2. Ceiling fan - Wikipedia

   en.wikipedia.org/wiki/Ceiling_fan

   Modern HVLS fans use airfoil-style blades for optimized air movement at a reduced energy cost. One of the most notable manufactures of HVLS fans is Big Ass Fans. A High-volume low-speed fan. Indoor/outdoor ceiling fans are designed for use in partially enclosed or open outdoor spaces. The body and blades are made of materials and finishes that ...

3. High-volume low-speed fan - Wikipedia

   en.wikipedia.org/wiki/High-volume_low-speed_fan

   A High-volume low-speed fan. A high-volume low-speed (HVLS) fan is a type of mechanical fan greater than 7 feet (2.1 m) in diameter. [1] HVLS fans are generally ceiling fans although some are pole mounted. HVLS fans move slowly and distribute large amounts of air at low rotational speed– hence the name "high volume, low speed."

4. Fan (machine) - Wikipedia

   en.wikipedia.org/wiki/Fan_(machine)

   A household electric fan A large cylindrical fan. A fan is a powered machine that creates airflow. A fan consists of rotating vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an impeller, rotor, or runner. Usually, it is contained within some form of housing ...

5. Axial fan design - Wikipedia

   en.wikipedia.org/wiki/Axial_fan_design

   An axial fan is a type of fan that causes gas to flow through it in an axial direction, parallel to the shaft about which the blades rotate. The flow is axial at entry and exit. The fan is designed to produce a pressure difference, and hence force, to cause a flow through the fan. Factors which determine the performance of the fan include the ...

6. Industrial fan - Wikipedia

   en.wikipedia.org/wiki/Industrial_fan

   The robust design allows high tip-speed operation, and therefore this fan is often used in high-pressure applications. Backward inclined – These fans have simple flat blades, backwardly inclined to match the velocity pattern of the air passing through the fan wheel for high-efficiency operation. These fans are typically used in high-volume ...

7. Turbofan - Wikipedia

   en.wikipedia.org/wiki/Turbofan

   A turbofan achieves this by using an additional turbine to drive a ducted fan to blow air that bypasses the high speed core. With a lower core thrust, most of the thrust now comes from the large mass of low speed bypass air, providing the same thrust with a reduced fuel burn. The other penalty is that combustion is less efficient at lower speeds.
