  ​Longer blades will create a wider column of air that is pushed downwards by an  HVLS fan . Airflow research conducted by Ramadan Bassiouny and Nader S. Korah published in a 2011 issue of Energy and Buildings showed that the maximum amount of airflow comes from the midpoint of a fan. Airflow is lowest in the center of the fan and at the very edge of blade tips. This is why you don’t feel as much airflow when standing directly under a ceiling fan as you would if you were standing slightly to the side of its hub. More blades might improve the velocity of air moving through the fan, but they don’t do anything to widen the column of air pushed out by the fan. Having more blades also increases the fan’s energy consumption. 1. The number of blades on a  ceiling fan  is important to its performance. While additional blades create more airflow fan weight and drag also increase, which requires the fan motor to work harder. Studies show that the airf...

  How Many Blades Should Your Industrial HVLSFan Have? When choosing a  large industrial fan , you would confuse and ask “How Many Blades Should My Fan Have?” Because you contact the fan manufacturers who have five blades and six blades, so you naturally want to ask this question! ​ As a member of industrial fan manufacturers, we can’t say whose fan is good, but let's talk about why we chosefivebladesfor the  industrial HVLS fan . 1. To influence the air volume is size of the windward area not the number of blades. The blade airfoil shape refers to the design principles of the propeller. The air flow   rate of the blade is huge when the fan works. 2. No sympathetic vibration, safety and low noise. With even number blades, two blades form a straight line, when one blade is affected by the airflow, the corresponding one will also vibrate, it is easy to damage the motor over time a...

  With the development of the times, people have more and more demands, among which there are strict requirements for the environment. Many large places, such as zoos and amusement parks, are a series of outdoor large-scale entertainment venues. When people gather, it is impossible to cool down by the environment. Therefore, a device that can solve outdoor large-scale entertainment venues is very important. Qixiang's big fan , with high air volume and low speed, solves the problem of cooling in outdoor places. With its unique inner rotor design, it overcomes the problem of mechanical damage caused by rain on mechanical products outdoors. Why is the Qixiang fan so special? First, the motor of the Qixiang fan is fully sealed, and only the internal output shaft drives the rotation of the chassis and fan blades, which greatly prevents the entry of water and dust. The protection level is IP64, which makes the life of the fan Longer. Second, the high-density rare-earth permanent magnet i...

About How  HVLS Fans  Function in a Logistics Facility Warehouses and logistics facilities generally encompass massive square footage filled with machinery, people and even light fixtures that all give off heat. These spaces can suffer from climate zones, poor air quality and uncomfortable temperatures that can cause both energy inefficiencies and safety concerns for managers to mitigate. If you are a Warehouse or Facility Manager looking at HVLS fans as a solution for your building, there are important features of HVLS fans that you need to examine when finding the solution to best fit your facility’s needs. Logistics facilities require speed and pacing. This type of activity and traffic builds heat in a variety of climates. This build-up of heat is especially prevalent in warm summer months when logistic facilities have bays and loading docks open, which transfers the heat into the facility. Through the use of HVLS fans, warehouse and logistic facilities can de-stra...

Imagine, when people sweat sweating in the gym, is there any way to make them feel comfortable? The existing cooling methods mainly include air conditioners, floor fans,  ceiling fans . First of all, the cold air blown out by the air conditioner is too cold. When a person is sweating, the cold wind will shrink the pores that are sweating, so that they cannot sweat normally, and the human body feels unwell. Secondly, the floor fan has a small coverage area, and the strong wind blows long and makes people feel dizzy and uncomfortable. Too many wires on the ground can easily trip people and cause electric shock. So the best way is install the ceiling fan in gym. Especially use the  HVLS ceiling fan . Install in ceiling can save the space. Also, it can cover a large space and with a slow speed. Makes people feel comfortable. At the same time, the circulating air keeps the entire gym from being stuffy. Qixiang   HVLS ceiling  fan , your best choice.

Industrial Ceiling  Fans  are becoming more and more popular nowadays. At the beginning, they were widely used in industrial yards and workshops. And then it went into commercial business. Whether it truly is summer timeor winter, it delivers even cool air. Even during an particularly humid day, the fan is consistently efficient. This is due to the smooth, heavy-duty motor and the 3 to 5 blades which are commonly 60 inches in length. Here are some brands and a brief description of each. All of these industrial ceiling fans are heavy-duty have durable motors which last long. They also are perfect for industrial plants or factories for the reason that they’re chemical-resistant and rust resistant and could cover and offer cool, air to a wider, spacious room. They’ve blades that could be applied in damp locations and you could successfully use them in location of air-conditioners. Because of the speed of the big ceiling fans, they readily circulate air even...
