ID Fan Manufacturer in India | Induced Draft Fan for Boilers & Power Plants
High Efficiency ID Fans with 55+ Years Experience & 2000+ Installations
Since 1978, we are a trusted ID Fan Manufacturer in India delivering high-performance Induced Draft Fans for boilers and industrial applications.
ID fan full form is Induced Draft Fan.
An ID fan is a critical industrial fan used to remove flue gases from boilers, furnaces, and power plants by creating negative pressure (draft) inside the system.
This ensures:
Efficient fuel combustion Proper airflow balance Safe exhaust through chimney
ID Fan Working Principle
The ID fan working principle is based on induced draft (suction mechanism):
- Flue gases are generated inside the boiler
- The ID fan creates negative pressure inside the furnace
- Hot gases are pulled through boiler passes and ducting
- Gases pass through ESP / Bag Filter
- Clean gases are discharged through chimney
Main Components of an ID Fan
A high-performance boiler ID fan consists of:
ID Fan Impeller
Handles dust-laden gases and provides energy to airflow
Casing (Volute)
Converts velocity into static pressure
Inlet Cone
Ensures smooth airflow entry
Shaft & Bearings
Transmits power and supports rotation
Motor
Drives the entire system
Dampers / IGV
Controls airflow and system efficiency
ID Fan Impeller Design
The ID fan impeller is designed to withstand extreme conditions:
Backward Curved Blades – High efficiency, low energy consumption Radial Blade Design – Best for dust & abrasive particles Wear Resistant Construction – Longer service life

FAQs?
What is ID fan full form?
Induced Draft Fan
What is ID fan used for?
To remove flue gases and maintain negative pressure
What is difference between ID and FD fan?
An ID Fan (Induced Draft Fan) and an FD Fan (Forced Draft Fan) are both essential in boiler systems, but they perform opposite functions.
Conclusion:
An ID Fan (Induced Draft Fan) is a vital component in industrial boilers and thermal power plants, ensuring efficient combustion, proper draft control, and safe removal of flue gases.
