   These fans are often used in mining applications. Variable pitch on-the-fly axial fans – These are similar to “Variable Pitch Axial Fans” except they include an internal mechanism that allows the blade pitch to be adjusted while the fan rotor is in motion. These versatile fans offer high-efficiency operation at many different points of ...

   The company had expanded into industrial ventilation, heating, air conditioning, dust and fume removal, power, drying and vacuum cleaning. In 1906, Sturtevant installed the first industrial air conditioning system at Walter Baker & Company in Dorchester , and, at a Chicago hotel in 1910, the first residential air conditioning system.

4. Centrifugal fan - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_fan

   Therefore axial fans are usually used for high volume air movement, such as warehouse exhaust or room circulation, while centrifugal fans are used to move air in ducted applications such as a house or typical office environment. The centrifugal fan has a drum shape composed of a number of fan blades mounted around a hub.

5. Fan (machine) - Wikipedia

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

   Some fans may be indirectly used for cooling in the case of industrial heat exchangers. While fans are effective at cooling people, they do not cool air. Instead, they work by evaporative cooling of sweat and increased heat convection into the surrounding air due to the airflow from the fans. Thus, fans may become less effective at cooling the ...

6. 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."

7. Duct (industrial exhaust) - Wikipedia

   en.wikipedia.org/wiki/Duct_(industrial_exhaust)

   Industrial exhaust ducts are pipe systems that connect hoods to industrial chimneys through other components of exhaust systems like fans, collectors, etc. Ducts are low-pressure pneumatic conveyors to convey dust, particles, shavings, fumes, or chemical hazardous components from air in the vicinity to a shop floor or any other specific locations like tanks, sanding machines, or laboratory hoods.
