- Propeller Fans: Ideal for moving large volumes of air in open spaces or for general ventilation.
Applications: Workshops, warehouses, poultry sheds, and large manufacturing spaces.
Centrifugal fans draw air into the center of a rotating impeller and expel it at a 90-degree angle, increasing the air pressure as it moves outward. They are suitable for applications requiring higher pressure and can handle particulate-laden or contaminated air.
- Radial Fans: Designed for handling dust, debris, and abrasive materials.
- Forward Curved (Multi-Vane) Fans: Used for low-pressure, high-volume applications.
- Backward Curved Fans: Offer higher efficiency and are suitable for clean air and light dust movement.
- Backward Lamina Fans: Preferred for drying and packaging lines in food processing.
Applications: Dust collection, HVAC systems, material handling, and industrial exhaust.
Tangential or cross-flow fans have long, curved blades and deliver air over a broad area at low pressure. They are commonly used for cooling electronic cabinets or providing even airflow across processes.
Industrial fans operate by converting rotational energy from a motor or turbine into kinetic energy, which moves air or gas through a system. The core components include:
- Blades or Impellers: Rotate to generate airflow.
- Hub and Shaft: Connect the blades to the motor and transmit rotational force.
- Motor: Provides the power needed for continuous operation.
- Housing: Protects internal components and directs airflow efficiently.
The operational principle varies between fan types. Axial fans propel air in a straight line, while centrifugal fans use centrifugal force to increase air pressure and direct it radially outward.
