Best industrial ceiling fans for sale | RTFANS.

What is big industrial ceiling fans?

RTFANS - HVLS industrial ceiling fans have 6 long (NASA-spirit superhard alloy) blades that move big volumes of air whereas rotating at a snail speed.
The big industrial ceiling fans combine a standard ceiling fan look associated associate industrial-duty build for current air in manufacturing plants and massive industrial settings.
A mounting bracket is capsulate for attaching these fans to a ceiling. These air circulators unit of measurement typically accustomed cool machinery and facilitate keep of us coz.
They operate with nominal noise to avoid creating disruptions and generate delicate flowing, making them ideal for school, cooling warehouses, shops, GYMS, and factories.

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 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 Fans 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 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 to improve the quality of air and provide a fresh, arid and safe environment.

Cordinate with AC

During Spring or Autumn when temperature keep in a range from 20-34 ℃, for those space with AC system, it’s awkward to decide if need to run the AC system, while with HVLS fan, you can forget the electricity bill caused by AC system!

It cost a huge when AC system fully running, while the HVLS fan can spread the cold air into every corner of the space during AC running, make it more well proportioned.

In addition, testing shows that we can save power consumption 20% by setting AC temperature 1℃ higher, HVLS fan can shorten the running time of AC or decrease the running quantity of AC, but achieve a same cooling effect!
