Chemical plant
- Dust collector
- Wastewater treatment
- Pneumatic conveying
- High temperature exhaust
- Industrial ventilation
- Environmental protection equipment

FAQ
What is the minimum information needed for fan selection?
At minimum, provide airflow, pressure, gas temperature, gas medium, application, and power supply.
Why is pressure important?
Pressure determines whether the fan can overcome system resistance. Without enough pressure, the required airflow may not be achieved.
Why does gas temperature matter?
Temperature affects material, bearing design, sealing, motor protection, and fan safety.
Can a manufacturer select a fan without complete data?
A preliminary recommendation may be possible, but accurate selection requires working condition data.
Can Zhichengfans help with custom fan selection?
Yes. Zhichengfans can recommend or customize industrial fans according to airflow, pressure, temperature, medium, material, drive method, motor, and installation requirements.
