HVLS Industrial Fan

A high-volume low-speed (HVLS) fan is a type of mechanical fan that is greater than 7 feet (2.1 m) in diameter. Large industrial ceiling 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.”

Compared to other fans, HVLS fans have very low revolutions per minute. However, due to their large size, they can provide a high volume of air at low speed. The diameter from one tail to another can vary from 2.8m (8ft) to 7.3m (24ft). The aerodynamic design for the blades is one of the outstanding advantages as well. Unlike the normal fans, RTFANS all huge HVLS fans have 5-6 blades and a patented airfoil design for better strength and flexibility.

What are HVLS Fans?

HVLS Fans

Typical applications of HVLS fans are for industrial and commercial use. In industrial applications, AC cost is too high and impractical for big spaces, while ventilation and cooling demand are high. Fans installed in spaces like factories, warehouses, barns, and distribution centers can prevent heat stress, which can improve work comfort levels and increase the productivity of both workers and livestock.

Large industrial ceiling fans are also used in commercial spaces, where air conditioning is more common–But increased airflow from ceiling fans helps to reduce cost greatly — expected to save 30% of operating costs. Typical commercial applications include shopping malls, churches, office buildings, airport terminal buildings, fitness centers, and schools.

HVLS Fans Wind Chill Effect

The gentle breeze brings by RTFANS industrial ceiling fans to our body can accelerate sweat evaporation and make people feeling cool. Usually, this sensible temperature difference created by the wind chill effect could be 5-8℃. In addition, the gentle wind from all sides created by the HVLS fan makes people more comfortable compared with a traditional powerful fan.

How to make people feel cooling down 5-8℃ by using high-volume low-speed fans?

The running of a big diameter industrial ceiling fan blade accelerates the airflow and increases the evaporative efficiency of the sweat on a human being’s body. And this evaporation process can take away heat from our body, that’s called the wind chill effect.

As for the specific influence created by different wind speeds, please check the graph aside, which can show you different temperatures with different wind speeds to make the difference that people feeling

HVLS Fan Space Ventilation

HVLS Fan Space Ventilation

Usually, the ventilation is restricted in a tall and large space, and the exhaust fan can barely work for the floor or corner of the building where people and equipment located, while HVLS industrial fan can solve these problems completely by sending a well-aligned wind in full space, coordinated with the evaporative air cooler, to improve the air quality and achieve a healthy and comfortable working environment.

HVLS Fans Dehumidification​

RTFANS HVLS industrial ceiling fan facilitates the flow of air and dispenses the damp to improve the comfort level for people in the house.

HVLS fan can accelerate the air mixing of the whole space which helps to distribute and absorb the odors, smoke, and humidity very well, thus improving the quality of air and providing a fresh, arid and safe environment.
