How to Choose a Fan
Correct fan selection starts with the actual operating conditions — not with a model number. Before a fan can be recommended, the following points should be established:
What must the fan do — ventilation, exhaust, combustion air, dust extraction, process air or cooling?
Airflow alone is not enough. The system resistance generated by ducts, filters, scrubbers and dampers must also be defined.
Temperature, dust concentration, moisture and chemical composition determine material and wear protection.
Available space, inlet/outlet direction, motor power, voltage, frequency and speed control.
Wear-resistant impellers, heat-resistant structures and bearing cooling arrangements where required.
Operating hours per day and duty cycle determine bearing, motor and structural configuration.

| Parameter | Unit | What It Determines |
|---|---|---|
| Airflow | m³/h, CFM or m³/s | Required process volume and operating range. |
| Total Pressure | Pa, kPa, mmH₂O or inWG | System resistance including ductwork, equipment and fittings. |
| Gas Temperature | °C / °F | Normal and maximum operating temperature. |
| Gas Composition | — | Corrosive, acidic, alkaline or solvent content. |
| Dust Concentration | g/m³ | Abrasion, deposition and wear protection requirements. |
| Application / Process | — | Where the fan sits in the process and what it must do. |
| Installation Dimensions | mm | Available space, inlet/outlet position and drive arrangement. |
| Motor & Power Supply | kW / V / Hz | Motor power, voltage, frequency and speed control. |

Q1. What information do I need to provide for fan selection?
Airflow, total pressure, gas temperature, gas composition, dust concentration, application/process, motor power, voltage and frequency, installation dimensions, and a fan drawing or existing model if available.
Q2. Can you manufacture a fan according to our drawing or sample?
Yes. OEM production can be developed according to customer drawings, dimensions or existing fan samples where technically feasible.
Q3. How do I choose between a centrifugal and an axial fan?
Axial fans are often suitable for high airflow with relatively low pressure, while centrifugal fans are generally advantageous when higher system pressure is required.
Q4. What material should be used for corrosive gases?
There is no universal material. SS304, SS316, carbon steel with coatings or other materials should be selected according to gas composition, concentration and temperature.
Q5. Can fans be supplied for high-temperature applications?
Yes. Materials, bearings, cooling systems, shaft design and sealing can be adapted for high-temperature conditions up to approximately 450°C or according to the specific design.
Q6. Do you provide VFD-compatible fans?
Yes. Variable-frequency drives are available for applications with changing production loads, allowing airflow to be adjusted while reducing unnecessary energy consumption.
