Long life Low Noise Energy Saving No Maintenance
The GF series permanent magnet direct drive HVLS energy-saving ceiling fan adopts internationally leading permanent magnet synchronous direct drive motor technology combined with modern aviation wing technology.Through the slow rotation of large-diameter blades,it drives the flow of airin all
directions,generating a large area of natural three-dimensional circulation wind.The large-scale airflow accelerates the evaporation rate of sweat on the surface of the human body,drying and dehumidifying, eliminating cold and hot stratification,and producing a dual effect of natural ventilation and cooling.
Compared to traditional HVAC systems and first generation industrial fans with small high-speed fans or asynchronous motor gearboxes,it has unparalleled advantages such as high efficiency,energy saving, quietness,beauty,large coverage area,simple structure,maintenance free,and long service life.It is
currently the most cost-effective ventilation and cooling solution for high-rise spaces.
Regulate air humidity maintain dryness | Featuring a large air volume and wide coverage area, the airflow can be freely adjusted | Exceptional cost performance Minimal | High efficiency and energy saving | Replace cooling air conditioners |
Reduce indoor humidity,keep the indoor environment dry, and prevent goods from becoming damp and moldy or equipment from rusting | The maximum coverage area can reach up to 1,500 square meters.A single GF73fan can replace nearly 48 industrial horn-shaped fans with a diameter of 750 mm. | investment,excellent results.In large spaces,the cost of installing air conditioning is too high,and typical ventilation systems are often ineffective. With GF fans,the installation cost can be recovered within the first year through electricity savings. | Extremely low power consumption,even the largest model,the GF73, consumes less than 1 kWh per hour on average.Super energy-efficient, low-carbon,and environmentally friendly. | It can create a perceived temperature difference of approximately 5to 10℃for the human body and,in certain situations, can be used alternately with traditional air conditioning systems,thereby to some extent achieving the effect of replacing central air conditioning. |
| All-around,multi- angle air circulation with no blind spots in ventilation | Exchanges with outdoor fresh air, expels smoke and dust, resulting in a better air environment | Easy to install,safe, and aesthetically pleasing |
The airflow is directed downward in a cone shape toward the floor, then flows horizontally along the ground. When itencounters side obstructions or horizontal airflow from nearby fans, it is pushed upward to the roof, thereby enhancing air circulation comprehensively and from multiple angles. | Flowing air can quickly exchange fresh air with the outdoors through doors,windows, or roof fans,reducing the retention of stale and stuffy indoor air, thereby purifying the environment. | The fan is installed in the upper space more than 4.5 meters above the ground and is fixed to the roof structural beams using a clamp mechanism. It does not interfere with any ground-level work activities and is aesthetically pleasing,simple, elegant,and safe. |
Stepped shaft design
Anti-fall design
●The motor shaftfeatures a
stepped design,larger at the bottom and smaller at the top, to prevent falling.It is directly connected to the mounting
bracket,ensuring that the
rotating parts of the motor
cannot detach.
More energy-efficient
●Higher efficiency and a broader high-efficiency range make it
more energy-efficient than conventional asynchronous motors with gearboxes,with power consumption not
exceeding 1kWh per hour.
Stable operation
●Smooth start and stop with no jolts or shocks during transitions.
●Airflow can be freely adjusted. Sine wave output ensures stable operation.
·The unique speed tracking
technology allows the fan to
restart smoothly even without a complete stop.
Ultra-quiet
●With no mechanical transmission components,it uses high-precision, high-temperature-resistant,
heavy-duty silent bearings.
The permanent magnet motor
features an ultra-quiet design, ensuring silent operation without mechanical noise.

Semi open space In a semi open factory building,this product can drive the air on the roof to move downwards, allowing fresh outdoor air to automaticallyfill the negative pressurearea of the roof,providing a large amount of cool fresh air to the work area to the maximum extent possible. | Multi machine parallel When the space area is too large,it is difficult for a single fan to effectively cool and dissipate heat from all spaces.With the reasonable layout and operation of multiple fans, air circulation can be generated between the fans,effectively cooling all spaces and updating indoor air. | Enclosed space The air flow in a closed workshop is slow,which can easily make people feel stuffy and hot.Providing air to a large area without dead corners can help create air circulation in the closed space,thereby alleviating the unbearable feeling of stuffiness and heat among workers. |
