Main Parts

HVLS Fan Motor

PMSM can be installed on the wheel shaft as a whole, forming an overall direct drive system, that is, a wheel shaft is a drive unit, eliminating a gearbox, completely sealed, and truly maintenance-free.

HVLS Fan Controller

Special designed servo controller, using an advanced full digital motor control algorithm, built-in over voltage, over current, overload, and short circuit protection, can read the real-time fan motor temperature and control the motor running in a safe temperature range. 

Safety Design

Adopt more than 10 safety protection measures (safety rope, safety ring, anti-drop  bushing technology, type I fan blade link, top 12.9-grade fastener, anti-loose fastener,  fan blade strengthening design, enhanced plug-in design, overload protection of  control system, etc.)
Fasten Blot and Nuts
Hanging Pole and Fan Hub
Safety Ring and Wire Traction

Application of HVLS fan

Which places are most suitable for installing HVLS fans?

Large workshop

Large workshops such as machinery processing plants, auto repair plants, aircraft assembly plants, and shipyards all use this fan. 

Large logistics warehouse distribution center

For logistics storage workshops, air quality can be improved, dehumidification and dehumidification can be prevented, and rust and decay of warehouse goods.

Business occasion

Large-scale industrial fans are also widely used in various commercial occasions,  As long as it is a large and high space occasion, industrial fans (commercial fans) will be hung, such as railway stations and bus stations, airports, military units, churches, stadiums, shopping malls, etc.

Large farm

Large industrial fans are also widely used in large farms, including dairy farms, feedlots and hatcheries. Good ventilation can improve air quality, dehumidify and deodorize, and reduce the incidence of livestock

Optimized Design of the Fan Drive and Direct Drive Motor:

1. The dedicated fan drive uses a fanless cooling design, even the fan cooling is not used, the temperature rise of our drive system is controlled within 20 degrees;
2. By optimizing the structural design, no traditional fan distribution box is needed to save investment and installation space for customers; 
3. Designed and optimized software to achieve better electromagnetic noise control goals; 
4. Developed corresponding protection programs according to the fan operating characteristics of various scenarios, enhancing safety Protective measures can realize overload protection, temperature protection and overvoltage protection, protection  against collision and severe dynamic imbalance
5. Intuitive operation interface allows users to directly operate without reading the user manual at a glance.

Installation Condition

Fixed mode Concrete roof beams or steel frames Two types of fixed splint
boom length ≤3m The length of the boom depends on the strength design
Install interval(S) 4D>S>6D Two sets of fan installation interval
installation space h1 >1/4D The distance of fan-blade plane from the roof
installation spaceh2 >D The height of the flat blade plane from the ground
Horizontal safe distance >1/4D Reduction in distance may increase in noise
Vertical safety distance >1/4D he vertical distance between the highest point of the obstacle and the blade


Regarding the noise test: under the condition that the rotation plane of the fan blade is> 8 meters from the ground and the rotation plane of the fan blade is> 2.5 meters from the roof, the vertical distance of the vertical line of the fan is 7 meters, and the sampling is carried out at a plurality of circumferentially distributed positions at a height of 1.7 meters on the ground Obtained reference noise data (the geometry of the roof and whether there are pillars around it will affect the noise test)

About comfort index characteristics

1. The fan produces wind speeds between 0.6m/s-2m/s
2. The ambient temperature is between 20 and 33℃
3. The relative humidity of the environment is between 50% and 85%
