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." Typical applications for HVLS fans fall ...
A 5-blade ceiling fan in a restaurant. HVLS fans are large-diameter ceiling fans, intended for large spaces such as large warehouses, hangars, shopping malls, railway platforms and gymnasiums. These fans generally spin at a lower speed but due to their large diameter, ranging between 7' and 24' (2.1 m and 7.3 m), can provide a large area with a ...
The company's focus shifted almost exclusively to fan sales, and the company started doing business under the name HVLS Fan Company. [ 1 ] In 2000, the company initiated a marketing campaign with mailers depicting their fans with a picture of the rear of a donkey and the caption "Big Ass Fan". [ 3 ]

When a centrifugal fan is specified for a given CFM and static pressure at conditions other than standard, an air density correction factor must be applied to select the proper size fan to meet the new condition. Since 200 °F (93 °C) air weighs only 80% of 70 °F (21 °C) air, the centrifugal fan creates less pressure and requires less power.

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 ...
