When a fan or a pump is run at half speed, it consumes a fraction of the energy needed to run it at full speed. Our variable speed drives are controlling fan and pump applications all around the world, and delivering significant energy savings for our customers.

A high-volume low-speed (HVLS) fan is a type of mechanical fan greater. 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 into two classifications—industrial and commercial. In industrial applications, HVACR is often cost prohibitive or impractical, and is usually only used for refrigerated warehouses or th
