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

Typical applications for HVLS fans fails into two classifications – industrial and commercial. In industrial applications, air conditioning is often cost-prohibitive or impractical. Fans installed in spaces like warehouses, barns, hangars & distribution centers can prevent heat stress, increase workers’ comfort and the productivity of both workers & livestock. HVLS fans are also used in commercial spaces, where air conditioning is more common, but increased air movement from ceiling fans can cost-effectively augment occupant comfort or prevent stratification. Typical commercial applications include shopping malls, churches, office buildings, airport terminal buildings, fitness centers, and schools.

In fact, energy-efficient HVLS fans have quickly assumed a leading role in the green building movement. The air from an HVLS fan moves toward the floor in a column that radiates in all directions, flowing horizontally until it reaches a wall or airflow from another fan -at which point it turns upward and flows back towards the fan. This creates convection like air currents that build as the fan continues to spin. Because of their size, HVLS fans are effective and efficient. Using 3/4-to-2-hp motors, they consume power at a fraction of the cost of multiple small ceiling fans.

Typical Applications

Industrial spaces, garments factory, dyeing spaces, retail spaces, shopping centers, health clubs, sports centers, schools, religious facilities, restaurants, theaters, stadium, airport, distribution and manufacturing facilities, daily/livestock barns and factories, etc.
