Facility structure requirements:H-beam,I-beam,steel-concrete square beam,circular steel structure,ordinary concrete beam etc. The center distance between fans should be at least 2.5 times than the diameter of the fan.

In order to avoid poor wind effect due to the insufficient airspace,the blades should be min 0.4m away from the roof.

Unique fan blade design

Picture Name

Design of teardrop-shaped fan blade section

1. We draw inspiration from the falling form of water droplets. The design of fan blades requires a large head and a small tail and a double-layer structure to minimize air resistance. The king engineer draws on the design of aviation wing section to make the fan blade section more like squashed water droplets, further reducing air resistance.

2. Minimize air resistance = reduce noise = reduce power = save energy

Picture Name

30 ° angle of attack, air volume strength doubled

After many tests, we found that the fan blade section and the level of 30 ° angle of attack can significantly increase the air volume, to achieve low-speed wind. However, if the traditional fan uses this angle of attack, it will lead to stall, air turbulence, increased noise and energy consumption.

Picture Name

Aerodynamic noise reduction

Inspired by the continuous arc transition of the eagle's wings, we designed the fan with the upturned tail to enhance stability, reduce turbulence and realize flexible air movement. At the same time, the continuous change of the angle of attack optimizes the efficiency of electric energy conversion and the sense of wind, and the use of aerodynamics to evenly distribute the airflow, which can produce smooth and silent diffusion airflow at low speed, effectively silencing and reducing noise.

Super energy saving

Energy consumption comparison chart

Picture Name

According to the air conditioning industry standard, a 15m space needs to be cooled by a 1P air conditioner with a power of about 0.75KW, while a 2 m diameter WS-Y series natural air circulation machine can cover a 50m space with an operating power as low as 0.01KW.

When the ambient temperature is less than 30 ℃, the WS-Y series natural air circulation machine can be used alone for ventilation and cooling; when the ambient temperature is more than 30 ℃, the WS-Y series natural air circulation machine and air conditioner can be used together to reduce the energy consumption of air conditioner by about 70%.
Compared with the traditional fan, after actual measurement, the effective energy saving rate of WS-Y series natural wind circulation machine is 50%, and the effective energy saving rate of air conditioner is 90%, which is matched with air.

The effective energy saving rate is more than 70%.

Extreme silence & somatosensory cooling

Picture Name

WS-Y series natural wind circulation machine operating noise <35dB, the permanent magnet synchronous direct drive motor directly connected to the movement device, eliminating the transmission mechanism, reducing the mechanical noise. Wing-type double-layer fan blades, continuous angle of attack changes and tail design all achieve noise reduction and flow stabilization effects.

Picture Name

The best feeling value of wind speed in human body is 1-3 m/s, and the fan speed is controlled at 0-90 rpm, which can realize somatosensory cooling of 7-9 ℃, with soft and comfortable wind feeling, saying goodbye to sultry heat and enjoying nature.

High efficiency permanent magnet motor

Large torque

Low speed

Equipped with a permanent magnet synchronous direct drive motor developed by the company, the motor has a large torque and drives the fan effortlessly.

small volume

Low energy consumption

The volume of the motor is about the 1/3 of the normal size, the structure is simple and there is no complex reduction gearbox, it is lighter and energy-saving, and the power consumption is only 1/4 that of the traditional motor.

Maintenance-free

Really safe

The motor is directly driven, without reducer, gear and high-speed bearings, eliminating oil replacement, realizing maintenance-free, and significantly improving the service life of the fan.

Multiple control modes

Picture Name

wall control

Visual operation, one-key start and stop, group control and other rich functions, easy to operate, with magnetic base, hand-held or wall hanging are just right.
