Best HVLS Fans Supplier in CHINA.
We provide One-Stop Ventilation and Cooling Solutions with large spaces, including Industrial Ceiling Fans, PMSM Fan and Commercial Ceiling fans.


A high-volume low-speed (HVLS) fan,also called an industrial ceiling fan, big fan, helicopter fan is a type of mechanical fan greater than 7 feet (2.1 m) in diameter. HVLS fans move air slowly and distribute a large volume of air at low rotational speed– hence the name “high volume, low speed.”

what is hvls fans 01
  • HVLS Industrial Fan is a super larger energy-saving fan with a diameter of up to 7.3 meters (24ft);
  • The airfoil Blade, which is developed with the advanced technologies and principle of aerodynamics;
  • A power of 1.5kw or less, that move a High Volume(13,800m³ /min) of air at a Low Speed and cools up to 1000 square meters;
  • Produce a large scale of natural wind, which leads to the double functions of ventilation and Temperature cooling, as well as dehumidification;
  • The Ideal solution to ventilation and cool the air in a large area.

How effective HVLS fan is?

Take an example you will understand well: An area of 1000 square meters with a ceiling height of 10 meters, can be covered by one HVLS fan with a diameter of 24ft (7.3 meters), with 1.5 kW in power consumption, 828,000cmh airflow, at a noise level 43dB. Amazing, right?

Typical applications for HVLS fans fall into two classifications—industrial and commercial.

Industrial Ceiling Fans

RTFANS – HVLS industrial ceiling fans have 6 long (NASA-spirit superhard alloy) blades that move big volumes of air whereas rotating at a snail speed.

The big industrial ceiling fans combine the appearance of standard ceiling-mounted HVLS fans and have related industrial load structures, which can be used to improve the air quality in manufacturing plants and large-scale industrial environments.

They operate with nominal noise to avoid creating disruptions and generate delicate flowing, making them ideal for cooling warehouses, shops, GYMS, and factories.

Commercial Ceiling Fans

Extra-large commercial ceiling fans are specially designed for large commercial places and smaller industrial areas. There are completely different specifications from those used in most homes or offices.

Applications of commercial HVLS ceiling fans are a gym, stadium, school hall, airport, hotel lobby, public area, small warehouses, workshop, etc. Installation height is from 4 to 6 meters.


RTFANS use PMSM for low noise, high performance, and efficiency. It is to boot characterized by swish rotation over the full vary of a variable speed motor, full force management at zero speed, and fast acceleration and fastness. To achieve such management, we tend to use field-oriented management FOC techniques (also observed as vector control) for our PMSM.

Large industrial & commercial fans driven by PMSM motors eliminate the need for reducer connecting rods, gears, and high-speed bearings, so there is no need to replace the oil. Reduce gears, thereby reducing bearing replacement and maintenance. Because it is maintenance-free, it extends the service life of large industrial fans greatly. It brings a fairly reliable experience for users.

In industrial applications, air conditioning is often too costly for large spaces. HVLS fans have non-comparable advantages with large area coverage at low energy consumption so it becomes the perfect ventilation and cooling solution for factories, warehouses, distribution centers, workshops, etc. It can prevent heat stress, increase worker comfort and the productivity of both workers and livestock.

HVLS fans are also used in commercial spaces, where air conditioning is more common, but increased air movement from ceiling fans can cost-effectively augment occupant comfort or prevent stratification. Typical commercial applications include shopping malls, churches, stadium, sports center, office buildings, airport terminal buildings, fitness centers and schools.

Fan and Cooler Combo

In both industrial and commercial applications, we can instal separately or combine an HVLS fan with air conditioning and evaporative coolers, and other ventilation equipment. HVLS fan is a fit partner to the cooling system because it can help move a sizeable amount of cooled air evenly inside the space area.


We aim to be a world-leading solution supplier specialized in large space ventilation and cooling. Join us to develop more and help our earth to be greener.
