Choosing the right centrifugal boiler fan is essential for maintaining combustion efficiency, controlling fuel consumption, and ensuring the stability and lifespan of the entire system. Incorrect selection can lead to energy waste, weak pressure, or insufficient airflow for the boiler. The following information will help you understand How to choose the right centrifugal boiler fan for your manufacturing plant and select the most suitable equipment for your production needs. If you want a high-quality product, contact SUPER ONE for expert advice and support.
How to choose the right centrifugal boiler fan for your manufacturing plant.
Below is a detailed analysis of how to choose the right centrifugal boiler fan for your manufacturing plant:
Determine the correct airflow rate required.
Air flow rate (m³/h) is a crucial factor when selecting a fan. This is the amount of air that needs to be supplied or extracted to the boiler system.
- Calculated based on space volume and number of gas exchanges.
- Factory workshops typically require 10–30 exchanges per hour.
If the flow rate is insufficient: the furnace is inefficient.
If it is too high: it wastes electricity.
Select the appropriate pressure (head).
Pressure head (Pa) determines the ability to push/pull air through the piping system:
- Shorter tube, less flex → lower pressure
- Long pipe with many bends → requires high pressure
Especially with boilers, the system typically includes:
- Long pipeline
- Many dust filter devices
→ Medium or high pressure fans should be prioritized to ensure stable suction/discharge force.
Choose the type of fan based on the working pressure.
Centrifugal fans are divided into:
- Low pressure: high flow rate, low pressure → not suitable for boilers
- Medium pressure: balanced → commonly used
- High pressure: strong suction force, used for boiler systems and gas treatment.
Industrial boilers typically prefer high-pressure or medium-pressure fans.
Consider the temperature and working environment.
Boilers operate in the following environments:
- High temperature
- Lots of dust and exhaust fumes.
→ You need to select:
- Heat-resistant materials (thick steel, stainless steel)
- Indirect drive fan to protect the motor.
Choose the appropriate motor power.
Fan power depends on:
- Flow rate + pressure
- System scale
For example, large systems may require fans of 5–15 kW or more.
Choosing the right power rating helps:
- Save electricity
- Avoid overloading the motor.
Focus on performance and energy efficiency.
High-performance fans will:
- Reduce energy consumption.
- Long-term stable operation
Performance depends on the blade design, rotational speed, and machining accuracy.
Verify the actual system design.
Before choosing a fan, you need to evaluate:
- Pipeline length and structure
- Number of fittings, valves, and filters
- Boiler fuel type
These factors directly affect the fan’s operating point (flow rate – pressure).
Choose the appropriate drive type.
- Direct drive: high efficiency, compact
- Indirect drive: good heat resistance, suitable for boilers.
For boilers, indirect heating is recommended to increase durability.

Frequently Asked Questions about Choosing a Boiler Centrifugal Fan
How do I know if my current fan is underloaded or overloaded?
Measure the motor current when the boiler is running at full load. Compare it to the rated current indicated on the motor’s label. If the current is less than 80% of the rated current, it indicates underload (fan too large). If the current is higher than 100% of the rated current and the motor is overheating, it indicates overload (fan too small or system blockage).
Can FDF fans be used for IDFs?
It’s not recommended. FDFs are designed for clean air and low temperatures. IDFs must withstand high temperatures and dust. Using an FDF as an IDF will cause it to fail quickly and may even cause fires or explosions due to dust accumulating on the hot fan blades.
Should I buy a new fan or repair my old, broken one?
If your old fan is severely damaged (broken blades, bent shaft, punctured casing) and has been in use for over 7-10 years, you should buy a new one. If it’s only slightly damaged (worn blades, damaged bearings), repair will be more economical. SUPER ONE provides repair, blade replacement, and balancing services for old fans at only 30-50% of the price of a new one.
