KQ Series-HVLS Large Ceiling Fans

KQ Series-HVLS Large Ceiling Fans

Extra large ceiling fans is the high volume low speed fan used for large open space for cooling and ventilation. You now have an efficient and cost effective way to stay cool in summer and warm in the winter. The sleek revolutionary design of our fans will look great in any commercial or industrial setting.

Specification-extra large ceiling fans

*Fan sound are teated in expert lab by running on maximum speed,and noise may vary due to  different environments and surroundings.

*Weight excluded mounting bracket and extension tube.

Details of large industrial ceiling fan

 1. Aerodynamic Design: The blades feature an aerodynamic profile engineered through computational fluid dynamics (CFD) optimization, delivering 23% greater airflow volume, 18% higher energy efficiency, and 35% wider coverage compared to conventional fan blades.

  2. Premium Material Construction: Forged from aerospace-grade 6063-T6 magnesium-aluminum alloy through precision die-casting, these blades achieve Vickers hardness of 85 HV while maintaining exceptional corrosion resistance (withstands 500-hour salt spray testing per ASTM B117).

  3. Advanced Surface Engineering: A multi-stage powder coating process creates a 50-70μm oxide ceramic matrix composite (CMC) layer, demonstrating >9H pencil hardness and UV resistance exceeding 3,000 hours per ASTM G154.

  4. Reinforced Structural Architecture: The dual-phase reinforcement system combines radial stiffening ribs (3mm thickness) with iso-grid safety webbing, achieving 1520 MPa yield strength while reducing turbulent energy loss by 42% through optimized mass distribution.

Advantages

1.Low AC Cost

2.Improve working climate & employees productivity

3.Nature Air Cooling &Ventilation

4. Keep healthy and large fresh Air Reducing bacteria,fog, mildew caused damage Drying the Wet Areas.

Functions

1.Well ventilation and cooling

KQ series of large fans to generate natural breeze blowing on the human body, promote the evaporation of sweat to take away heat, and make the human body cool, bring cooling feeling.

Usually, the body temperature can be decrease by 5-8 ℃. The three-dimensional natural wind blowing of large fans is more comfortable because:
On the one hand, the omni-directional three-dimensional blowing of the human body makes the evaporation area of the human body reach the maximum;
On the other hand, human beings have accumulated a kind experience of natural wind in nature. Once there is a natural breeze blowing with the change of wind speed, the human body will naturally feel extremely comfortable and cool.

2.Cost savings at every turn

Compared with small fan:
The area covered by a large open series fan with a diameter of 7.3m is approximately equal to the coverage area of 50 0.75m small fans. For example, in a  factory building with 9000 square meter, in order to achieve full coverage effect, it needs about 300 small fans, while only 6 large fans are needed to achieve the same effect . If the 6 sets OPTFAN have being used for 4 years, 8 months per year, 10 hours per day, the total operation time is about 10000 hours. The power consumption of large fans is 90000 kW · h, and the power consumption of small fans is 1080000 kW · h. The energy saving is 990000 kW · h and 92%!

3.Dehumidification  

Large ceiling fan for shop produces natural wind, which can promote the air flow of the whole space. If there is bad smoke and moisture in the room, the flowing air can be exchanged with outdoor air quickly through doors and windows or roof fans, so as to reduce the retention of indoor dirty air, so as to improve the indoor air quality and achieve the purpose of purifying air and dehumidification
