HVLS FAN

Patented PM Direct Drive Technology | Industrial HVLS Ceiling Fan Manufacturer

World-leading permanent magnet synchronous motor solves external rotor overheating. Ultra-large coverage with natural airflow, 5-12m installation height. Cuts cooling costs by 50% vs. traditional HVAC—recoup investment in first year.


Leveraging world-leading permanent magnet synchronous direct drive motor technology and modern aero wing technology, the permanent magnet direct drive HVLS energy-saving ceiling fan rotates slowly via high-diameter blade, so as to drive air flow in all directions and generate natural circulating air in broad area. Air flow in vast coverage accelerates volatilization of sweat on the surface with air died and dehumidified and stratification of cold and heat cleared, thus resulting in natural ventilation and cooling. Compared with traditional HVAC and small-sized high-speed draught fans or asynchronous motor-reducer first-generation industrial fans, it has unrivalled virtues of high efficiency, energy conservation, mute, presentability, broad coverage, simple structure, maintenance free, long service life, etc. , which is hailed as the most cost-effective large-space ventilation and cooling solution.
The fan in low-speed operation gives rise to air circulation in vast area, for ventilation inside and outside the space. With natural air mildly cooling people and devices, it brings down room temperature and blows away dust and smoke in the air, for the sake of environmental protection.





Adjustment of air humidity and maintenance of dryness



Bring down indoor air humidity and keep dry, in case goods get damped and mouldy and devices get rusted.

High and adjustable air capacity and broad coverage

With coverage of 1500 sqm the maximum, single GF73 fan can substitute nearly 48 industrial claw fans with diameter of 750mm.

High cost performance

The least investment yields the best effects. The installation of air conditioning is a packet in large space, but general ventilation equipment works not well. In contrast, GF fan users can recover the installation cost by electricity charges saved in the first year.

High efficiency and energy conservation

GF fans feature utterly low power consumption. GF73 with the largest diameter consumes less than 1 kw of electricity per hour on average, which is an energy-saving, carbon-free and nature-friendly expert.

Substitute for cool air conditioning

The fan engages people in temperature difference of 5-10℃, which rotates with traditional air conditioning in some occasions. Therefore, it can replace the central air conditioning to a certain extent.





Air circulation in all directions and angles, ventilation with no dead zone Air is thrust to conically flow top down towards the ground and to horizontally flow on the ground. In case of any lateral obstruction or horizontal air flow of neighboring fans, it is pushed upward to the roof, so as to strengthen air circulation in all directions and angles. Exchange with outdoor fresh air and smoke and dust removal for creating a better air environment Air can rapidly exchange with outdoor fresh air via doors/windows or fans atop. With less dirty and muggy air indoors, the indoor air environment is cleared. Easy installation, safety and presentability Mounted 4.5m above the ground, the fan is securely clamped on the structural beam of roofing. With no impact on any normal progress in any ground working area, it is nice-looking, simple, elegant, secure and solid.

Patented cooling structure


The fan is arranged with a proprietary high-efficiency permanent magnet direct drive motor that weighs 45KG. The motor is lighter with output in low speed but high torque.

Reducer free

The reducer-free motor with much lower mounting height accommodate occasions of various dimensions.

Lifelong maintenance free

In need of no regular refueling or lubrication, the motor is designed for long-term use upon installation.

Ultra-low temperature rise

The unique 3D convective heat dissipation structure with ultra-low temperature rise makes sure of no demagnetization.

Long service life

The long service life of motor is guaranteed by enamelled copper wires with thick film and double row angular contact ball bearings for high-load use.



(Note: GF73 prototype made in the Company's workshop has temperature rise of 45K in measurement)


Anti-fall design Bottom up the motor shaft is stepped anti-fall design with the bottom wider than the top. The motor shaft is directly connected to the mounting frame, in case the rotary part of the motor falls.
Energy-saving design With higher efficiency and broader high-efficiency range, the motor is more energy-saving than average asynchronous motor-reducer unit, which consumes less than 1kw of electricity per hour.
Stable operation The fan is started up and shut down smoothly, with no jitter or impact therein. With adjustable air quantity, the fan outputs sina wave and makes stable operation. Leveraging unique rate tracking technology, the fan be steadily restarted during ongoing operation.
Silence Free from mechanical transmission, the fan adopts high-precision, heat-resistant and heavy-load silent bearings; the muted permanent magnet motor runs quietly with no mechanical noise made.

Diagram of airflow

Semi-open space In a semi-open factory, the product can drive air to move downward and make fresh air outside fill the negative pressure area atop, so as to secure abundant supply of cool and fresh air in the working area.

Multi-fan parallel operation In large space, it is hard to cool all corners by a single fan. A plurality of fans reasonably arranged in the space can generate air circulation to cool the space and refresh air indoors.

Enclosed space Air flows slowly in an enclosed workshop, where people may be easily sweltered. The vast inflow of air with no dead zone inducing air circulation in the enclosed space can relieve people from feeling muggy unbearably.
