HVLS Fan & Air Cooler Manufacturer.
It’s a combination of large industrial HVLS ceiling fans and Evaporative air coolers, also is used both the advantages of these two products.
What is Fan & Cooler Combo?
It’s a combination of HVLS fan and Evaporative air cooler. The concept is to use both the advantages of the two products. With fresh cooled air from air cooler and high volume low-speed air movement from HVLS fan, you will get a perfect environment with the lowest cost; fresh cooled air can be distributed to every corner. Compare with using only one product, it cost too much for an air cooler to use the ducting system but only gets spot cooling; HVLS fan can make air circulation but it’s not enough because in the hot season people need cooled air.
Fan and cooler combo realize a perfect solution for big space cooling and ventilation, no matter indoor or outdoor. The unique advantage of an air cooler is that it can drop air temperature with only 20% power consumption compared to traditional AC, but need air ducting hang on the ceiling which impacts space utilization and image.
The unique advantage of HVLS is the high volume low-speed air movement ability, each fan enables to cover more than 1000 square meters, but can’t get temperature drop; Fan & Cooler Combo take both advantages and can provide optimized ventilation and cooling environment for users.
- Fresh and cooled air is dispensed into every corner of the building, bring soft breeze in all directions.
- High volume, low speed, better environment.
- No ducting in building, cost-saving, and space utilized, neat and easy to organize.
- The system can be used together or independently: In the hot season, the fan & cooler combo system work the best; in the less hot season, can use HVLS fan or air cooler only for ventilation or cooling purpose.

HVLS fans can provide a high volume of air at low speed; therefore, they are named HVLS that stands for 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.
The size of big HVLS fans depends on the type of fan. There usually two types of large HVLS fans that are, Industrial HVLS fans and Commercial HVLS fans. While RTFANS has one more type which is PMSM HVLS fans. You can select the fan according to the area of your place.
All these fans are excellent to provide fresh air to the environment. Their high airflow creates a chill effect of 5-8˚C. The airflow can be up to 13,500 cubic meters/minute. Due to excellent airflow, they send a well-aligned wind to a huge area. They can also reduce the humidity of the area. They reduce your energy bill because you only need to use a few units of them, and they assist your main cooling system as well. Overall, these fans are excellent for large areas such as terminal stations, shopping centers, and factories.
How do Ceiling Fans cool a room?
RTFANS big industrial ceiling fans can provide a chill effect to the people in the area. This chill effect can be around 5-8˚C.
Large industrial ceiling fans do not cool a room like an air conditioner. The question arises is, “How do people feel cooling effect due to huge industrial ceiling fans?” The answer is simple, due to the high volume of air and accelerated airflow, the evaporative efficiency of sweat is increased. Whenever evaporation happens, it takes the energy from the body and provides a cooling effect. This cooling effect is also known as the chill effect. In the human body, the evaporation of sweat is accelerated due to high airflow from big industrial ceiling fans. The sweat evaporates and provides a cooling sensation to the person. This is the reason that people feel the cooling effect due to large industrial ceiling fans. They feel more comfortable and fresher.
RTFANS big industrial ceiling fans have the capability to provide chilling sensation from 5˚C-8˚C. They can provide healthy and fresh air for the people in the area. In normal temperature when you don’t need an air conditioner, these fans can be beneficial, they can save you’re the energy used by air conditioners.
All RTFANS big industrial ceiling fans can provide this cooling sensation, you can buy all our products in India, Philippines, China, and other countries at a reasonable price.
How do I install RTFANS HVLS Fans?
RTFANS large industrial ceiling fans come with a Cardan Joint. It is just like a human-joint that decreases the vibration of the fan. It makes the fan safe to use. In most cases, the beams are not straight, they are tilted, so the Cardan Joint will help you to align the fan perfectly. Your fan will be oscillation-free.
The third step is the installation of the extension rod at the end of the Cardan joint. This rod allows you to set the height of the fan according to the height of the place. One end of the extension rod is connected to the Cardan joint and the other is connected with a drive device.
The Drive Device is the main thing that will rotate the fan blades. You can now connect the drive device to the extension rod. You need 2-3 people to lift it because it is heavy.
Now you need to connect the power supply to the motor. You need to take wires to the fan using sleeves and conduit. It is better to make a simple conduit layout to make everything easy. The power supply should be off while you are working. Otherwise, there is a high risk of electric shocks. If you have 380V at the place, then connect the fan in y-type of wiring. But if it is 220V, then connect in delta-type. After connection, you can install the control box.
You will get four steel wire ropes to connect the fan with the building structure. It is an excellent safety measure to prevent any accidents. You can insert eye-bolts in the building structure. Use the turnbuckle screw to connect the steel wire with the safety ring of the fan. The angle between the fan and the ropes should be 45˚. After installation of the ropes, tight them using the turnbuckle screw and make sure that the fan is in the vertical position. You should use a leveling instrument for the purpose.
There is a wire rope connected with the motor frame and wound on the roof steel structure. It forms a closed loop which a good safety measure.
Now insert the empennage to the airfoil blades and connect it using bolts. Make sure everything tightened perfectly.
Insert the airfoil blade into the blade pin and tighten it using bolts. Connect the safety locks from one blade to another. It will prevent the blades from falling.
The last step is to install the bottom cover and tighten it using bolts.
