Boiler ID Fans & FD Fans
ID (Induced Draft) and FD (Forced Draft) fans are essential components in industrial boiler and thermal system operations. As a key type of large-scale industrial fans, they are engineered to perform reliably under high-temperature, high-pressure, and heavy-duty working conditions.
FD fans supply a steady flow of fresh air into the boiler combustion chamber to ensure optimal fuel burning, while ID fans efficiently extract hot flue gases, maintaining the required negative pressure inside the furnace for safe and efficient boiler operation.
We offer a wide range of heavy-duty centrifugal fans specifically designed for boiler applications in power plants, chemical industries, metallurgy, cement production, pharmaceuticals, and cogeneration systems. Our fans are built for continuous operation, low noise, and high efficiency.

Frequently Asked Questions
Find answers about boiler ID fans, FD fans, industrial centrifugal fans, high-temperature applications and custom engineering solutions.
What is the difference between ID fan and FD fan?
FD fans (Forced Draft Fans) supply combustion air into the boiler system, while ID fans (Induced Draft Fans) extract high-temperature flue gas and maintain negative furnace pressure for stable boiler operation.
What temperature can boiler ID fans handle?
Our industrial boiler ID fans can be designed for high-temperature operation up to 850°C using heat-resistant materials such as SS304, SS316 and AISI 310S stainless steel.
Can boiler fans be supplied with VFD control?
Yes. Variable Frequency Drive (VFD) control is available for airflow adjustment, energy saving and stable boiler combustion control.
What materials are used for boiler centrifugal fans?
Boiler centrifugal fans are commonly manufactured using carbon steel, SS304, SS316 or high-temperature resistant AISI 310S materials according to operating conditions.
Do you provide custom industrial boiler fan solutions?
Yes. We provide custom airflow, pressure, temperature and structural designs according to boiler capacity, fuel type and industrial operating conditions.
