Industrial Ceiling Fans for sale

HVLS Fan moves slowly and distributes large amounts of air at low rotational speed – hence the name “High Volume, Low Speed”.

HVLS Industrial Fan

A high-volume low-speed (HVLS) fan is a type of mechanical fan greater than 7 feet (2.1 m) 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 speed– hence the name “high volume, low speed.” These fans have very low revolutions per minute as compared to other fans. But due to their large size, they can provide a high volume of air at low speed.

The size of these fans can vary from 2.8m (8ft) to 7.3m (24ft). This is their diameter from one tail to another. Moreover, they have a different aerodynamic design as well. The blades are not like normal fans, they have a special aerodynamic design. The number of blades is also more than normal fans. RTFANS all huge HVLS fans have six blades and a patented airfoil design for better strength and flexibility.

Typical applications for HVLS fans are for industrial and commercial use. In industrial applications, AC cost is too high and impractical for big spaces, but ventilation and cooling demand is still high. Fans installed in spaces like factories, warehouses, barn and distribution centers can prevent heat stress, increase worker comfort and the productivity of both workers and livestock. HVLS fans are also used in commercial spaces, where air conditioning is more common, but increased air movement from ceiling fans can help to reduce cost greatly- a 30% running cost can be expected. 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 HVLS fans to our body can accelerate sweat evaporation and make people feeling cool, usually, this sensible temperature created by the wind chill effect can be 5-8℃, in addition, the gentle wind from all sides will make people more comfortable compared with a traditional powerful fan.

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

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

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

HVLS Fan Space Ventilation

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 whole space which helps to distribute and absorb the odors, smoke, and humidity very well, thus improving the quality of air and provide a fresh, arid and safe environment.
